What I always wanted to know but never found any information about is:
Why is an embryo not regarded as foreign tissue to a pregnant mother?
Why does the maternal immune system tolerate it?
Doesn't the embryonic tissue express any antigens/MHCs which could stimulate
the mother's immune answer?
Sorry, I'm no expert in that field (but I have some knowledge of basic
immunology).
I would therefore appreciate any answer or hints to scientific publications.
Thank you in advance.
