PTPRC and colitis: To investigate the efficacy of CD73+ cell transplantation in a mouse model of DSS-induced colitis, we initially isolated CD45-CD31-Ter119-CD73+ (CD73+) cells from the subcutaneous white adipose tissue of mice, using fluorescence-activated cell sorting (FACS), and compared them with cMSCs attached to the culture dish (Figure S1 and Figure 1A).
