ABSTRACT:
Transplantation of epithelial stem cells, cultured ex vivo on specifically treated amniotic membrane, yields, with that amniotic membrane, a surgical graft having expanded epithelial stem cells. The method of creating this graft and the graft itself are simple and effective to reconstruct damaged tissue, a preferred example being corneal tissue. The source of the epithelial stem cells can be a very small explant from healthy autologous and allogeneic tissue biopsy. The amniotic membrane is treated such that its extracellular matrix is maintained, but its cells are killed.
