RESUMO

Gastric cancer is the fourth leading cause of cancer deaths worldwide. The presence of chemoresistant cells has been used to explain this high mortality rate. These higher tumorigenic and chemoresistant cells involve cancer stem cells (CSCs), which have the potential for self-renewal, a cell differentiation capacity, and a greater tumorigenic capacity. Our research group identified gastric cancer stem cells (GCSCs) with the CD24+CD44+CD326+ICAM1+ immunophenotype isolated from gastric cancer patients. Interestingly, this GCSC immunophenotype was absent in cells isolated from healthy people, who presented a cell population with a CD24+CD44+CD326+ immunophenotype, lacking ICAM1. We aimed to explore the role of ICAM1 in these GCSCs; for this purpose, we isolated GCSCs from the AGS cell line and generated a GCSC line knockout for ICAM1 using CRISPR/iCas9, which we named GCSC-ICAM1KO. To assess the role of ICAM1 in the GCSCs, we analyzed the migration, invasion, and chemoresistance capabilities of the GCSCs using in vitro assays and evaluated the migratory, invasive, and tumorigenic properties in a zebrafish model. The in vitro analysis showed that ICAM1 regulated STAT3 activation (pSTAT3-ser727) in the GCSCs, which could contribute to the ability of GCSCs to migrate, invade, and metastasize. Interestingly, we demonstrated that the GCSC-ICAM1KO cells lost their capacity to migrate, invade, and metastasize, but they exhibited an increased resistance to a cisplatin treatment compared to their parental GCSCs; the GCSC-ICAM1KO cells also exhibited an increased tumorigenic capability in vivo.

RESUMO

We propose a new family of distributions, so-called the unit ratio-extended Weibull family ([Formula: see text]). It is derived from ratio transformation in an extended Weibull random variable. The use of this transformation is a novelty of the work since it has been less explored than the exponential and has not yet been studied within the extended Weibull class. Moreover, we offer a valuable alternative to model double-bounded variables on the unit interval. Five [Formula: see text] special models are studied in detail, namely the: i) unit ratio-Gompertz; ii) unit ratio-Burr XII; iii) unit ratio-Lomax; v) unit ratio-Rayleigh, and vi) unit ratio-Weibull distributions. We propose a quantile-parameterization for the new family. The maximum likelihood estimators (MLEs) are presented. A Monte Carlo study is performed to evaluate the behavior of the MLEs of unit ratio-Gompertz and unit ratio-Rayleigh distributions. This last model has closed-form and approximately unbiased MLE for small sample sizes. Further, the [Formula: see text] submodels are adjusted to the dropout rate in Brazilian undergraduate courses. We focus on the areas of civil engineering, economics, computer sciences, and control engineering. The applications show that the new family is suitable for modeling educational data and may provide effective alternatives compared to other usual unit models, such as the Beta, Kumaraswamy, and unit gamma distributions. They can also outperform some recent contributions in the unit distribution literature. Thus, the [Formula: see text] family can provide competitive alternatives when those models are unsuitable.

RESUMO

The use of trace elements in agriculture as a complement to crop fertilization programs is a practice that is gaining importance and relevance worldwide. Iodine and selenium perform essential functions in human health, related to the proper functioning of the thyroid gland, acting as antioxidants and antiproliferatives, and their limited intake through food consumption can cause malnutrition, reflected in the abnormal development and growth of humans. This research aimed to evaluate the nutraceutical quality of tomato (Solanum lycopersicum L.) in response to seed priming based on KIO3 (0, 100, 150, 200, 250 mg L-1) and Na2SeO3 (0, 0.5, 1, 2, 3 mg L-1), performed by interaction from a 52-factorial design and by independent factors in a 24-h imbibition time. The tomato crop was established under greenhouse conditions in 10-L polyethylene containers containing peat moss and perlite 1:1 (v/v). Regarding non-enzymatic antioxidant compounds, lycopene, ß-carotene and flavonoid contents in tomato fruits significantly increased with KIO3 and Na2SeO3 treatments; however, vitamin C content was negatively affected. KIO3 increased the phenol and chlorophyll-a contents of leaves. In relation to enzymatic activity, KIO3 positively influenced GSH content and PAL activity in tomato fruits. KIO3 also positively influenced GSH content in leaves while negatively affecting PAL and APX activities. Na2SeO3 favored GSH content and GPX activity in tomato fruits and leaves. Na2SeO3 negatively affected the antioxidant capacity of hydrophilic compounds by ABTS in fruits and leaves and favored hydrophilic compounds by DPPH in leaves. Seed imbibition based on KIO3 and Na2SeO3 is a method that is implemented in the tomato crop and presents interesting aspects that favor the nutraceutical quality of tomato fruits, which may contribute to increasing the intake of these minerals in humans through tomato consumption.

RESUMO

The understanding of the molecular- and colloidal-structure of asphaltenes has seen a major progress; however, there are still issues that require answer. One of them is the location of the heteroatoms in the polycyclic aromatic hydrocarbon (PAH) fused aromatic ring (FAR) region of asphaltenes. Therefore, the effect on the frontier molecular orbitals (HOMO-LUMO) energy-gap due to the addition of a heteroatom (N or S) to PAHs, which are candidates of the PAH region in asphaltenes, has been systematically analyzed by placing S or N in various sites of the PAH molecule. The S is introduced as a thiophenic ring in a bay region, while the N is introduced as a pyridinic-N, which are prevalent forms in the asphaltene-PAH. 174 PAHs are studied with five fused aromatic rings (5FAR) to 10FAR. The π-electron allocation in resonant π-sextets and isolated double bonds is obtained using the Y-rule. The frontier orbitals optical transition is calculated with the ZINDO/S method. Within a FAR family an increment of π-sextets produces and increase of the HOMO-LUMO energy-gap. There is a linear relationship between the Y-rule mapping (percentage of fraction of π-sextet bond divided by nFAR) and the HOMO-LUMO energy-gap. In addition, the effect on the frontier orbitals energy-gap and on the π-electronic allocation due to the presence of N and S is negligible; therefore, to reach conclusions related to the asphaltene-PAH based on conclusions reached for PAH systems, with no heteroatoms, is a reasonable approach.

RESUMO

In many practical situations, there is an interest in modeling bounded random variables in the interval (0, 1), such as rates, proportions, and indexes. It is important to provide new continuous models to deal with the uncertainty involved by variables of this type. This paper proposes a new quantile regression model based on an alternative parameterization of the unit Burr XII (UBXII) distribution. For the UBXII distribution and its associated regression, we obtain score functions and observed information matrices. We use the maximum likelihood method to estimate the parameters of the regression model, and conduct a Monte Carlo study to evaluate the performance of its estimates in samples of finite size. Furthermore, we present general diagnostic analysis and model selection techniques for the regression model. We empirically show its importance and flexibility through an application to an actual data set, in which the dropout proportion of Brazilian undergraduate animal sciences courses is analyzed. We use a statistical learning method for comparing the proposed model with the beta, Kumaraswamy, and unit-Weibull regressions. The results show that the UBXII regression provides the best fit and the most accurate predictions. Therefore, it is a valuable alternative and competitive to the well-known regressions for modeling double-bounded variables in the unit interval.

RESUMO

Historical records (1980-2018) of potentially toxic phytoplankton and phycotoxins on the Argentine Continental Shelf (35°S-56.5°S) and adjacent ocean waters were systematically reviewed from scientific literature to assess their abundance and diversity over spatial and temporal scales. Records increased from 124 in the period 1980-1992 to 638 in 2006-2018, and the scanned area expanded from coastal to offshore waters including the shelf-break front. Alexandrium was the most reported genus (54%) during 1980-1992 and Pseudo-nitzschia (52%) during 1993-2005. By 2006-2018, a higher diversity was documented: Alexandrium (20%), Dinophysis (32%), Pseudo-nitzschia (31%), and the most recently described potentially toxic dinoflagellates of the family Amphidomataceae (8%). Likewise, a wider spectrum of phycotoxins was documented in the last decade, with lipophilic (LSTs) and paralytic shellfish toxins (PSTs) as the most recorded. Increased records are related to intensified monitoring, more detailed taxonomic analyses and more sensitive chemical techniques for marine biotoxin detection. This quantitative assessment brings light to the widespread occurrence of HABs along contrasting areas of the Patagonian Shelf and sets the basis for ecosystem risk evaluation. Moreover, comparison of toxic phytoplankton reported in the SW Atlantic with those in similar temperate seas in the North Atlantic and the Pacific Ocean, disclose ocean basin differences in strain toxicity of A. ostenfeldii, D. tripos and Azadinium species.

ABSTRACT The aims of this study were to determine and compare the cardiovascular risk (CVR) in students of the physical trainer career of the 2017 and 2019 generations. The variables measured were body weight (BW), height (HE), waist circumference (WC), body mass index (BMI) and waist to height ratio (WHtR). The WC and WHtR were used to determine the CVR and its subsequent comparison. The methodology used corresponds to a quantitative, cross-sectional, descriptive study: with a sample of 324 participants (year 2017 = 103 men and 61 women; year 2019 = 98 men and 62 women). A mechanical scale with a DETECTO brand stadiometer (for BW and HE) and a SECA anthropometric tape measure (for WC) were used. Sidak's two-way ANOVA test and multiple comparisons were used for statistical differences, the Cohen D index for effect size was considered, with an alpha of 0.05), nor are they classified as a risk group. It is concluded that female students have different anthropometric characteristics between both years and that the generation of 2019 presents CVR.

RESUMO

We study a five-parameter model called the Weibull Burr XII (WBXII) distribution, which extends several models, including new ones. This model is quite flexible in terms of the hazard function, which exhibits increasing, decreasing, upside-down bathtub, and bathtub shapes. Its density function allows different forms such as left-skewed, right-skewed, reversed-J, and bimodal. We aim to provide some general mathematical quantities for the proposed distribution, which can be useful to real data analysis. We develop a shiny application to provide interactive illustrations of the WBXII density and hazard functions. We estimate the model parameters using maximum likelihood and derive a profile log-likelihood for all members of the Weibull-G family. The survival analysis application reveals that the WBXII model is suitable to accommodate left-skewed tails, which are very common when the variable of interest is the time to failure of a product. The income application is related to player salaries within a professional sports league and it is peculiar because the mean of the player's salaries is much higher than for most professions. Both applications illustrate that the new distribution provides much better fits than other models with the same and less number of parameters.

RESUMO

Introducción: el Índice de Movilidad de De Morton® (en inglés De Morton Mobility Index: DEMMI®) es una escala, válida y fiable para evaluar la movilidad funcional del adulto mayor. Objetivo: validar una versión en español para pacientes hospitalizados en una sala general. Material y métodos: traducción y adaptación transcultural, evaluación de la fiabilidad interobservador y validación de criterio explorando la correlación entre los índices DEMMI y Barthel® al ingreso hospitalario y también entre la percepción subjetiva del cambio en la movilidad por parte del propio paciente y la del puntaje DEMMI, y además evaluando la asociación entre este y el grado de acompañamiento requerido en el egreso hospitalario (n = 87). Su consistencia interna fue evaluada mediante los coeficientes de Kuder y Richardson (KR) y de Cronbach (n = 104). Resultados: la correlación entre los puntajes DEMMI y Barthel fue buena (Spearman's Rho = 0,78: p ≤ 0,0001), mientras que la correlación entre la percepción del paciente respecto del cambio en su movilidad y la variación en el puntaje DEMMI fue moderada (Spearman's Rho = 0,50; p < 0,0001). Quienes fueron dados de alta con alto nivel de acompañamiento habían tenido al ingreso un puntaje DEMMI inferior (28,1; IC 95%, 24,9 a 31,3) al de quienes no lo requirieron (48; 44,4 a 53,0). La consistencia interna fue adecuada (KR = 0,827 y Cronbach = 0,745; Pearson's Rho = 0,7885; p < 0,00001). Conclusión: la consistencia interna y la fiabilidad interobservador de la versión en español del puntaje DEMMI son buenas, mientras que sus cambios tienen buena correlación con los percibidos por los propios pacientes. Consideramos que puede ser usado como un elemento más para estimar al momento del ingreso hospitalario, el grado de acompañamiento que requerirán al ser dados de alta. (AU)

Introduction: the De Morton Mobility Index (DEMMI) is a valid and reliable scale to evaluate the functional mobility of the elderly. Aim: validate a Spanish version for hospitalized patients in a general ward. Material and methods: translation and cross-cultural adaptation, evaluation of inter-observer reliability and criterion validation exploring the correlation between DEMMI and Barthel scores at hospital admission and also between the subjective perception of the change in mobility by the patient himself and that of DEMMI score, and also, evaluating the association between DEMMI and the degree of support required at hospital discharge (n = 87). Its internal consistency was evaluated using Kuder-Richardson (KR) and Cronbach (n = 104) coefficients. Results: correlation between DEMMI and Barthel scores was good (Spearman's Rho = 0.78: p < = 0.0001), while correlation between patient's perception of change in mobility and variation in DEMMI score was moderate (Spearman's Rho = 0.50; p < 0.0001). Those discharged with a high level of support had a lower DEMMI score upon admission (28.1; 95% CI 24.9 to 31.3) than those who didn´t require it (48; 44.4 to 53.0). Internal consistency was adequate (KR = 0.827 and Cronbach = 0.745; Pearson's Rho = 0.7885; p < 0.00001). Conclusion: internal consistency and interobserver reliability of the Spanish version of DEMMI score are good, while its changes correlate well with those perceived by the patients themselves. We consider that it can be used as another element to estimate at hospital admission, the degree of support they will require upon discharge. (AU)

RESUMO

In this paper, two new general families of distributions supported on the unit interval are introduced. The proposed families include several known models as special cases and define at least twenty (each one) new special models. Since the list of well-being indicators may include several double bounded random variables, the applicability for modeling those is the major practical motivation for introducing the distributions on those families. We propose a parametrization of the new families in terms of the median and develop a shiny application to provide interactive density shape illustrations for some special cases. Various properties of the introduced families are studied. Some special models in the new families are discussed. In particular, the complementary unit Weibull distribution is studied in some detail. The method of maximum likelihood for estimating the model parameters is discussed. An extensive Monte Carlo experiment is conducted to evaluate the performances of these estimators in finite samples. Applications to the literacy rate in Brazilian and Colombian municipalities illustrate the usefulness of the two new families for modeling well-being indicators.

RESUMO

Objetivo: comparar los resultados funcionales y de calidad de vida, y algunos indicadores de calidad y satisfacción, entre dos estrategias de cuidados posoperatorios de prótesis total de rodilla: 1) Cuidados protocolizados brindados por la Unidad de Rehabilitación del Hospital Italiano (URED) para pacientes que residen en CABA; 2) Cuidados habituales brindados por el sistema tercerizado de rehabilitación kinésica. Materiales y métodos: cohorte prospectiva de pacientes que fueron sometidos a una cirugía de reemplazo articular de la rodilla en el Hospital Italiano. Fueron evaluados mediante cuestionarios de funcionalidad y calidad de vida percibida, y goniometría, a los 45 días, por kinesiólogos entrenados. Resultados: se incluyeron 81 pacientes en el grupo de cuidados protocolizados y 28 en el de cuidados habituales. Se observaron diferencias estadísticamente significativas en todas las variables evaluadas y destacamos la relevancia clínica de que solamente el 2,43% de los pacientes atendidos en la URED continuaban usando andador a los 45 días frente al 35,71% de los que habían sido atendidos con los cuidados habituales (p = 0,004), así como la menor proporción de pacientes con déficit de flexión (2,47% vs. 46%, respectivamente; p < 0,001) y de extensión (18,52 vs. 75%; p < 0,001) en el mismo lapso, requisitos que son importantes para lograr una marcha funcional. Conclusión: un programa de rehabilitación domiciliaria protocolizada y supervisada por kinesiólogos entrenados mostró ser eficaz para una progresión más rápida hacia una marcha independiente con un menor riesgo de déficit de flexión o de extensión a los 45 días.

Objective: to compare functionality and quality of life, and some indicators of patient satisfaction, between two postoperative rehabilitation care following total knee replacement: 1) Protocolized care provided by the Italian Hospital Rehabilitation Unit for patients who live in CABA; 2) Usual care provided by the outsourced rehabilitation system. Materials and methods: prospective cohort of patients who underwent total knee replacement at the Italian Hospital were evaluated using questionnaires of functionality and quality of life at 45 days. Results: 81 patients were included in the protocolized care group and 28 in the usual care group. Statistically significant differences were observed in all the variables evaluated, highlighting clinical relevance that only 2.43% of the patients treated by the URED continued using the walker at 45 days vs 35.71% of those who had been treated with the usual care (p = 0.004); as well as the lower proportion of patients with flexion deficit (2.47 vs. 46%, respectively; p < 0.001) and extension (18.52 vs. 75%; p < 0.001) at the same time. Conclusion: a home protocolarized rehabilitation program supervised by a physical therapist proved to be effective for a quicker progression to an independent walk with lower risks of flexion or extension deficits at 45 days.

RESUMO

INTRODUCTION AND OBJECTIVES: The association between non-alcoholic fatty liver disease and cerebral hemodynamics arises from cardiovascular damage mechanisms such as endothelial dysfunction, arterial wall increased stiffness, high thickness of the intimate index of the internal carotid artery, left ventricular hypertrophy, left diastolic dysfunction, calcification coronary arteries and increased epicardial fat. The multidirectional relationship between systemic inflammation and lipid metabolism constitutes a common and simultaneous mechanism that causes vascular damage. This study aims to provide insight into the relationship between non-alcoholic fatty liver disease and the function of systemic circulation and cerebral circulation using Doppler ultrasound. PATIENTS AND METHODS: Is an observational, cross-sectional, prospective, comparative study conducted at Medica Sur Hospital. Thirty-five patients were selected consecutively. The patients consulted neurological service for various symptoms without severity criteria, such as vertigo, primary headache and balance disturbances. RESULTS: There is a difference in the variables mean of the right MCA PI (p = 0.023), left MCA PI" (p = 0.004), and left VA PI (p = 0.036) between the control and NAFLD groups. The correlation analysis between these variables and the CAP showed a positive correlation of the three variables with the CAP, "right MCA PI" (r = 0.384), left MCA PI "(r = 0.509) and" left VA PI " (r = 0.551). CONCLUSIONS: This study demonstrates a subclinical process of the middle cerebral artery in subjects with NAFLD, which suggests it may be involved in the disease development and points the need to make decisions for this liver manifestation prevention and treatment.

RESUMO

La cirugía de elevación de seno maxilar se considera como la técnica de aumento óseo más predecible. Sin embargo, no está exenta de complicaciones las cuales deben ser manejadas adecuadamente. Se presenta un caso clínico rehabilitado, con un seguimiento de 3 años, en el cual se realizó un manejo multidisciplinario y resolutivo de complicaciones asociadas a la técnica quirúrgica de elevación de membrana sinusal vía ventana lateral. Frente a una infección postoperatoria, como la presentada en el caso, hay que considerar iniciar un tratamiento antibiótico en el momento adecuado para impedir el agravamiento del cuadro clínico o un cambio de esquema en caso de resistencia antimicrobiana.

Maxillary sinus lift surgery is considered the most predictable bone augmentation technique. However, this procedure is not without complications, which must be handled properly. We present a rehabilitated clinical case, with a 3-year follow-up, in which a multidisciplinary and resolutive management of complications associated with the surgical technique of sinus lift procedure, using lateral window approach, was performed. In case of postoperative infection, such as the one presented in this report, it is necessary to consider starting an antibiotic treatment at the adequate moment to prevent the aggravation of the illness or change the pharmacological treatment in case of antimicrobial resistance.

RESUMO

In the present contribution, we have developed a database, called the FAR-database, where the acronym FAR stands for Fused Aromatic Rings, which presents the results of nuclear independent chemical shifts calculations, NICS(0), NICS(1), NICS(0)ZZ, and NICS(1)ZZ, of 660 neutral benzenoid-PAHs and cyclopenta-fused PAHs. The FAR-database provides NICS data of aromaticity of PAHs that could be used in data science and machine learning. To the best of our knowledge, no such database is available in the literature. The importance of this database lies in its potential to transform data into insight and knowledge. Additionally, a new visual representation of the NICS aromaticity pattern, based on the magnitude of the NICS value, is presented. Nowadays calculations of NICS(0)ZZ or NICS(1)ZZ have become popular methods to evaluate aromaticity of systems. By looking at all the 660 systems in the FAR-database, it becomes evident that NICS(0), NICS(1), and NICS(1)ZZ present similar NICS aromaticity patterns for most of the systems. But the NICS aromaticity patterns found with NICS(0)ZZ in many cases do not agree with the NICS aromaticity patterns found with NICS(0), NICS(1), and NICS(1)ZZ. There are cases where the NICS(0)ZZ aromaticity pattern does not show an aromatic character at all. From XY NICS scan at planes from Z = 0 to Z = 1, it is found that as the Z-height is increased, the π-electron ring current effects are dominant, and the σ-bonding contributions are diminished. Therefore, it is recommended here to compute NICS(1)ZZ instead of NICS(0)ZZ when analyzing NICS of PAHs.

RESUMO

Introduction: Identifying the most effective interventions to reverse the metabolic syndrome can be key in the design of clinical strategies to prevent progression to type 2 diabetes mellitus and cardiovascular disease. Objective: To estimate the effect size of the interventions used for the reversal of metabolic syndrome. Materials and methods: We searched in Embase and Medline databases for randomized clinical trials with an outcome defined as the reversal of the metabolic syndrome diagnosis. We classified the interventions in four dimensions: 1) lifestyle (diet and exercise); 2) pharmaceuticals; 3) a combination of both, and 4) control groups, and we conducted a mixed treatment comparison analysis. Results: Additional to the previous meta-analysis published by Dunkley, et al. in 2012, we dentified two other studies. Lifestyle interventions had 2.61 more chances to achieve the reversal of the metabolic syndrome than the control group, with a credible interval between 1.00 and 5.47. Pharmaceutical treatments showed a 3.39 higher chance of reversing the syndrome compared with the control group, but the credible interval was estimated from 0.81 to 9.99. Lifestyle interventions had 1.59 more chance of reversal than the pharmaceutical treatments. Conclusion: Diet and physical activity-based interventions had a higher probability of effectiveness to reverse a metabolic syndrome diagnosis.

Materials and methods: We searched in Embase and Medline databases for randomized clinical trials with an outcome defined as the reversal of the metabolic syndrome diagnosis. We classified the interventions in four dimensions: 1) lifestyle (diet and exercise); 2) pharmaceuticals; 3) a combination of both, and 4) control groups, and we conducted a mixed treatment comparison analysis. Results: Additional to the previous meta-analysis published by Dunkley, et al. in 2012, we identified two other studies. Lifestyle interventions had 2.61 more chances to achieve the reversal of the metabolic syndrome than the control group, with a credible interval between 1.00 and 5.47. Pharmaceutical treatments showed a 3.39 higher chance of reversing the syndrome compared with the control group, but the credible interval was estimated from 0.81 to 9.99. Lifestyle interventions had 1.59 more chance of reversal than the pharmaceutical treatments. Conclusion: Diet and physical activity-based interventions had a higher probability of effectiveness to reverse a metabolic syndrome diagnosis.

RESUMO

We define a new lifetime model based on compounding the Lindley and Nadarajah-Haghighi distributions. The proposed distribution is very competitive to other lifetime models. Some of its mathematical properties are investigated including generating function, mean residual life, moments, Bonferroni and Lorenz curves and mean deviations. We discuss the estimation of the model parameters by maximum likelihood. We provide a simulation study and two applications to real data for illustrative purposes. We prove empirically that the new distribution yields good fits to both data sets, and it can be a useful alternative for other classical lifetime models.

RESUMO

Abstract 20. The success of tissue engineering in combination with tissue regeneration depends on the behavior and cellular activity in the biological processes developed within a structure that functions as a support, better known as scaffolds, or directly at the site of the injury. The cell-cell and cell-biomaterial interaction are key factors for the induction of a specific cell behavior, together with the bioactive factors that allow the formation of the desired tissue. Mesenchymal Stem Cells (MSC) can be isolated from the umbilical cord and bone marrow; however, the behavior of Dental Pulp Stem Cells (DPSC) has been shown to have a high potential for the formation of bone tissue, and these cells have even been able to induce the process of angiogenesis. Advances in periodontal regeneration, dentin-pulp complex, and craniofacial bone defects through the induction of MSC obtained from tooth structures in in vitro-in vivo studies have permitted the obtaining of clinical evidence of the achievements obtained to date.

Resumen 24. El éxito de la ingeniería de tejidos en combinación con la regeneración de tejidos depende del comportamiento y la actividad celular en los procesos biológicos desarrollados dentro de una estructura que funciona como soporte mejor conocida como andamio o directamente en el sitio de la lesión. La interación célula-célula y célula-biomaterial son factores claves para la inducción a un comportamiento célular específico junto con factores bioactivos que permitan la formación del tejido deseado. Las células troncales mesenquimales (MSCs) pueden ser aisladas del cordón umbilical y de la medula ósea, sin embargo, el comportamiento de las células troncales de pulpa dental (DPSCs) han demostrado tener un alto potencial para la formación de tejido óseo e incluso han logrado inducir el proceso de angiogénesis. Avances en la regeneración periodontal, complejo dentino-pulpar y defectos óseos craneofaciales a travez de la inducción de MSCs obtenidas de estructuras de dientes en estudios in vitro-in vivo han permitido obtener evidencia clínica de los logros obtenidos hasta el momento.
