Question: Why does a mother's body not reject a foetus?

 chuchoteur - Tue Jul 29, 2003 7:01 pm

I was just wondering if anybody had the medical reason for which a mother's body and immunity system does not reject it's own foetus as a foreign body, such as in an organ transplant?

This is a quite normal to wonder as you :)
Here is possible answer that I learnt while studying autograft rejection. There are five different antibodies in human function at different level, although to control infection. Antibody that involved in graft rejection can not cross placental barrier. Remember plancental barrier is not foreign matter unlike fetus that's protected by placental barrier
