Figure 5. The effects of DMC-BH and DMC on orthotopic glioblastoma growth were analyzed by immunohistochemical staining. (A) The orthotopic glioblastoma growth potential after treatment with 20 mg/kg DMC-BH or DMC treatment was evaluated by Ki67 immunohistochemistry. (B) The orthotopic glioblastoma apoptosis rate after treatment with 20 mg/kg DMC-BH or DMC was analyzed by TUNEL staining.
