Summary
Chronic non-healing wounds in horses frequently fail to re-epithelialise due to insufficient keratinocyte coverage, presenting a significant clinical challenge in equine practice. Aguiar and colleagues successfully differentiated equine induced pluripotent stem cells (eiPSC) into functional keratinocytes using established differentiation protocols, demonstrating that the approach previously validated in human and murine models could be adapted to equine tissue. The resulting keratinocytes exhibited appropriate morphological and molecular characteristics consistent with mature epidermal cells, confirming successful lineage commitment. These findings open practical avenues for regenerative wound management in horses, potentially offering farriers, veterinarians and wound-care specialists a means to generate autologous keratinocyte grafts for chronic or refractory skin injuries that currently have limited treatment options. Further development toward clinical application will require validation of graft integration, functional performance in natural wound environments, and scalability for routine therapeutic use.
