Hyaluronic acid/mildly crosslinked alginate hydrogel as an injectable tissue adhesion barrier

Although hyaluronic acid (HA) has been conventionally utilized as a tissue adhesion barrier material, its rapid clearance in the body still remains as a big challenge in the clinical practice. In this study, we prepared a hydrogel of HA embedded in mildly crosslinked alginate (HA/mcALG hydrogel), which is injectable, easily covers injured tissues, and remains stably at the applied site during wound healing (by muco-adhesive HA embedded in the...
