RESUMEN

Cultivated meat (CM) offers a sustainable and ethical alternative to conventional animal agriculture, involving cell maturation in a controlled environment. To emulate the structural complexity of traditional meat, the development of animal-free and edible scaffolds is crucial, providing vital physical and biological support during tissue development. The aligned vascular bundles of the decellularised asparagus scaffold were selected to facilitate the attachment and alignment of murine myoblasts (C2C12) and porcine adipose-derived mesenchymal stem cells (pADMSCs). Muscle differentiation was assessed through immunofluorescence staining with muscle markers, including Myosin heavy chain (MHC), Myogenin (MYOG), and Desmin. The metabolic activity of Creatine Kinase in C2C12 differentiated cells significantly increased compared to proliferated cells. Quantitative PCR analysis revealed a significant increase in Myosin Heavy Polypeptide 1 (MYH1) and MYOG expression compared to Day 0. These results highlight the application of decellularised plant scaffold (DPS) as a promising, edible material conducive to cell attachment, proliferation, and differentiation into muscle tissue. To create a CM prototype with biological mimicry, pADMSC-derived muscle and fat cells were also co-cultured on the same scaffold. The co-culture was confirmed through immunofluorescence staining of muscle markers and LipidTOX staining, revealing distinct muscle fibres and adipocytes containing lipid droplets respectively. Texture profile analysis conducted on uncooked CM prototypes and pork loin showed no significant differences in textural values. However, the pan-fried CM prototype differed significantly in hardness and chewiness compared to pork loin. Understanding the scaffolds' textural profile enhances our insight into the potential sensory attributes of CM products. DPS shows potential for advancing CM biomanufacturing.

RESUMEN

Cultured meat has emerged as a promising alternative to conventional meat due to its potential to be healthier, more humane, and sustainable. The development of serum-free media by Messmer et al. and the adaptation of soy protein as edible scaffolds by Ben-Arye et al. highlight innovations in this nascent field.

RESUMEN

Cultured meat (CM) has emerged as a breakthrough technology, which has the potential to minimise future negative impacts associated with the rapidly growing world population; such as serious environmental, sustainability, global public health, and animal welfare concerns. Recently numerous researchers in academia and companies have been putting significant efforts into scientific and translational development in this field. Since various pillars of CM manufacturing hold substantial translational potential, there has been a steady interest in filing patent applications globally in the past decade. For the first time, we have performed a patentometric analysis for cultured meat by highlighting the current patents landscape, determining prolific organisations and geographical locations active in the area, and identifying the overall outlook for the field. In total, > 190 patents published in the English language were collected from 1997 to 2020 for the analysis. Relevant data were extracted from the patents, including technology focus, country of origin, assignees, priority date, cooperative patent classification (CPC) code, to analyse the current patent landscape.
