Wound healing is a dynamicprocesscomprising multiple events, such as inflammation, re-epithelialization, and tissue remodeling. Re-epithelialization phase is characterized by the engagement of several cell populations, mainly of keratinocytes that sequentially go through cycles of migration, proliferation, and differentiation to restore skin functions. Troubles can arise during the re-epithelialization phase of skin wound healing particularly in keratinocyte migration, resulting in chronic non-healing lesions, which represent a serious clinical problem. Over the last decades, the efforts aimed to find new pharmacological approaches for wound care were made, yet almost all current therapeutic strategies used remain inadequate or even ineffective. As such, it is crucial to identify new drugs that can enable a proper regeneration of the epithelium in wounded skin. Here, we have investigated the effects of the fibrinolytic drug mesoglycan, a glycosaminoglycans mixture derived from porcine intestinal mucosa on HaCaT human keratinocytes that were used as in vitro experimental model of skin re-epithelialization. We found that mesoglycan induces keratinocyte migration and early differentiation by triggering the syndecan-4/PKC alpha pathway and that these effects were at least in part, because of the formation of the annexin A1/S100A11 complex. Our data suggest that mesoglycan may be useful as a new pro-healing drug for skin wound care.
