A) In vivo representative images of the achievement of the hydrogel conjugated with AM-CM (Gel-CM) in promoting wound healing in db/db mice compaing a control group, a hydrogel alone group (Gel alone), and a Gel-CM group, observed at day 0, day 7, and day 12 post wounding. B) Quantitative analysis of wound closure rate of the three groups at different time points show the markedly greater wound closure rate in the Gel-CM group respect to the others which increased after 12 days.
