The apoptotic effect of Bone marrow mesenchymal stem cells-conditioned medium (BMMSCs-CM) on the hepatocellular carcinoma cell line HepG2 using Annexin-Propidium Iodide (PI) stains by flowcytometry. The data shows Annexin-PI measurements of untreated HepG2 cell group (control) (A) and treated HepG2 cell groups with 100% BMMSC-CM for 72 h (B), where the x-axis represents Annexin V-Fluorescein Isothiocyanate (FITC) saining and the y-axis represent PI staining, and the statistical analysis (C). Values are expressed as mean±SD, (n= 3), the treated group (HepG2+BMMSC-CM) was compared to the control group (HepG2). (** P<0.01).
