Phoebe sheareri is an excellent roadside tree with a wide distribution range and high ornamental value. Excessive moisture can affect the external morphology, microstructure, ultrastructure of leaf. Little known at present regarding leaf structure P. under waterlogging stress. In this paper, morphology leaves, microstructure epidermis, mesophyll cells seedlings stress drainage were dynamically ...

The TAF4 subunit of transcription factor TFIID was inactivated in the basal keratinocytes of foetal and adult mouse epidermis. Loss of TAF4 in the foetal epidermis results in reduced expression of the genes required for skin barrier function, leading to early neonatal death. By contrast, TAF4 inactivation in adult epidermis leads to extensive fur loss and an aberrant hair cycle characterised by...

In certain animals, in addition to the protoplasmic fibrils of the stratum filamentosum that are present normally in human epidermis, there are well developed fibrils in the cells of the stratum germinativum. These fibrils are present in the human epidermis only under conditions of increased cell activity. These fibrils, that are prominent in the stratum germinativum of human epidermis under co...

There are only a few cells in the plant kingdom that are as exaggerated in their size or composition as cotton fibers. It is precisely their highly elongated structure and exceptional chemical make-up that establishes cotton fiber as an ideal model for studies of plant cell elongation and cell wall biogenesis. Cotton fibers are unicellular, therefore cell elongation can be evaluated independent...

The epidermis is a spatially arranged tissue of different keratinocytes consisting stem cells, proliferating and differentiating cells. However, the mechanisms regulators arrangement remain unknown. Here, we show that serum starvation induces spontaneous pattern formation in keratinocytes.When were cultured beyond confluence, areas with densely clustered cells those sparsely distributed appeare...

the body and the environment. The main epidermal cell type is an epithelial cell, the keratinocyte.The major structures of the epidermis are the interfollicular epidermis (IFE), hair follicles (HFs), sweat glands, and sebaceous glands (SGs). In human epidermis, the sweat glands are present in both hair-bearing and hairless regions, whereas in mouse epidermis, the sweat glands are restricted to ...
