Development and Maintenance of Epidermal Stem Cells in Skin Adnexa
International Journal of Molecular Sciences Review Development and Maintenance of Epidermal Stem Cells in Skin Adnexa Jaroslav Mokry * and Rishikaysh Pisal Medical Faculty, Charles University, 500 03 Hradec Kralove, Czech Republic; [email protected] * Correspondence: [email protected] Received: 30 October 2020; Accepted: 18 December 2020; Published: 20 December 2020 Abstract: The skin surface is modified by numerous appendages. These structures arise from epithelial stem cells (SCs) through the induction of epidermal placodes as a result of local signalling interplay with mesenchymal cells based on the Wnt–(Dkk4)–Eda–Shh cascade. Slight modifications of the cascade, with the participation of antagonistic signalling, decide whether multipotent epidermal SCs develop in interfollicular epidermis, scales, hair/feather follicles, nails or skin glands. This review describes the roles of epidermal SCs in the development of skin adnexa and interfollicular epidermis, as well as their maintenance. Each skin structure arises from distinct pools of epidermal SCs that are harboured in specific but different niches that control SC behaviour. Such relationships explain differences in marker and gene expression patterns between particular SC subsets. The activity of well-compartmentalized epidermal SCs is orchestrated with that of other skin cells not only along the hair cycle but also in the course of skin regeneration following injury. This review highlights several membrane markers, cytoplasmic proteins and transcription factors associated with epidermal SCs. Keywords: stem cell; epidermal placode; skin adnexa; signalling; hair pigmentation; markers; keratins 1. Epidermal Stem Cells as Units of Development 1.1. Development of the Epidermis and Placode Formation The embryonic skin at very early stages of development is covered by a surface ectoderm that is a precursor to the epidermis and its multiple derivatives. -
Keratin 19 Regulates Cell Shape and Cell-Cell Adhesion of MCF7 Cells While Maintaining E-Cadherin Localization at the Cell Surface
Keratin 19 regulates cell shape and cell-cell adhesion of MCF7 cells while maintaining E-cadherin localization at the cell surface Welcome to my poster. This is Sarah Alsharif, a PhD student from the biology department. I am glad to present the work our lab has been doing in the breast cancer field. In fact, after lung cancer, breast cancer is the second cause of death in women worldwide (1). It is estimated that every 18 seconds, approximately one new case of breast cancer is documented (2). No one dies due to cancer itself. The death is because of metastasis which takes place when cancer cells leave a breast in which they are formed and reach other sites such as the brain or lung. Our lab is interested in investigating the mechanism behind metastasis of breast cancer. Metastasis is associated with what is called epithelial to mesenchymal transition (EMT), the process characterized by loss of cell to cell adhesion and expression of epithelial markers such as keratin intermediate filament proteins, as you can see in the first three images of cells. Those filaments are keratins and they are critical for the shape and for maintaining mechanical integrity of epithelial cells via cell to cell complexes called desmosomes. Among different keratins, keratin 19 (K19) is highly expressed in many types of cancer including breast cancer, and is correlated with a worse prognosis (3). Consistently, K19 expression has been reported to be significantly higher in metastatic breast cancer tumor cells compared to primary tumors (4). The role of K19 on mechanical properties of cancer cells for cell migration and possible impact on metastasis in breast cancer patients is still unknown. -

Structural and Biochemical Changes Underlying a Keratoderma-Like Phenotype in Mice Lacking Suprabasal AP1 Transcription Factor Function
Citation: Cell Death and Disease (2015) 6, e1647; doi:10.1038/cddis.2015.21 OPEN & 2015 Macmillan Publishers Limited All rights reserved 2041-4889/15 www.nature.com/cddis Structural and biochemical changes underlying a keratoderma-like phenotype in mice lacking suprabasal AP1 transcription factor function EA Rorke*,1, G Adhikary2, CA Young2, RH Rice3, PM Elias4, D Crumrine4, J Meyer4, M Blumenberg5 and RL Eckert2,6,7,8 Epidermal keratinocyte differentiation on the body surface is a carefully choreographed process that leads to assembly of a barrier that is essential for life. Perturbation of keratinocyte differentiation leads to disease. Activator protein 1 (AP1) transcription factors are key controllers of this process. We have shown that inhibiting AP1 transcription factor activity in the suprabasal murine epidermis, by expression of dominant-negative c-jun (TAM67), produces a phenotype type that resembles human keratoderma. However, little is understood regarding the structural and molecular changes that drive this phenotype. In the present study we show that TAM67-positive epidermis displays altered cornified envelope, filaggrin-type keratohyalin granule, keratin filament, desmosome formation and lamellar body secretion leading to reduced barrier integrity. To understand the molecular changes underlying this process, we performed proteomic and RNA array analysis. Proteomic study of the corneocyte cross-linked proteome reveals a reduction in incorporation of cutaneous keratins, filaggrin, filaggrin2, late cornified envelope precursor proteins, hair keratins and hair keratin-associated proteins. This is coupled with increased incorporation of desmosome linker, small proline-rich, S100, transglutaminase and inflammation-associated proteins. Incorporation of most cutaneous keratins (Krt1, Krt5 and Krt10) is reduced, but incorporation of hyperproliferation-associated epidermal keratins (Krt6a, Krt6b and Krt16) is increased. -

Chicken is an important model organism that unites the evolutionary gap between mammals and other vertebrates and provide major source of protein from meat and eggs for all over the world population. However, specific genes underlying the regulatory mechanism of broiler pigmentation have not yet been determined. In order to better understand the genes involved in the mechanism of pigmentation in the muscle tissues of broilers, the Affymetrix microarray hybridization experiment platform was used to identify gene expression profiles at 7 weeks of age. Broilers fed canthaxanthin, natural lutein, and orangeII pigments (100 mg/kg) were used to explore gene expression profiles). Our data showed that the 7th week of age was a very important phase with regard to gene expression profiles. We identified a number of differentially expressed genes; in canthaxanthin, natural lutein, and orangeII, there were 54 (32 upregulated and 22 downregulated), 23 (15 upregulated and 8 downregulated), and 7 (5 upregulated and 2 downregulated) known genes, respectively. -

Glomerular development has been analyzed mainly in mice, whereas analysis of human kidney development has been minimal because of limited access to embryonic kidneys. We previously reported the induction of three-dimensional primordial glomeruli from human induced pluripotent stem (iPS) cells. Here, using transcription activator–like effector nuclease-mediated homologous recombination, we generated human iPS cell lines that express green fluorescent protein (GFP) in the NPHS1 locus, which encodes nephrin, and we show that GFP expression facilitated accurate visualization of nephrin-positive podocyte formation in
