Additional file 1: Supplementary Fig. 1. Light treatment prevents the onset of senescence in ASCs A-C. The expression of p16, p21, and p53was assessed by qPCR at P3 and P5 AQin ASCs from high fat dietfed C57BL/6 J mice. NFD-P3 as compared a control. E Representative images of SA-β-galactosidase-positive cells. F Senescence was evaluated in terms of SA-β-galactosidase activity and expressed as the ratio of cells protein. Scale bar: 50 μm.
