Figure 5

Colony formation rates of B16 and 4T1 apoptotic cells induced by ACSs. Cells were cocultured with drugs for 24 h, observed, and counted after Giemsa staining. Control: treatment without materials; PBS: negative control, 100 μL/mL; 5-Fu: positive control, 30 μg/mL; ACS-100: 100 μg/mL; ACS-200: 200 μg/mL; ACS-300: 300 μg/mL.
