From: CdTe quantum dots with daunorubicin induce apoptosis of multidrug-resistant human hepatoma HepG2/ADM cells: in vitro and in vivo evaluation

Figure 4

Assay of cell apoptosis rate and morphological images: (A) Detection of apoptotic and normal cells by acridine orange staining. Control cell nuclei, apoptotic nuclei from HepG2/ADM cells ware observed. (B) HepG2/ADM cells detected by flow cytometry using Annexin-V-FITC method. (a) control treatment; (b) 4 × 10-6 mol/L DNR treatment; (c) 4 μM Cdte QDs treatment; and (d) 4 μM Cdte QDs + 4 × 10-6 mol/L DNR for 36 h. (C) Quantitative analysis of apoptotic cells after various treatments shown in (B). *p < 0.05, compared to the control treatment.
