epithelial stem cells review

Postal 14-740. 4.1). We think that oral mucosal epithelial cell sheet technology to treat LSCD can also be improved, because only 52.8% of the transplanted cornea resulted in improved visual acuity. This finding suggested that the thymic medulla is maintained autonomously by its own stem cells. Cytometry A. Evidence includes results that support the presence of corneal epithelial stem cells at the limbus, as well as the major obstacles to isolating them as pure cell populations. α2β1hi/CD133+ cells exhibit two important attributes of epithelial stem cells: they possess a high in vitro proliferative potential and can reconstitute prostatic-like acini in immunocompromised male nude mice. Epub 2007 Sep 2. EXPERT OPINION: The adjunction of human limbal mesenchymal cells as a support for limbal stem cell primary cultures appears to be of great interest. 2011 Oct 17;52(11):8132-7. doi: 10.1167/iovs.11-7984. Ramalho-Santos M, Willenbring H. On the origin of the term “stem cell”. 2011 Apr;112(4):993-1002. doi: 10.1002/jcb.23028. Epithelial stem cells retain a memory of inflammation. Cultured A well-characterized function of p63 is its maintenance of epithelial stem cell proliferation49–51 (Figure 1B). Part of this review describes the variation in the basement membrane composition between the limbus and the central cornea, to show the importance of the corneal stem cell niche, its structure, and the participation of extracellular matrix (ECM) components in regulating corneal stem cell compartment. Yellow=conjunctival BM. Epithelial Stem Cells: Turning over New Leaves. The Expression and Possible Functions of Tenascin-W During Development and Disease. Today, it is known that the cornea has at least two types of stem cells: limbal epithelial stem cells (LESCs) and corneal stromal stem cells (CSSCs). Epithelial cells line various surfaces of the body, including the skin, blood vessels, organs, and urinary tract. This information may provide potential therapeutic strategies to prevent EMT and trigger CSC growth inhibition and cell death. Burn injuries, especially severe ones, are proving to have devastating effects on the affected patients. Only the basal layer, next to the dermis, contains cells that divide. The current knowledge of stem cell biology in the corneal epithelium, clinical consequences of stem cell deficiency, and therapeutic strategies aimed at reversing stem cell deficiency will be discussed. These processes mostly overlap with the acquirement of stem cell properties in differentiated tumor cells. Would you like email updates of new search results? The extracellular matrix composition and structure may regulate limbal stem cell fate providing information about their position. Stem cells emerged as a concept during the second half of 19(th) century, first as a theoretical entity, but then became one of the most promising research fields in cell biology. Epithelial Ovarian Cancer Stem Cells---A Review . 2019 Jul;184:107-125. doi: 10.1016/j.exer.2019.04.010. Most epithelial tissues self-renew throughout adult life due to the presence of multipotent stem cells and/or unipotent progenitor cells. Nature. As we previously reported, nanopillars and pores are able to sustain human pluripotent stem cells and differentiate pancreatic cells. Most epithelial tissues self-renew throughout adult life due to the presence of multipotent stem cells and/or unipotent progenitor cells. As a p53 family TF, p63 is An asymmetric dividing stem cell would give rise to another stem cell and a transient amplifying basal cell that would migrate to the peripheral cornea when division occurs in the horizontal axis. Our current knowledge of the stem cell population in murine epidermis and small intestinal crypts is reviewed. Epithelial ovarian cancer (EOC) remains the most lethal gynecological cancer in developed countries, indicating the need for further research. The DNA demethylating agent, 5-Azacytidine (5Aza), and histone deacetylase inhibitor, valproic acid (Vpa), can improve the reprogramming efficiencies of pluripotent cells. A: stochastic model shows that every cell has the potential to be the tumor initiator; B: CSC model shows that CSCs originate from normal stem cells (NSCs) through mutations and tumorigenic transformation of several potential pathways including Hh: hedgehog, epithelial-to-mesenchymal transition (EMT), and the reverse process mesenchymal-to-epithelial transition (MET). In this review, we have discussed the studies on ovarian cancer stem cells along with the molecular pathways that could be involved in these cancer stem cells.  |  2007 Dec;85(6):845-60. doi: 10.1016/j.exer.2007.08.020. distinct epithelial stem cell (SC) populations that self-renew and generate cells with unipotent and multipotent differentiation potential (Lee & Tumbar, 2012; Sennett & Rendl, 2012). hAECs are readily available, pose no ethical concerns, and have little risk of tumorigenicity and immunogenicity. From this, the nanoscale patterns would be effective environment for the co-culturing of epithelial and mesenchymal cell types. In this review, we explore the regenerative capacity and mechanisms of various populations of intestinal stem cells (ISCs) in response to ionizing radiation. Molecular markers for corneal epithelial cells in larval vs. adult Xenopus frogs. Fate of corneal epithelial cells separated from limbus in vivo. A number of these cells are stem cells, but the majority are transit amplifying cells. Various nanopatterning techniques have been developed to improve cell proliferation and differentiation efficiency. Currently, human amniotic epithelial cells (hAECs) derived from the amnion exhibit considerable advantages over other stem cells and have drawn much attention from researchers. In particular, pancreatic cancer stem cells (PCSCs) are functionally important during tumor relapse and therapy resistance. Blanpain and Fuchs review how different populations of naturally lineage-restricted epithelial stem cells and committed progenitors can also display remarkable plasticity. Most epithelial tissues self-renew throughout adult life due to the presence of multipotent stem cells and/or unipotent progenitor cells. -. This high cell turnover makes it a very attractive and comprehensive adult organ system for the study of cell proliferation and differentiation. Dermal papilla (DP) cells are recognized as the key inductive mesenchymal player, but the ideal source of receptive keratinocytes for human HF regeneration is yet to be defined. 2, A and B). Part of this review describes the variation in the basement membrane composition between the limbus and the central cornea, to show the importance of the corneal stem cell niche, its structure, and the participation of extracellular matrix (ECM) components in regulating corneal stem cell … We show that differentiated NECs are a suitable model for studying the dynamics of SARS-CoV-2 infection in vitro, and that the immune response from infected NECs is surprisingly limited. Epithelial stem cells are specified during development and are controlled by epithelial-mesenchymal interactions. Recently, human-induced pluripotent stem cells have allowed the generation of minicorneal organoids. They vary in methods of epithelial isolation from limbal biopsy, the use and preparation of AM as the substrate, the expansion medium, the use of airlifting to promote epithelial stratification, and the use of additional feeder layers such as mitomycin C-arrested murine 3T3 fibroblasts, mesenchymal stem cells, or human stromal cells (reviewed in (Tseng et al., 2010)). We present an overview of the PUBMED literature in the field as well as recent work from our laboratories. Notes Rec R Soc Lond. Lung epithelial cell culture developed in parallel to cell culture in general, and tissues from many mammalian species have been used as a source of cells both historically and currently. Understanding cornea homeostasis and wound healing using a novel model of stem cell deficiency in Xenopus. We review literature that collectively suggests that BCs of human airways, like those in the mouse trachea, are a population of long-lived, multipotent classical stem cells. Exp Eye Res. Please enable it to take advantage of the complete set of features! Copyright © 2021 Elsevier B.V. or its licensors or contributors. We provide evidence that they are important in the initiation and progression of airway disease, and a potential point of intervention for future therapies. 2008 May;44(5):469-72. NIH Hair follicle (HF) development and growth are dependent on epithelial-mesenchymal interactions (EMIs). STEM CELLS is read and written by clinical and basic scientists whose expertise encompasses the rapidly expanding fields of stem and progenitor cell biology. Epithelial Stem Cells: Turning over New Leaves Most epithelial tissues self-renew throughout adult life due to the presence of multipotent stem cells and/or unipotent progenitor cells. -, McCulloch EA, Till JE. Despite morphological and functional differences among epithelia, common signaling pathways appear to control epithelial stem cell maintenance, activation, lineage determination, and differentiation. Front Cell Dev Biol. This repair process is carried out by the airway stem and progenitor cells. Epithelial stem cells are specified during development and are controlled by epithelial-mesenchymal interactions. The aim of the present study was to investigate the effect of cell fusion between mesenchymal stem cells and the gastric epithelial cells in tumorigenesis. Cell Stem Cell. This work describes the most important characteristics of adult stem cells, including the experimental criteria used to identify them, and discusses current knowledge that led to the proposal that stem cells existed in different parts of the eye, such as the retina, lens, conjunctiva, corneal stroma, Descemet's membrane, and the subject of this review: the corneal epithelium. STEM CELLS, a peer reviewed journal published monthly, provides a forum for prompt publication of original investigative papers and concise reviews. COVID-19 is an emerging, rapidly evolving situation. COMET has been shown to be successful in restoring the corneal surface with follow-up times of up to 35 months [36][37][38][39][40][41][42][43]. Eye (Lond). [Evolving concepts on limbal stem cells and their niche]. Based on a review, the transplant of limbal stem cells was over 70% successful, and it is thought that this success rate can be increased. We identified stem cells specified for mTEC‐lineage that are generated in the thymic ontogeny and may sustain mTEC regeneration and lifelong central T‐cell self‐tolerance. Review: Corneal epithelial stem cells, their niche and wound healing Federico Castro-Muñozledo From the Department of Cell Biology, Centro de Investigación y de Estudios Avanzados del IPN, México City, México Stem cells emerged as a concept during the second half of 19 th century, first as a theoretical entity, but then became one of the most promising research fields in cell biology. Exp Eye Res. See this image and copyright information in PMC. Organoids, a novel in vitro 3D cell culture technique, derived from stem cells, could provide a bridge between the current preclinical platforms. Stem Cell Awareness Day Virtual Issue; Jobs; Regenerative Medicine. Epithelia in adult mammals exhibit remarkable regenerative capacities owing to the presence of adult stem cells, which self‐renew and differentiate to replace cells lost to normal turnover or injury. Additionally, deregulation of these pathways can lead to human disorders including cancer. Depending on the position of cells at the limbal epithelial crypt, the orientation of the mitotic axis during asymmetric cell division of limbal stem cells could be either vertical or horizontal. Conversely, the stem cell could originate another stem cell and a limbal suprabasal differentiated cell when division takes place following the vertical axis; in this case, loss of contact between one of the daughter cells and the basement membrane would determine the initiation of the differentiation process.
