摘要
Amniotic fluid (AF) contains a heterogeneous population of cells of fetal origin in which stem cells are present. These cells are characterized by the expression of mesenchymal (CD73, CD90, CD105) and neural (Nestin, beta 3-tubulin, NEFH) markers, and also some markers of pluripotency (Oct4, Nanog), and they are capable of differentiating into diverse derivatives in vitro. We have shown that epithelial markers (Keratin 19, Keratin 18, and p63) are expressed in AF stem cells simultaneously with mesenchymal ones. During cloning, colonies of cells with fibroblastoid and epithelioid cells are formed. The status and differentiation potential of stem cells from AF have been discussed.
