 This makes the possibility of rejection of the cells by the recipient tissue less likely.Unlike traditional tissue transplants, where the donor and recipient have to be in complete sync as far as blood type and overall compatibility and even still can show tissue rejection, amniotic epithelial cells can be used and show a higher likelihood of tissue acceptance.Also, amniotic epithelial cells are known to promote natural wound healing as well as the inhibition of angiogenesis, which is the basic conversion of a tumor into malignant cancer.
