• pathogens
  • The epidermis layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through transepidermal water loss. (wikipedia.org)
  • layer
  • The epidermis layer is one of three integrated layers of the skin. (innerbody.com)
  • In the 11th week of EGA, the basal layer produces a new intermediate cell layer between itself and the periderm which marks the beginning of stratification and more complicated differentiation of the epidermis. (hindawi.com)
  • The process by which cells in this layer are formed from cells in deeper layer of epidermis and then filled with keratin and moved to the surface is called as KERATINIZATION. (scribd.com)
  • The epidermis is also the thinnest layer, responsible for protecting you from the harsh environment. (lymphedemapeople.com)
  • The epidermis is an important surface tissue of plants that lack lateral meristems, and is commonly only a single cell-layer thick. (fsu.edu)
  • The outermost part of the epidermis is composed of stratified layers of flattened cells, that overlies a basal layer (stratum basale) composed of columnar cells arranged perpendicularly. (wikipedia.org)
  • Most of the barrier functions of the epidermis localize to this layer. (wikipedia.org)
  • The epidermis of a more complex invertebrate is just one layer deep, and may be protected by a non-cellular cuticle. (wikipedia.org)
  • The epidermis (from the Greek ἐπιδερμίς, meaning "over-skin") is a single layer of cells that covers the leaves, flowers, roots and stems of plants. (wikipedia.org)
  • Most plants have an epidermis that is a single cell layer thick. (wikipedia.org)
  • A keratinocyte is the predominant cell type in the epidermis, the outermost layer of the skin, constituting 90% of the cells found there. (wikipedia.org)
  • Epithelium
  • This pattern of staining changes completely upon metamorphosis: the PAS-positive cells, specific to the tadpole epidermis disappear, and the mitochondria-rich (MR) cells in the adult skin epithelium react with polyclonal anti-band 3 antibody. (biomedsearch.com)
  • Eumetazoa have a cavity lined with a similar epithelium, the gastrodermis, which forms a boundary with the epidermis at the mouth. (wikipedia.org)
  • Sponges have no epithelium, and therefore no epidermis or gastrodermis. (wikipedia.org)
  • pores
  • Preliminary research also indicates S. epidermidis is universally found inside affected acne vulgaris pores, where Propionibacterium acnes is normally the sole resident. (wikipedia.org)
  • proteins
  • The recognition of a number of biomarkers of cell junctions and subsequent availability of specific antibodies at 80's and 90's enabled investigation of the junctional proteins of epidermis using immunohistochemical approaches at light and electron microscopic levels. (hindawi.com)
  • stem
  • Epidermal stem cells reside in the lower part of the epidermis (stratum basale) and are attached to the basement membrane through hemidesmosomes. (wikipedia.org)
  • Practice
  • The normal practice of detecting S. epidermidis is by using appearance of colonies on selective media, bacterial morphology by light microscopy, catalase and slide coagulase testing. (wikipedia.org)
  • Anatomy
  • The epidermis of most leaves shows dorsoventral anatomy: the upper (adaxial) and lower (abaxial) surfaces have somewhat different construction and may serve different functions. (wikipedia.org)
  • migrate
  • Some of the transit amplifying cells continue to proliferate then commit to differentiate and migrate towards the surface of the epidermis. (wikipedia.org)
  • immune
  • Although S. epidermidis is not usually pathogenic, patients with compromised immune systems are at risk of developing infection. (wikipedia.org)
  • functions
  • The epidermis serves several functions: it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients. (wikipedia.org)
