Gap junction protein vital to successful pregnancyScientists studying a critical stage of pregnancy implantation of the embryo in the uterus have found a protein that is vital to the growth of new blood vessels that sustain the embryo. Without this protein, which is produced in higher quantities in the presence of estrogen, the embryo is unlikely to survive.
This is the first study to detail the mechanism by which the steroid hormone estrogen spurs cell differentiation and blood-vessel........Go to the OBGYN news blog (Added on 9/10/2008 8:43:49 PM)
