Investigation of epithelial differentiation in a mouse wound model (360G-Wellcome-211721_Z_18_Z)

Lipoxygenase (LOX) enzymes are expressed by infiltrating immune cells and are involved in innate immune and inflammatory response, all of which are fundamental processes in wound healing. The overarching aims of this larger body of work is to evaluate the role of 12/15-LOX in the cellular orchestration of wound healing using a murine model. We have induced full thickness (4mm) wounds in wildtype and 12/15-LOX knockout mice, then measured wound closure rates and harvested skin tissue at various time points post wounding and conducted histological evaluation of skin sections. Our initial data has found that in 12/15-LOX knockout skin there is enhanced fibroblast expansion, and a reduced infiltration of macrophages, both of which might be beneficial in chronic wound states where failure in fibroblast proliferation and an overt inflammatory state occur. However chronic wounds also displays deficits in wound re-epithelialisation and given that 12/15-LOX products can inhibit epidermal hyperplasia (by modulating cyclin/CDK signalling), we believe that KO mice might also display an enhanced re-epithelialisation phenotype. Therefore, to test this hypothesis we will explore the rate of re-epithelialisation and the cytokeratin profile of epithelial keratinocytes in KO and wildtype mice at various time points post wounding.
