Silicon Alters Leaf Surface Morphology and Suppresses Insect Herbivory in a Model Grass Species

open access: yesPlants, 2020
Grasses accumulate large amounts of silicon (Si) which is deposited in trichomes, specialised silica cells and cell walls. This may increase leaf toughness and reduce cell rupture, palatability and digestion.

A positive regulatory loop between foxi3a and foxi3b is essential for specification and differentiation of zebrafish epidermal ionocytes. [PDF]

open access: yesPLoS ONE, 2007
BACKGROUND: Epidermal ionocytes play essential roles in the transepithelial transportation of ions, water, and acid-base balance in fish embryos before their branchial counterparts are fully functional.

Developmental patterning of sub-epidermal cells in the outer integument of Arabidopsis seeds. [PDF]

open access: yesPLoS ONE, 2017
The seed, the reproductive unit of angiosperms, is generally protected by the seed coat. The seed coat is made of one or two integuments, each comprising two epidermal cells layers and, in some cases, extra sub-epidermal cell layers. The thickness of the

Silicon location through backscattered electron imaging and X-ray microanalysis in leaves of Cyperus ligularis L. and Rhynchospora aberrans C. B. Clarke (Cyperaceae) Localização de sílica por elétrons retroespalhados em folhas de Cyperus ligularis L. and Rhynchospora aberrans C. B. Clarke (Cyperaceae)

open access: yesActa Botânica Brasílica, 2012
The Cyperaceae show the ability to incorporate silicon by depositing colloidal silica, which is recorded by the occurrence of projections in the form of cones, in inner tangential walls of some epidermal cells or "silica cells". Leaves of C.

Both Wnt signaling and epidermal stem cell-derived extracellular vesicles are involved in epidermal cell growth

open access: yesStem Cell Research & Therapy, 2020
Millions suffer from skin diseases. Functional interfollicular epidermal stem cells are needed in skin therapy or drug screening in vitro. We obtained functional interfollicular epidermal stem cells with intact stemness and cell junctions by treating ...

DNA-damage induced cell death in yap1;wwtr1 mutant epidermal basal cells

open access: yeseLife, 2022
In a previous study, it was reported that Yap1 and Wwtr1 in zebrafish regulates the morphogenesis of the posterior body and epidermal fin fold (Kimelman et al., 2017).

Epidermal Stem Cells

open access: yesJournal of Investigative Dermatology, 1983
Stem cells are by definition present in all self-renewing tissues and are believed to play a central role in cell growth and differentiation. Existing evidence suggests that a subpopulation of epidermal basal keratinocytes represents stem cells; however, these cells have never been positively identified.

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.
