TLDR Mesenchymal stem cells help heal wounds by using Cx43 hemichannels to improve tissue repair.
The study identifies a novel mechanism by which mesenchymal stem cells (MSCs) promote wound healing through Cx43 hemichannel-mediated paracrine signaling, primarily involving ATP secretion. This process enhances macrophage polarization, angiogenesis, and fibroblast migration, leading to improved tissue repair. The findings highlight a new role for Cx43 hemichannels in MSC-facilitated tissue repair and suggest a promising therapeutic strategy for clinical applications to enhance wound healing.
