Assessment of cell proliferation of HPMSCs, HPMSCs/NC, and HPMSCs/leptin by CCK-8 assay
HPMSCs/leptin exhibited better cell proliferation, compared with HPMSCs and HPMSCs/NC. Data are expressed as mean±standard deviation (SD), n=4. *** P<0.001 compared with other groups. HPMSCs: human placenta-derived mesenchymal stem cells; NC: negative control; CCK-8: cell counting kit-8; OD450: optical density at 450 nm
