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 8

Comparison of TGF-β and bFGF mean percentage decrease between the preirradiated and postirradiated 25 kGy freeze-dried amnion membrane (FD-AM) and amnion sponge.

		FD-AM	Amnion sponge

FD-AM	TGF-β Δ preirradiated postirradiated 25 kGy	—	0.01^ab
Amnion sponge	bFGF Δ preirradiated postirradiated 25 kGy	0.662^b	—
