Abstract:
The elucidation of the tissue-specific profile of expression of the prolactin (PRL) and growth hormone (GH) receptors during embryonic and fetal development in a range of species has provided a new impetus for the delineation of the specific roles of the hormone ligands for these receptors in development. During late gestation, there is a requirement to shift from a phase of predominant cellular proliferation, where placental nutrient supply is a dominant influence on organ and body growth, to one of functional differentiation, which is required for independent homoeostasis after birth. In this review we discuss the interactions between the pre-partum increases in cortisol and thyroid hormones and the synthesis, secretion and actions of fetal PRL and GH. We also review the changes that occur in the tissue-specific expression of the PRL and GH receptors before birth which may play an important role in precocial species in the successful transition of the fetus to extra-uterine life.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
