The cell fate commitment of precursor cells that will become trophectoderm cells. [GOC:dph, ISBN:0124020607, ISBN:0198542771]
Trophectodermal (TE) cell fate commitment is a crucial developmental process that occurs during the early stages of mammalian embryogenesis. It involves a series of molecular events that lead to the differentiation of a subset of blastomeres into TE cells, which will ultimately give rise to the placenta.
The process of TE cell fate commitment is initiated by the expression of specific transcription factors and signaling pathways. One of the key transcription factors involved is Cdx2. Cdx2 is a homeobox gene that is expressed in the TE lineage and plays a crucial role in the repression of pluripotency genes and the activation of TE-specific genes.
Another important signaling pathway involved in TE cell fate commitment is the Wnt signaling pathway. Wnt signaling is activated in the TE lineage and promotes the expression of TE-specific genes.
During TE cell fate commitment, blastomeres undergo a series of morphological changes. They become polarized, with the apical side facing the blastocoel cavity and the basal side attached to the inner cell mass (ICM). This polarization is essential for the formation of the TE epithelium, which is a single layer of cells that surrounds the ICM.
The TE epithelium is then responsible for the formation of the placenta. The placenta is a vital organ that provides oxygen and nutrients to the developing embryo and removes waste products. TE cells also contribute to the formation of the chorion, which is the outermost layer of the fetal membranes.
In summary, TE cell fate commitment is a complex process that involves the coordinated expression of specific transcription factors and signaling pathways. It is essential for the formation of the placenta and the development of the embryo. The process of TE cell fate commitment is highly regulated and involves a series of molecular and cellular events that ensure the proper development of the embryo.'
