Inhibition of apoptosis in PC12 cells by TS. PC12 cells in serum-free RPMI were plated in collagen-coated plastic dishes in the presence of various reagents for 17 h and stained with DAPI (A) or TUNEL (B). The additions in A were (a) 0.1 μg/ml NGF; (b) no addition; (c) 0.1 μg/ml TS; and (d) 0.2 μg/ml VCNA. Magnification, 1000×. Additions in B were (a) no addition; (b) 0.1 μg/ml NGF; and (c) 0.1 μg/ml TS. Magnification, 400×.
