From: Fas induces apoptosis in human coronary artery endothelial cells in vitro
Induction of apoptosis in cultured human coronary artery endothelial cells by purified human TNF-α. Human coronary artery endothelial cells (HCAEC) were incubated with purified recombinant human TNF-α at the indicated concentrations (ng/ml) in serum-free medium. After 20 hours, apoptosis was detected as described in Figure 1. Bars are the mean + S.E.M. of at least three determinations; ** = p < 0.01 versus 0.0 dose by ANOVA and Student-Newman-Keul's test.
