Fig. 4. PEDF protected Schwann cells from apoptosis. Rat Schwann cells grown in serum free media with or without PEDF for 5 days then evaluated for apoptosis using TUNEL staining. (A) Percentage of apoptotic Schwann cells cultured without or with 1 nM PEDF. 100% represents 75 cells counted. (B-C) Representative TUNEL staining of Schwann cells cultured without (B) or with PEDF (C).
