Quantitative analysis of TUNEL and MC in U87 (a), IC (b) and LN229 (c) cells after exposure to JS-K for 48 and 72 h. The induction of MC was determined by counting cells with characteristics described by Roninson et al. Induction of cell death by JS-K was plotted relative to total cell number and show a significant dose- and time-dependent increase in MC compared to apoptosis. Asterisks (*P<0.05, **P<0.01, ***P<0.001) indicate significance between apoptosis and MC with ±s.d. of three independent experiments
