Abstract
Epidermal adult stem cells (EpiASCs) have the potential for unlimited proliferation and differentiation, however, the ability of these stem cells to activate corneal genetic programs in response to corneal stroma stimulation needs to be further validated. Herein, a feasible strategy was developed to reconstruct the damaged corneal surface in a goat model with total limbal stem cell deficiency (LSCD) by transplanting EpiASCs, which had been explanted and cultured from the skin of an adult ram goat and were then purified by selecting single cell-derived clones and cultivating them on a denuded human amniotic membrane (HAM). These artificial tissues were then successfully transplanted into ewe goats with total LSCD. Binding of EpiASCs to the base membrane of an EpiASCs-HAM-Sheet (EHS) indicated their proliferating status. After transplantation, the EpiASCs could survive in the host tissue and they reconstructed the damaged ocular surface of total LSCD. The crystal reconstructed corneal epithelium expressed CK3 and Pax-6 similar to normal corneal epithelium and expressed the Sry gene after transplantation. These results demonstrated that EpiASCs could be induced to differentiate into corneal epithelial cell types in a corneal microenvironment and had the ability to activate corneal genetic programs. This work offer a foundation for promoting tissue-engineered cornea into clinical application.

Abstract
For decades, researchers have been fascinated by the strategy of using cell therapy for bone defects; some progress in the field has been made. Owing to its ample supply and easy access, skin, the largest organ in the body, has gained attention as a potential source of stem cells. Despite extensive applications in skin and nerve regeneration, an increasing number of reports indicate its potential use in bone tissue engineering and regeneration. Unfortunately, few review articles are available to outline current research efforts in skin-based osteogenesis. This review first summarizes the latest findings on stem cells or progenitors in skin and their niches and then discusses the strategies of skin cell-based osteogenesis. We hope this article elucidates this topic and generates new ideas for future studies.

Abstract
The therapeutic potential of multipotent stromal cells (MSCs) largely depends on the isolation and expansion methods used. In this study, we propose a laminin-based technique to select and enrich for MSCs isolated from the mouse testis. Primary cell cultures were prepared from juvenile mouse testes and the capacity to generate colony forming units together with population doubling time (PDT) during expansion were determined. The identity of MSCs was assayed using reverse transcription-polymerase chain reaction (RT-PCR) and flow cytometry for the active expression of cell surface markers, such as CD44, CD73, and CD29; absence of the CD45 hematopoietic cell marker; and in vitro differentiation of the cells into osteoblasts and adipocytes. Testis-derived MSCs (tMSCs) displayed self-renewal properties and in the early passages, exhibited high proliferation patterns with an average PDT of 44.1 hours. The lack of Vasa expression implied that the tMSCs were not of germ cell origin. The RT-PCR data, which were confirmed by immunophenotyping, revealed high expression of CD44 and the absence of CD45 expression in tMSCs. The strong Alizarin Red stain in tMSCs that were stimulated into making bone cells was indicative of the presence of calcium-producing cells (osteoblasts). Likewise, the adipogenic potential of tMSCs was demonstrated based on Oil Red O staining of lipid vacuoles in differentiated cells. Loss of fibroblast-like morphology in late passage cells along with the increase in PDT and the decrease in the mRNA levels of CD73 and CD29 suggested that the tMSCs developmental program is reformed at this stage.

Abstract
OBJECTIVES Adult stem cells (ASCs) have great potential for tissue regeneration; however, comparative studies of ASCs from different niches are required to understand the characteristics of each population for their potential therapeutic uses. RESULTS We compared the proliferation, stem cell marker expression, and differentiation potential of ASCs from bone marrow, skin dermis, and adipose tissue. ASCs from bone marrow and skin dermis showed 50-100 % increased proliferation in comparison to the ASCs from adipose tissues. Furthermore, ASCs from each stem cell niche showed differential expression of stem cell marker genes, and preferentially differentiated into cell types of their tissue of origin. CONCLUSION Different characters of each ASC might be major factors for their effective use for therapeutics and tissue regeneration.

Abstract
Adult skin stem cells are recognized as potential therapeutics to rejuvenate aged skin. We previously demonstrated that human dermal stem/progenitor cells (hDSPCs) with multipotent capacity could be enriched from human dermal fibroblasts using collagen type IV. However, the effects of hDSPCs on cellular senescence remain to be elucidated. In the present study, we investigated whether conditioned medium (CM) collected from hDSPC cultures (hDSPC-CM) exhibits beneficial effects on senescent fibroblasts. We found that hDSPC-CM promoted proliferation and decreased the expression level of senescence-associated β-galactosidase in senescent fibroblasts. In addition, p53 phosphorylation and p21 expression were significantly reduced in senescent fibroblasts treated with hDSPC-CM. hDSPC-CM restored the expression levels of collagen type I, collagen type III, and tissue inhibitor of metalloproteinase, and antagonized the increase of matrix metalloproteinase 1 expression. Finally, we demonstrated that hDSPC-CM significantly reduced reactive oxygen species levels by specifically up-regulating the expression level of superoxide dismutase 2. Taken together, these data suggest that hDSPC-CM can be applied as a potential therapeutic agent for improving human aged skin.

Abstract
Cell therapy using adult stem cells has emerged as a potentially new approach for the treatment of various diseases. Therefore, it is an essential procedure to maintain the stemness of adult stem cells for clinical treatment. We previously reported that human dermal stem/progenitor cells (hDSPCs) can be enriched using collagen type IV. However, hDSPCs gradually lose their stem cell properties as in vitro passages continue. In the present study, we developed optimized in vitro culture condition to improve the stemness of these hDSPCs. To evaluate whether the stemness of hDSPCs is well sustained in various culture conditions, we measured the expression levels of SOX2, NANOG, and S100B, which are well-known representative dermal progenitor markers. We observed that hDSPCs grown in three-dimensional (3D) culture condition had higher expression levels of those markers compared with hDSPCs grown in two-dimensional (2D) culture condition. Under the 3D culture condition, we further demonstrated that a high glucose (4.5 g/L) concentration enhanced the expression levels of the dermal progenitor markers, whereas O(2) concentration did not affect. We also found that skin-derived precursor (SKP) culture medium was the most effective, among various culture media, in increasing the dermal progenitor marker expression. We finally demonstrated that this optimized culture condition enhanced the expression level of human telomerase reverse transcriptase (hTERT), the proliferation, and the multipotency of hDSPCs, an important characteristic of stem cells. Taken together, these results suggested that this novel in vitro culture condition improves the stemness of hDSPCs.

Abstract
Adult skin stem cells are considered an attractive cell resource for therapeutic potential in aged skin. We previously reported that multipotent human dermal stem/progenitor cells (hDSPCs) can be enriched from (normal human dermal fibroblasts (NHDFs) using collagen type IV. However, the beneficial effects of hDSPCs on aged skin remain to be elucidated. In the present study, we analyzed the growth factors secreted from hDSPCs in conditioned medium (CM) derived from hDSPCs (hDSPC-CM) and found that hDSPCs secreted higher levels of bFGF, IGFBP-1, IGFBP-2, HGF, VEGF and IGF-1 compared with non-hDSPCs. We then investigated whether hDSPC-CM has an effect on ultraviolet A (UVA)-irradiated NHDFs. Real-time RT-PCR analysis revealed that the treatment of UVA-irradiated NHDFs with hDSPC-CM significantly antagonized the UVA-induced up-regulation of the MMP1 and the UVA-induced down-regulation of the collagen types I, IV and V and TIMP1 mRNA expressions. Furthermore, a scratch wound healing assay showed that hDSPC-CM enhanced the migratory properties of UVA-irradiated NHDFs. hDSPC-CM also significantly reduced the number of the early and late apoptotic cell population in UVA-irradiated NHDFs. Taken together, these data suggest that hDSPC-CM can exert some beneficial effects on aged skin and may be used as a therapeutic agent to improve skin regeneration and wound healing.

Abstract
Adult stem cells from the dermis would be an attractive cell source for therapeutic purposes as well as studying the process of skin aging. Several studies have reported that human dermal stem/progenitor cells (hDSPCs) with multipotent properties exist within the dermis of adult human skin. However, these cells have not been well characterized, because methods for their isolation or enrichment have not yet been optimized. In the present study, we enriched high side scatter (SSC(high))-hDSPCs from normal human dermal fibroblasts using a structural characteristic, intracellular granularity, as a sorting parameter. The SSC(high)-hDSPCs had high in vitro proliferation properties and expressed high levels of SOX2 and S100B, similar to previously identified mouse SOX2+ hair follicle dermal stem cells. The SSC(high)-hDSPCs could differentiate into not only mesodermal cell types, for example, adipocytes, chondrocytes, and osteoblasts, but also neuroectodermal cell types, such as neural cells. In addition, the SSC(high)-hDSPCs exhibited no significant differences in the expression of nestin, vimentin, SNAI2, TWIST1, versican, and CORIN compared with non-hDSPCs. These cells are therefore different from the previously identified multipotent fibroblasts and skin-derived progenitors. In this study, we suggest that hDSPCs can be enriched by using characteristic of their high intracellular granularity, and these SSC(high)-hDSPCs exhibit high in vitro proliferation and differentiation potentials.
