The Influence of the Preservation Method and Gamma Irradiation Sterilization on TGF-β and bFGF Levels in Freeze-Dried Amnion Membrane (FD-AM) and Amnion Sponge

Table 1

Comparison of TGF-β and bFGF levels in the preirradiated and postirradiated freeze-dried amnion membrane (FD-AM) with the amnion sponge.
