Human Keratinocytes Adopt Neuronal Fates After In Utero Transplantation in the Developing Rat Brain. Cell Transplant 2021; 30:963689720978219. [PMID: 33435710 PMCID: PMC7809298 DOI: 10.1177/0963689720978219] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2019] [Revised: 11/02/2020] [Accepted: 11/12/2020] [Indexed: 11/30/2022] Open
Abstract
Human skin contains keratinocytes in the epidermis. Such cells share their ectodermal origin with the central nervous system (CNS). Recent studies have demonstrated that terminally differentiated somatic cells can adopt a pluripotent state, or can directly convert its phenotype to neurons, after ectopic expression of transcription factors. In this article we tested the hypothesis that human keratinocytes can adopt neural fates after culturing them in suspension with a neural medium. Initially, keratinocytes expressed Keratins and Vimentin. After neural induction, transcriptional upregulation of NESTIN, SOX2, VIMENTIN, SOX1, and MUSASHI1 was observed, concomitant with significant increases in NESTIN detected by immunostaining. However, in vitro differentiation did not yield the expression of neuronal or astrocytic markers. We tested the differentiation potential of control and neural-induced keratinocytes by grafting them in the developing CNS of rats, through ultrasound-guided injection. For this purpose, keratinocytes were transduced with lentivirus that contained the coding sequence of green fluorescent protein. Cell sorting was employed to select cells with high fluorescence. Unexpectedly, 4 days after grafting these cells in the ventricles, both control and neural-induced cells expressed green fluorescent protein together with the neuronal proteins βIII-Tubulin and Microtubule-Associated Protein 2. These results support the notion that in vivo environment provides appropriate signals to evaluate the neuronal differentiation potential of keratinocytes or other non-neural cell populations.

Abstract
Skin-derived precursors (SKPs) have been described as multipotent dermal precursors. Here, we provide a review of the breadth and depth of scientific literature and studies regarding SKPs, accounting for a large number of scientific publications. Interestingly, these progenitors can be isolated from embryonic and adult skin, as well as from a population of dermal cells cultured in vitro in monolayer. Gathering information from different authors, this review explores different aspects of the SKP theme, such as the potential distinct origins of SKPs in rodents and in humans, and also their ability to differentiate in vitro and in vivo into multiple lineages of different progeny. This remarkable capacity makes SKPs an interesting endogenous source of precursors to explore in the framework of experimental and therapeutic applications in different domains. SKPs are not only involved in the skin's dermal maintenance and support as well as wound healing, but also in hair follicle morphogenesis. This review points out the interests of future researches on SKPs for innovative perspectives that may be helpful in many different types of scientific and medical domains.

Abstract
Repopulation of brain circuits by neural precursors is a potential therapeutic strategy for neurodegenerative disorders; however, choice of cell is critical. Previously, we introduced a two-step culture system that generates a high yield of neural precursors from small samples of adult canine skin. Here, we probe their gene and protein expression profiles in comparison with dermal fibroblasts and brain-derived neural stem cells and characterize their neuronal potential. To date, we have produced >50 skin-derived neural precursor (SKN) lines. SKNs can be cultured in a highly replicable fashion and uniformly express a panel of identifying markers. Upon differentiation, they self-upregulate neural specification genes, generating neurons with basic electrophysiological functionality. This unique population of neural precursors, derived from mature skin, overcomes many of the practical issues that have limited clinical translation of alternative cell types. Easily accessible, neuronally committed, and patient specific, SKNs may have potential for the treatment of brain disorders.

Abstract
Skin-derived precursors (SKPs) are remnants of the embryonic neural crest stem cells that reside in the dermis until adulthood. Although they possess a wide range of differentiation potentials, their differentiation into keratinocyte-like cells and their roles in skin wound healing are obscure. The present study aimed to investigate the differentiation of SKPs into keratinocyte-like cells and evaluate their role in healing of third degree burn wounds. To this aim, SKPs were differentiated into keratinocyte-like cells on tissue culture plate and collagen-chitosan scaffold prepared by freeze-drying. Their differentiation capability was detected by real-time RT-PCR and immunofluorescence. Thereafter, they were cultured on scaffold and implanted in a rat model of burn wound. Histopathological and immunohistochemical analyses were employed to examine the reconstituted skin. The research findings revealed that SKPs were able to differentiate along the epidermal lineage and this ability can be enhanced on a suitable scaffold. Additionally, the results indicated that SKPs apparently promoted wound healing process and accelerate its transition from proliferating stage to maturational phase, especially if they were differentiated into keratinocyte-like cells. Regarding the results, it is concluded that SKPs are able to differentiate into keratinocyte-like cells, particularly when they are cultured on collagen-chitosan scaffold. Moreover, they can regenerate epidermal and dermal layers including thick collagen bundles, possibly through differentiation into keratinocyte-like cells.

Abstract
Human skin-derived precursor cells are a multipotent stem cell population that resides within the dermis throughout adulthood. Human skin-derived precursor cells can be isolated, purified, and expanded in large quantities from any patient, in health and disease, and differentiated to mesodermal and ectodermal cell types. Recently, it was also found that they can be directed towards hepatic cells with acquired properties of toxicological relevance. As such, they represent a valuable cell source for the further development of human-relevant in vitro models for the identification and quantification of hepatotoxic compounds. In this chapter, a robust basic methodology to isolate, expand, and differentiate human skin-derived precursor cells into hepatic cells in a sequential and time-dependent way is provided.

Abstract
Human skin-derived precursors (hSKPs) are multipotent somatic stem cells that persist within the dermis throughout adulthood and harbor potential clinical applicability. In this study, we investigated their immunogenicity and immunosuppressive features, both in vitro and in vivo. As such, this study provides a solid basis for developing their future clinical applications. We found that hSKPs express HLA-ABC molecules, but not HLA-DR, rendering them poorly immunogenic. Using a coculture set-up, we could further demonstrate that hSKPs inhibit the proliferation of allogeneic activated T cells and alter their cytokine secretion profile, in a dose-dependent manner. Cotransplantation of hSKP and human peripheral blood leukocytes (PBL) into severe combined immune-deficient mice also showed a significant impairment of the graft-versus-host response 1 week post-transplantation and a drastic increase in survival time of 60%. From a mechanistic point of view, we found that hSKPs require cell contact as well as secretion of soluble inhibitory factors in order to modulate the immune response. The expression/secretion levels of these factors further increases upon inflammation or in the presence of activated T cells. As such, we believe that these features could be beneficial in a later allogeneic clinical setting, because rejection of engrafted allogeneic hSKP might be delayed or even avoided due to their own promotion of a tolerogenic microenvironment.

Abstract
Human skin-derived precursors (hSKP) are postnatal stem cells with neural crest properties that reside in the dermis of human skin. These cells can be easily isolated from small (fore) skin segments and have the capacity to differentiate into multiple cell types. In this study, we show that upon exposure to hepatogenic growth factors and cytokines, hSKP acquire sufficient hepatic features that could make these cells suitable in vitro tools for hepatotoxicity screening of new chemical entities and already existing pharmaceutical compounds. Indeed, hepatic differentiated hSKP [hSKP-derived hepatic progenitor cells (hSKP-HPC)] express hepatic progenitor cell markers (EPCAM, NCAM2, PROM1) and adult hepatocyte markers (ALB), as well as key biotransformation enzymes (CYP1B1, FMO1, GSTA4, GSTM3) and influx and efflux drug transporters (ABCC4, ABCA1, SLC2A5). Using a toxicogenomics approach, we could demonstrate that hSKP-HPC respond to acetaminophen exposure in a comparable way to primary human hepatocytes in culture. The toxicological responses "liver damage", "liver proliferation", "liver necrosis" and "liver steatosis" were found to be significantly enriched in both in vitro models. Also genes associated with either cytotoxic responses or induction of apoptosis (BCL2L11, FOS, HMOX1, TIMP3, and AHR) were commonly upregulated and might represent future molecular biomarkers for hepatotoxicity. In conclusion, our data gives a first indication that hSKP-HPC might represent a suitable preclinical model for in vitro screening of hepatotoxicity. To the best of our knowledge, this is the first report in which human postnatal stem cells derived from skin are described as a potentially relevant cell source for in vitro hepatotoxicity testing of pharmaceutical compounds.

Abstract
Human adult stem cells (hASCs) have become an attractive source for autologous cell transplantation, tissue engineering, developmental biology, and the generation of human-based alternative in vitro models. Among the 3 germ cell layers, the mesoderm is the origin of today's most widely used and characterized hASC populations. A variety of isolated nonhematopoietic mesoderm-derived stem cell populations exist, and all of them show important differences in terms of function, efficacy, and differentiation potential both in vivo and in vitro. To better understand whether the intrinsic properties of these cells contribute to the overall differentiation potential of hASCs, we compared the global gene expression profiles of 4 mesoderm-derived stem cell populations: human adipose tissue-derived stromal cells, human bone marrow-derived stromal cells (hBMSCs), human (fore)skin-derived precursor cells (hSKPs), and human Wharton's jelly-derived mesenchymal stem cells (hWJs). Significant differences in gene expression profiles were detected between distinct stem cell types. hSKPs predominantly expressed genes involved in neurogenesis, skin, and bone development, whereas hWJs and, to some extent, hBMSCs showed an increased expression of genes involved in cardiovascular and liver development. Interestingly, the observed differential gene expression of distinct hASCs could be linked to existing differentiation data in which hASCs were differentiated toward specific cell types. As such, our data suggest that the intrinsic gene expression of the undifferentiated stem cells has an important impact on their overall differentiation potential as well as their application in stem cell-based research. Yet, the factors that define these intrinsic properties remain to be determined.
