The intimate relationship between mother and fetus allows placental mammals to birth live offspring. Compared to our egg-laying ancestors, this evolutionary step affords the fetus greater protection within the mother, and has led to a dramatic expansion in brain development.<\/p>\n\n\n\n
But it might surprise you to know that an ancient retrovirus was, in part, responsible for this breakthrough. <\/p>\n\n\n\n
The syncytiotrophoblast (depicted in the second panel): <\/p>\n\n\n\n
\u2686 A acts as a barrier between the placenta and the maternal tissue.<\/p>\n\n\n\n
\u2686 Contains a protein called syncytin that allows this barrier to form, and which originated from the envelope protein of a retrovirus!<\/p>\n\n\n\n
\u2686 is essential to maintain a close relationship where nutrients and gases can be exchanged, whilst ensuring feto-maternal tolerance and immune suppression.<\/p>\n\n\n\n
\u2686is a multinucleate cell layer of fetal origin.<\/p>\n\n\n\n
