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.

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

Granulocyte-activating mediators (GRAM) [PDF]

open access: yes, 1987
In the present study we investigated the capability of human epidermal cells to generate granulocyte-activating mediators (GRAM). It could be shown that human epidermal cells as well as an epidermoid carcinoma cell line (A431) produce an epidermal cell ...

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).

Update on HER-2 as a target for cancer therapy: alternative strategies for targeting the epidermal growth factor system in cancer [PDF]

open access: yes, 2001
The epidermal growth factor (EGF) family of ligands and receptors interact to influence cell division, differentiation and motility. Much evidence supports their importance in causing and sustaining cell transformation in model systems and in human ...

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.

Calcium binding activity of the epidermal growth factor-like domains of the apicomplexan microneme protein EtMIC4 [PDF]

open access: yes, 2005
Microneme proteins are secreted from apicomplexan parasites during invasion of host cells and they play crucial roles in parasite-host cell adhesion.

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.
