Abstract: Objective To establish the method of isolation, purification, and identification of human amniotic mesenchymal stem cells (hAMSCs). Methods hAMSCs were isolated from human amniotic membrane by trypsin-collagenase digestion, and cultured in Dulbecco’s modified Eagle’s medinm/F12 medium supplemented with 10% fetal bovine serum. Phenotypic characteristics of these cells were analyzed by means of immunocytochemistry and flow cytometry. Results The cells successfully isolated from human amniotic membrane expressed representative mesenchymal cell surface markers CD44, CD90, and vimentin, but not CD45. Conclusions This study establishes a potential method for isolation of hAMSCs from human amnion,in vitro culture, and identification. The isolated cells show phenotypic characteristics of mesenchymal stem cells.

Key words: amniotic mesenchymal stem cell, cell isolation, cell culture;cell identification
