Oncostatin m improves cutaneous wound re-epithelialization and is deficient under diabetic conditions
Impaired re-epithelialization characterized by hyperkeratotic non-migratory wound epithelium is a hallmark of non-healing diabetic wounds. In chronic wounds, copious release of oncostatin M (OSM) from wound macrophages is evident. OSM is a potent keratinocyte activator. This work sought to understand the signal transduction pathway responsible for wound-re-epithelialization, the primary mechanism underlying wound closure. Daily topical treatment of full-thickness excisional wounds of C57bl/6 mice with recombinant murine OSM improved wound re-epithelialization and accelerated wound closure by bolstering keratinocyte proliferation and migration.
