Figure 1: Identification of BM-MSCs and the profile of lipid level in cholesterol-rich fed rats. Phase contrast microscopy depicted that a few small, bright, round cells were present in the primary culture (a). Phase contrast microscopy revealed that BM-MSCs were characterized as a fibroblast-like spindle-shaped morphology (b). Baseline of serum lipid content before received cholesterol-rich diet did not significantly differ among three groups. Cholesterol-rich diet significantly increased total serum cholesterol (c), and LDL (d) levels after angioplasty in rats. The data were expressed as means ± SEM. per group.* versus normal diet group.
