IL10-MSCs had better protective effect on lipid metabolic syndrome and liver function in HFD-fed mice (N = 6 in each group). A The effects of MSCs and IL10-MSCs treatment on serum lipid profiles in HFD-fed mice. B The serum levels of ALT and AST in four groups. MSCs and IL10-MSCs both decreased the high levels of ALT and AST induced by HFD feeding, latter had better decrease. C IL10-MSCs treatment clearly decreased the HFD-induced high level of hepatic TG. D-E H&E and Oil Red O staining of liver sections were observed. HFD feeding led to obvious lipid droplets accumulation and more white vacuoles compared with NCD. MSCs and IL10-MSCs administrations remarkably lessened vacuoles and lipid droplets in liver. Moreover, IL10-MSCs had better protective effect on decreasing vacuoles and lipid droplets accumulation.
