Plant epidermis development requires not only the initial acquisition of tissue identity, but also the ability to differentiate specific cell types over time and to maintain these differentiated states throughout the plant life. To set-up and maintain differentiation, plants activate specific transcriptional programs. Interfering with these programs can prevent differentiation and/or force diff...

water stress effects on winter and spring leaves anatomy were investigated in experiments conducted at the experimental field of sb university of kerman using five wheat cultivars.xylem and phloem elements diameter and mesophyll, bundle sheath and epidermal cells area were measured in transverse sections prepared from middle parts of the leaves. results showed that significant difference exists...

Chondroitin sulfate (CS)/dermatan sulfate (DS) proteoglycans are abundant on the cell surface and in the extracellular matrix and have important functions in matrix structure, cell-matrix interaction and signaling. The DS epimerases 1 and 2, encoded by Dse and Dsel, respectively, convert CS to a CS/DS hybrid chain, which is structurally and conformationally richer than CS, favouring interaction...

Tissue- and cell-type-specific regulators of alternative splicing (AS) are essential components of posttranscriptional gene regulation, necessary for normal cellular function, patterning, and development. Mice with ablation of Epithelial splicing regulatory protein (Esrp1) develop cleft lip and palate. Loss of both Esrp1 and its paralog Esrp2 results in widespread developmental defects with bro...

OBJECTIVE The purpose of this study was to determine whether amnion-derived cellular cytokine solution (ACCS) could improve the quality of epithelialization and accelerate closure of dermatome-created partial-thickness wounds in normal and streptozotocin-induced diabetic pigs. METHODS Dermatome-created partial-thickness wounds were sealed with wound chambers in healthy and diabetic pigs and w...

BACKGROUND Multinucleated giant cells in the epidermis can either be epithelial or histiocytic. Epithelial multinucleated giant cells are most often associated with herpes virus infections. PURPOSE To review the histologic differential diagnosis of conditions with epithelial and histiocytic multinucleated giant cells-since multinucleated giant cells in the epidermis are not always pathognomon...

The balance between epidermal stemness and differentiation requires regulated spatiotemporal changes regulation of gene expression. One emerging area is that epitranscriptomics (regulated RNA modifications), which offers an additional layer in a spatiotemporal- signal-dependent manner. However, its significance healthy diseased epidermis poorly understood. N6-methyladenosine (m6A) the most abun...
