Hormesis and Epidermal Stem Cells

open access: yesDose-Response, 2022
This paper provides an assessment of hormetic dose responses in epidermal stem cells (EpSCs) in animal models and humans, with emphasis on cell proliferation and differentiation and application to wound healing and aging processes.

Programmed Cell Death Progresses Differentially in Epidermal and Mesophyll Cells of Lily Petals. [PDF]

open access: yesPLoS ONE, 2015
In the petals of some species of flowers, programmed cell death (PCD) begins earlier in mesophyll cells than in epidermal cells. However, PCD progression in each cell type has not been characterized in detail.

AQP5 regulates the proliferation and differentiation of epidermal stem cells in skin aging [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2020
The epidermis, the outermost layer of the skin, is the first barrier that comes into contact with the external environment. It plays an important role in resisting the invasion of harmful substances and microbial infections. The skin changes with age and

Conjunctival reconstruction with progenitor cell-derived autologous epidermal sheets in rhesus monkey. [PDF]

open access: yesPLoS ONE, 2011
Severe ocular surface diseases are some of the most challenging problems that the clinician faces today. Conventional management is generally unsatisfactory, and the long-term ocular consequences of these conditions are devastating.

Involucrin in the Epidermal Cells of Subprimates.

open access: yesJournal of Investigative Dermatology, 1989
The protein involucrin is a precursor of the cross-linked envelope that forms during terminal differentiation of the keratinocyte. Most of the human involucrin molecule consists of a segment of homologous repeats of a sequence of 10 amino acids. A similar segment is present in the involucrin of other higher primates, but not in lower animals.

Dendritic epidermal T cells secreting exosomes promote the proliferation of epidermal stem cells to enhance wound re-epithelialization

open access: yesStem Cell Research & Therapy, 2022
Background Efficient re-epithelialization is important for successful skin wound healing. The proportion of epidermal stem cells (EpSCs) and dendritic epidermal T cells (DETCs) determines the extent of wound re-epithelialization, especially in large ...

Serine proteolytic pathway activation reveals an expanded ensemble of wound response genes in Drosophila. [PDF]

open access: yesPLoS ONE, 2013
After injury to the animal epidermis, a variety of genes are transcriptionally activated in nearby cells to regenerate the missing cells and facilitate barrier repair. The range and types of diffusible wound signals that are produced by damaged epidermis

Role of bulge epidermal stem cells and TSLP signaling in psoriasis

open access: yesEMBO Molecular Medicine, 2019
Psoriasis is a common inflammatory skin disease involving a cross‐talk between epidermal and immune cells. The role of specific epidermal stem cell populations, including hair follicle stem cells (HF‐SCs) in psoriasis is not well defined.

Hair follicle epidermal stem cells define a niche for tactile sensation

open access: yeseLife, 2018
The heterogeneity and compartmentalization of stem cells is a common principle in many epithelia, and is known to function in epithelial maintenance, but its other physiological roles remain elusive.

Dynamic shifts in chromatin states differentially mark the proliferative basal cells and terminally differentiated cells of the developing epidermis

open access: yesEpigenetics, 2020
Post-translational modifications on nucleosomal histones represent a key epigenetic regulatory mechanism to mediate the complex gene expression, DNA replication, and cell cycle changes that occur in embryonic cells undergoing lineage specification ...
