Biopolymers for wound therapy deliver stem cells to improve healing (Phys.org)

NUS researchers have discovered a method to fabricate a biologic interpenetrating network (IPN) hydrogel using applied rheology. Hydrogels are three-dimensional networks of crosslinked polymers. However, current hydrogel wound dressings are made up of synthetic polymers that are biologically inert and do not drive hosts' biology toward wound healing. Such treatment modality is particularly paradoxical for severe wounds where exogeneous…
