Abstract
The epidermis, which is the outermost layer of mammalian skin, provides an essential barrier that is essential for maintenance of life. The epidermis is a stratified epithelium, which is maintained by the proliferation of epidermal stem cells (EPSCs) at the basal layer of the epidermis. As a unique cell population characterized by self-renewal and differentiation capabilities, EPSCs ensure the maintenance of adult skin homeostasis and participate in repair of the epidermis after injury. Recently, the utilization of EPSCs for wound healing and tissue regeneration has been attracting increased attention from researchers. In addition, the advances in tissue engineering have increased the interest in applying EPSCs in tissue-engineered scaffolds to further reconstitute injured tissues. In this review, we introduce research developments related to EPSCs, including methods recently used in the culture and enrichment of EPSCs, as well as advanced tools to study EPSCs. The function and mechanism of the EPSC-dermal units in the development and homeostasis of the skin are also summarized. Finally, the potential applications of EPSCs in skin tissue engineering are discussed.

Abstract
Human keratinocyte cultures contain keratinocyte stem cells, and have been involved in significant progress regarding stem cell biology as well as keratinocyte biology. Such cultures have also been applied in cell therapy for extensive severe burns for more than three decades, and in genetic disorders of the skin recently. Human keratinocyte stem cells were firstly characterized as holoclones by ex post clonal analysis, but in situ identification of keratinocyte stem cells is required for clinical applications. Recently, it was demonstrated that human keratinocyte stem cells display a unique rotational motion at early stages of culture, with subsequent dynamic collective motion at later stages. This finding enables image-based identification of keratinocyte stem cells, and noninvasive evaluation of their proliferative capacity, which can be applied for the quality assurance of human keratinocyte cultures. This review summarizes the historical development of human keratinocyte cultures and its applications for cell biology and cell therapy. This article also introduces recent advances in keratinocyte stem cell research with medical relevance and discusses the next-generation of regenerative medicine using human keratinocyte stem cells.

Abstract
Recent advances in wound healing have made cell therapy a potential approach for the treatment of various types of skin defects such as trauma, burns, scars and diabetic leg ulcers. Cultured keratinocytes have been applied to burn patients since 1981. Patients with acute and chronic wounds can be treated with autologous/allograft cultured keratinocytes. There are various methods for cultivation of epidermal keratinocytes used in cell therapy. One of the important properties of an efficient cell therapy is the preservation of epidermal stem cells. Mesenchymal Stem Cells (MSCs) are major regulatory cells involved in the acceleration of wound healing via induction of cell proliferation, angiogenesis and stimulating the release of paracrine signaling molecules. Considering the beneficial effects of MSCs on wound healing, the main aim of the present study is investigating paracrine effects of Adipose-derived Mesenchymal Stem Cell (Ad-MSCs) on cultivation of keratinocytes with focusing on preservation of stem cells and their differentiation process. We further introduced a new approach for culturing isolated keratinocytes in vitro in order to generate epidermal keratinocyte sheets without using a feeder layer. To do so, Ad-MSC conditioned medium was applied as an alternative to commercial media for keratinocyte cultivation. In this study, the expression of several stem/progenitor cell (P63, K19 and K14) and differentition (K10, IVL and FLG) markers was examined using real time PCR on days 7, 14 and 21 of culture in keratinocytes in Ad-MSC conditioned medium. P63 and α6 integrin expression was also evaluated via flow cytometry. The results were compared with control group including keratinocytes cultured in EpiLife medium and our data indicated that this Ad-MSC conditioned medium is a good alternative for keratinocyte cultivation and producing epidermal sheets for therapeutic and clinical purposes. The reasons are the expression of stem cell and differentiation markers and overcoming the requirement for feeder layer which leads to a xenograft-free transplantation. Besides, this approach has low cost and is easier to perform. However, more in vitro and in vivo experiments as well as safety evaluation required before clinical applications.

Abstract
Mesenchymal stem cells (MSCs) have been extensively applied in the field of tissue regeneration. MSCs derived from various tissues exhibit different characteristics. In this study, a cluster of cells were isolated from human ethmoid sinus mucosa membrane and termed as hESMSCs. hESMSCs was demonstrated to have MSC-specific characteristics of self-renewal and tri-lineage differentiation. In particular, hESMSCs displayed strong osteogenic differentiation potential, and also remarkably promoted the proliferation and osteogenesis of rat bone marrow mesenchymal stem cells (rBMSCs) in vitro. Next, hESMSCs were prepared into a cell sheet and combined with a PSeD scaffold seeded with rBMSCs to repair critical-sized calvarial defects in rats, which showed excellent reparative effects. Additionally, ELISA assays revealed that secreted cytokines, such as BMP-2, BMP-4 and bFGF, were higher in the hESMSCs conditioned medium, and immunohistochemistry validated that hESMSCs cell sheet promoted the expression of BMP signaling downstream genes in newly formed bone. In conclusion, hESMSCs were demonstrated to be a class of mesenchymal stem cells that possessed high self-renewal capacity along with strong osteogenic potential, and the cell sheet of hESMSCs could remarkably promote new bone regeneration, indicating that hESMSCs cell sheet could serve as a novel and promising alternative strategy in the management of bone regeneration.
