Unveiling SerpinB3: A Pioneering Protein in Wound Healing

SerpinB3 has emerged as a key mediator of skin repair and may change how clinicians approach chronic wounds, with potential to accelerate re-epithelialization in slow-to-heal lesions.

The protein promotes keratinocyte migration and proliferation, influences fibroblast activation, and remodels the extracellular matrix. Reported findings also describe shifts in the wound immune milieu consistent with reduced adhesion and enhanced epidermal cell motility — cellular behaviors that together suggest a route to faster re-epithelialization.

In preclinical models, supplemental SerpinB3 accelerated wound closure in vitro and in vivo. Primary endpoints were rate and completeness of epithelial coverage, with improvements attributed to increased cell migration and more organized collagen. Effect sizes were reported as comparable to epidermal growth factor in the same settings; overall, efficacy is robust in controlled models but remains limited to preclinical data.

Clinically, SerpinB3's biological profile maps to chronic wound types marked by impaired epithelial migration and disordered matrix repair — notably diabetic foot ulcers, venous leg ulcers, selected pressure injuries, and certain hard-to-heal surgical sites. Patient phenotypes most likely to benefit include individuals with persistent poor re-epithelialization, biofilm-associated nonhealing wounds, or limited mobility that impairs local tissue recovery.
