Effect of TX14(A) on growth of primary Schwann cells. (a) Cells were incubated for 48 h in DMEM with 10% fetal calf serum and bovien pituitary extract (0–84 μg/ml) in the absence (open square) or presence (solid circle) of 50 μM forskolin. (b) Cells were incubated for 48 h in DMEM with 10% fetal calf serum and 0–50 μM forskolin (open squares) or 0–50 nM TX14(A) in the absence (solid circle) or presence (solid square) of 50 μM forskolin.
