(B) SMMC-7721 cells were incubated with (b,d) or without (a,c) 5-Fu (62.5 μg/ml) for 36 h were stained by the TUNEL method to reveal DNA strand breaks indicative of apoptosis. (a) (b) bright field micrographs corresponding to (c) and (d), respectively. (c)(d), micrographs taken with fluorescent microscopy (400×)
