Establishment of a model for investigating the in vitro differentiation of mesenchymal stem cells from umbilical cord blood into keratinocytes: an approach to study the biology of the skin

Abstract

The human skin is essential for life, isolating the organic components of the external environment. Human skin consists essentially of three layers: the epidermis, the dermis and subcutaneous tissue. The epidermal cells, keratinocytes, are constantly renewed, however, certain pathological conditions such as psoriasis, can affect the proliferation and differentiation of these cells. Different approaches have been proposed for studying events involved in differentiation of keratinocytes. In this context, stem cells emerges, whose potential for self renewal and the ability to generate distinct cell lines with different functions have allowed research on the therapeutic applications of these cells, and the study of different biological processes. An important source of stem cells is represented by the human umbilical cord blood (UCB), formed by hematopoietic and non hematopoietic (mesenchymal) components. It has been shown that mesenchymal stem cells (MSCs) in UCB are capable of differentiating into cell types such as neurons, hepatic, endothelial and muscle cells both in vitro and in vivo. Considering these results and the fact that differentiated keratinocytes from epithelial stem cells are considered difficult to isolate, we are interested in to assess the potential of differentiation of MSC from UCB into keratinocytes, and to study some molecular events involved in this process as the expression of epidermal cell specific markers (p63, cytokeratins 5 and 10), and the expression and activity of different proteases, including kallikreins 5, 6 and 7. In addition to medical therapy, the development of protocols of differentiation of stem cells into keratinocytes may provide useful tools for studying the biology of the skin using in vitro models.
