Fig. 2From: SN38-loaded nanomedicine mediates chemo-radiotherapy against CD44-expressing cancer growthA Expression of CD44 antigen on SW620, HT29, and HCT116 cells determined by flow cytometry. B Relative fluorescent intensity of FITC in SW620, HT29, and HCT116 cells (n = 3). C Viability of SW620, HT29, and HCT116 cells after treated with SN38, SH NPs, and SH/HA NPs at different SN38 concentrations for 48 h (n = 3).*p < 0.05Back to article page
