Epidermal Cells Expressing Putative Cell Markers in Nonglabrous Skin Existing in Direct Proximity with the Distal End of the Arrector Pili Muscle

<div>Localization of K15 in the interfollicular epidermis and follicle. Immunofluorescence microscopy showing patterns of phalloidin, expression of <i>α</i>5 integrin, K15, and collagen VII. (a) K15 (red) demonstrates a heterogeneous expression in the basal epidermis and follicular bulge. K15 expression is evident at the distal attachment of the APM (green) in the epidermis. (b) Magnified view of the distal attachment of the APM. K15 (red) expression at the distal APM (green) attachment. (c) Triple immunofluorescence staining for K15 (red), collagen VII (green), and phalloidin (blue) showing K15 expressing cells and cells stained with phalloidin in the basal epidermis at the distal tip of the arrector pili muscle (blue) 100 <i>μ</i>m.</div>
