Fluorescent tracing of DB/DB EPCs and DB/+ EPCs. (a) DB/DB EPCs and DB/+ EPCs were labeled with PKH26 before transplantation. (b) After 3 days of treatment, frozen slices were prepared from wounds of three groups of mice and observed under a fluorescence microscope. Red fluorescence of EPCs was visible in the DB/DB EPC-treated group and DB/+ EPC-treated group. No red fluorescence was observed in the control group.
