The basement membrane acts as a substrate (foundation layer) onto which cells can grow to repair or replace the damaged tissue.
The cells of the epithelial layer produce biological factors and mediators that aid the healing process.
Dehydrated AmnioMatrix is a dry amniotic membrane that has had the epithelial layer of cells removed. This membrane acts as a scaffold onto which new cells can grow once it has been placed on the wound. As it is dry, it is packaged and stored conveniently at room temperature.
Cryopreserved AmnioMatrix is fresh amniotic membrane that is processed and stored frozen at -800C. With this method the epithelial layer of cells is retained as well as the important biological factors and mediators.
