The objective of the authors has been to obtain multilineage-differentiating stress-enduring cells (Muse cells) from primary cultures of dermal fibroblasts, identify their pluripotency, and detect their ability to differentiate into melanocytes. The distribution of SSEA-3-positive cells in human scalp skin was assessed by immunohistochemistry, and the distribution of Oct4, Sox2, Nanog, and SSEA-3-positive cells was determined by immunofluorescence staining. The expression levels of Sox2, Oct4, hKlf4, and Nanog mRNAs and proteins in Muse cells were determined by reverse transcription polymerase chain reaction (RT-PCR) analyses and Western blots, respectively. These Muse cells differentiated into melanocytes in differentiation medium. The SSEA-3-positive cells were scattered in the basement membrane zone and the dermis, with comparatively more in the sebaceous glands, vascular and sweat glands, as well as the outer root sheath of hair follicles, the dermal papillae, and the hair bulbs. Muse cells, which have the ability to self-renew, were obtained from scalp dermal fibroblasts by flow cytometry sorting with an anti-SSEA-3 antibody. The results of RT-PCR, Western blot, and immunofluorescence staining showed that the expression levels of Oct4, Nanog, Sox2, and Klf4 mRNAs and proteins in Muse cells were significantly different from their parental dermal fibroblasts. Muse cells differentiated into melanocytes when cultured in melanocyte differentiation medium, and the Muse cell-derived melanocytes expressed the melanocyte-specific marker HMB45. Muse cells could be obtained by flow cytometry from primary cultures of scalp dermal fibroblasts, which possessed the ability of pluripotency and self-renewal, and could differentiate into melanocytes in vitro.
