Injectable hydrogel made from antler mesenchyme matrix for regenerative wound healing via creating a fetal-like niche

Figure 2 Effects of hydrogels from the antler reserve mesenchyme matrix on wound healing rate in full-thickness skin defects in rats. A: Experimental procedure; B: Macroscopically observation of the wound healing status; C: Quantification of the wound area using the Image J software according to macroscopical images. Note that the fastest wound healing rate and the smallest scar area were observed in the hydrogels from the antler reserve mesenchyme group. DPW: Days post-wounding; HARM: Hydrogels derived from antler reserve mesenchyme; N-CTRL: Negative control; P-CTRL: Positive control. Mean ± SEM; statistical significance set at ^aP < 0.05, ^cP < 0.001.
