We analyzed the size and structure of WAT in the CD24 knock-out (CD24KO) mouse on the diet-induced-obesity prone C57BL/6 background (C57BL/6N Cd24atm1Pjln) when fed a standard chow diet (chow), high-sucrose/low fat diet (HSD), or high-fat/low sucrose diet (HFD). Here, CD24 is linked to obesity disorder.
