Figure 4From: Arsenic trioxide inhibits Hedgehog, Notch and stem cell properties in glioblastoma neurospheres Arsenic trioxide treatment inhibits clonogenicity in glioblastoma neurosphere cells. A) Quantification of clonogenicity in equal numbers of single viable HSR-GBM1 and 040821 cells seeded in methylcellulose following 3 days of ATO treatment showed significantly fewer colonies over 100 μM in size. B) Representative images of colonies.Back to article page
