Abstract

A Method for obtaining amniotic mesenchymal tissue cells (AMTC) and/or chorionic mesenchymal tissue cells (CMTC) comprises a) isolating amniotic membrane and/or chorionic membrane from human placenta and/or separating amniotic and chorionic membrane, a) washing the membrane of step a) to remove contaminants b) cutting the membrane of step b) c) incubating the membrane fragments of step c) in a medium containing dispase for 5 to 15 minutes at 33 to 42° C. d) incubating the composition of step d) in a resting solution for 5 to 15 minute at room temperature e) repeating steps d) and e) 0 to 6 times f) if chorionic membrane is involved peeling the stromal layer from the trophoblastic layer of the chorionic membrane of step e or f) g) digesting the fragments obtained in step e), f), or g) respectively, with collagenase for 1 to 5 hours at 33 to 42° C. h) collecting AMTCs and/or CMTCs from the suspension obtained in step h).
