Wound closure in db/db mice

(A) Representative images of wounds treated with phosphate-buffered saline (PBS), control exosomes (M-Exos), or induced pluripotent stem cell-derived exosomes (iPS-Exos) at day 0, 1, 3, 5, 7, 10, 14, 18, 21, and 28.

(B) Quantification of PBS, M-Exo, or iPS-Exo treatment effects at day 0, 1, 3, 5, 7, 10, 14, 18, 21, and 28. *P < 0.05, until day 7.

(C) The rates of wound healing following different treatments. P < 0.05, compared with the controls.

(D) Representative images of wound healing in the PBS, M-Exos, and iPS-Exos group.
