GelMA/tannic acid hydrogel decorated polypropylene mesh facilitating regeneration of abdominal wall defects

This is the authors' abstract. We don't add key points for this paper.

. In addition, PPM/GelMA/TA could inhibit the growth of bacteria, which is of great significance for preventing postoperative infections. Furthermore, in the repair of full-thickness abdominal wall defects in rats, PPM/GelMA/TA reduced inflammation, promoted macrophage M2 polarization, and collagen deposition and angiogenesis so that does not cause any abdominal adhesion compared with PP mesh. As a result, our PPM/GelMA/TA shows an attractive prospect in the treatment of abdominal wall defect without adhesions.
