Human amniotic mesenchymal cells differentiate into chondrocytes.

Recently, cartilage diseases have been treated by auto- or allogenic chondrocyte transplantation. However, such treatments are limited by the necessity of having a large amount of cells for transplantation, the risk of rejection, and donor shortage. Since the human amnion is immune-privileged tissue suitable for allotransplantation, the potential of human amniotic mesenchymal cells (HAMc) to differentiate into chondrocytes was assessed.
