RESUMO
Although the embryo has a genetic program of its own development in order that development and embryonic differentiation take place, as well as normal gestation, a series of coordinated interactions between embryo and the mother, should be established; which are mediated by chemical messengers, autocrine, paracrine and endocrine. In this study, hormonal participation and regulating factors of implantation, and the feto-placental unit development, are analyzed.

The study included 180 healthy children distributted into age groups from newborns to 16 years of age. The subpopulations of early E and EAC (T and B) rosette forming lymphocytes were determined. It was found that the main difference is placed in percentual mean values of the newborn where the value of T lymphocytes is less than for the rest of the ages studied, remaining stable beginning at the age of one year. In newborns, the values of B lymphocytes are greater; later, they drop but remain stable also since the age of one.
