Of fundamental importance biologically, the activation of EMT programs has been associated with the acquisition of stem cell (SC) traits by normal and neoplastic cells [35,36].The connection between EMT and SCs was most unexpected, indeed counterintuitive, as it indicated that epithelial SCs express a wide array of mesenchymal markers. Les cellules en TEM perdent leur adhésion cellule-cellule (par une diminution de l'expression des cadhérines) et acquièrent des propriétés adhésives nouvelles vis-à-vis de la matrice extracellulaire (par l'expression d'un nouve… Neurobiology of the Murine Pelage Hair Follicle. The epithelium is one of the five main types of animal tissues; the other four are nerve tissue, connective tissue, muscle tissue, and vascular tissue. You can also find these cells lining the airways and respiratory system, blood vessels, urinary tract, digestive tract and kidneys.Epithelial cells make up the lining of many tissues in the human body.

In recent years, cutaneous epithelial stem cells have attained a genuine celebrity status. Hypoxia and high interstitial fluid pressure in the tumor microenvironment induce a specific type of cell death, linearly patterned programmed cell necrosis (LPPCN), which spatially guides VM and endothelium-dependent vessel networks.

Get unlimited, online access to over 18 million full-text articles from more than 15,000 scientific journals. Further insight into the molecular signaling that triggers and promotes VM formation could improve anti-angiogenic therapeutics. Stem-cell niche refers to a microenvironment, within the specific anatomic location where stem cells are found, which interacts with stem cells to regulate cell fate. We induced colitis in Tgr5ISC–/– mice by administration of dextran sulfate sodium; disease severity was determined based on body weight, colon length, and histopathology analysis of colon biopsies. Administration of cholecystokinin to mice resulted in acute release of BAs into the intestinal lumen and increased proliferation of the intestinal epithelium. discover and read the research Biochemical and Biophysical Research Communications.
