Abstract:
:Skin-derived tissue cultures are a useful model to study molecular mechanisms of skin renewal and pathogenesis of dermal diseases. Horses often suffer from skin diseases, skin trauma and problems with proper wound healing, which could be improved by in vitro grown keratinocyte grafts. Herein we describe establishment and characterization of equine skin-derived primary cell cultures, using enzymatic and explant methods. The established cell lines of primary equine keratinocytes (peK) maintained high proliferative capacity for over five passages and expressed different epithelial/keratinocyte-specific markers. Characterization of the primary culture was performed in parallel with localization studies of the markers in the skin histological sections, using commercially available antibodies. Relative expression of typical differentiation stage-specific markers was determined in the established cell lines, using RT-qPCR. Basal (proliferating) keratinocytes were the predominant cell type in the established cell lines, but low expression of post-mitotic keratinocyte markers was also detected. Differences in marker expression were observed neither between the peK originating from two different animals nor between the peK established with two different methods (enzymatically or by explanting). The described methods in combination with the suggested characterization and differentiation markers are suitable for establishment of proliferating peK and evaluation of their differentiation status.
