Abstract

The skin wounds caused by insults should be treated immediately to restore the functions and integrity. Recent studies suggest that stem cells-based therapies may be applicable in wound healing. Newly defined menstrual blood-derived stem cells (MenSCs) show high rate of cell proliferation and trans-differentiation potency to various cell types. However, MenSCs potential to generate keratinocyte for future therapeutic use of skin lesions has been remained to investigate. We cultivated MenSCs in the presence of isolated foreskin derived-keratinocytes using an indirect co-culture system and evaluated efficiency of this protocol to generate keratinocytes using immunofluorescent staining and Real Time PCR technique. Our results showed that differentiated keratinocytes express epidermal/keratinocytes lineage specific markers such as K14, p63, and involucrin at both mRNA and protein levels. Immunofluorescent staining showed the expression of involucrin and K14 in differentiated cells in contrast to undifferentiated cells. Moreover, mRNA expression levels of K14 (11.1 folds, p = 0.001), p63 (10.23 folds, p = 0.001), and involucrin (2.94 folds, p = 0.001) were higher in differentiated MenSCs compared to non-cocultured cells. Therefore, we firstly presented evidence about differentiation capability of MenSCs into epidermal/keratinocytes lineage. Considering the advantages of MenSCs such as great accessibility, these stem cells are promising for stem cells-based therapies of skin defects. © 2017 International Alliance for Biological Standardization
