Chloroquine inhibits glioblastoma cell proliferation.

<p>U87MG and Gli36ΔEGFR cells were incubated with increasing concentrations of CQ for 7–10 days. At the end of the growth period colonies were fixed, stained and counted. After taking into account the plating efficiency for each cell line, the surviving fraction is the ratio of the number of colonies counted and the initial number of cells plated. Mean ± S.D., n = 3.
