Immunohistochemistry of Canine Hair Follicle Stem Cells (cHFSCs) by using CK15 and CK19
DOI:10.30954/2277-940X.02.2020.4
Abstract:
Adult body harbors powerful reservoir of stem cells that maintains homeostasis by tissue regeneration and in response to disease and injury. Hair follicle is a dynamic mini organ supporting important biological functions of the body in maintaining homeostasis and skin tissue self-renewal. This study was carried out with the objective of finding the adult stem cells in canine hair follicular tissue. To conduct this study, adult canine skin samples (n=12) irrespective of breed and sex were collected. To characterize the hair follicle stem cells, paraffin sections of canine hair follicles were immunostained with positive hair follicle stem cell markers like Anti- cytokeratin 15 (CK15) and Anti-cytokeratin 19 (CK19) and FITC conjugated and HRP conjugated secondary antibodies were used. Immunoreactivities for CK15 and CK19 were observed in the bulge/isthmus region of hair follicles in between the infundibulum and suprabulbar regions and occupied most part of the peripheral layer of outer root sheath cell. Immunophenotyping of canine Hair Follicle Stem Cells (cHFSCs) in the bulge region of hair follicle helps in confirmation of in vitro culture of cHFSCs from the bulge region which will be further used for translational research.
