Figure 5.
Apoptosis of human glioblastoma cell lines induced by STS. IPTP, IPTPvgfp, IPTP4asn, and IPTP24sn cells were treated with 1 
M STS and the relative rate of apoptosis was determined after 24 hours, using acridine orange/ethidium bromide staining. IPTP4asn cells had significantly higher rate of apoptosis (54% of cells), whereas IPTP24sn cells were more resistant to apoptosis (13% of cells). Bars represent mean value of three independent experiments and standard error of the mean (mean
SEM). ***Indicates statistically significant (P<.05) difference compared with the parental IPTP cell line.
