Abstract

A method of preparing a decellularized placental membrane is provided. The method comprises removing cells from a pre-decellularized placental membrane comprising an amnion layer and a chorion layer to produce a decellularized placental membrane without separating the amnion layer from the chorion layer. The pre-decellularized placental membrane is obtained from an amniotic sac, and the decellularized placental membrane comprises the amnion layer and the chorion layer. Also provided is a decellularized placental membrane and a placenta-derived graft comprising the decellularized placental membrane. Further provided are the uses of the decellularized placental membrane or the placenta-derived graft.
