Figure 6. Histology showing vascular impairment and apoptosis in MCF7-mCherry-luc tumors.
Sections were obtained from a series of mice sacrificed at various times after ATO (8 mg/kg). Hoechst stain shows reduced perfusion 2–6 hrs following ATO and H&E stain shows increased necrosis after 24 hrs. Left column: vascular extent (CD31; green) and perfusion (Hoechst 33342; blue). Middle column: Caspase-3 activity indicating apoptosis. Right column: H&E.
