Figure 6 -. eWAT of formerly obese mice maintains elevated numbers of preadipocytes.
CD45−CD31−Sca-1+PDGFRα+ preadipocytes in normal diet (ND), weight loss (WL) and HFD diet (HFD) fed mice were quantified by flow cytometry in (A) eWAT (n = 4 for all conditions) and (B) iWAT (n = 4 for ND and n = 3 for WL and HFD). The quantity of Collagen 1 (Col1+) preadipocytes was determined by intracellular flow cytometry in (C) eWAT (n = 4 for all conditions) and (D) iWAT (n = 4 for ND and n = 3 for WL and HFD). * p < 0.05, *** p < 0.001, significance was only compared for ND versus WL or WL versus HFD (20wk).
