Many epithelial tissues are characterized by the presence of basal cells which serve the dual roles of self-renewal and of progression through terminal differentiation, to a functional state. Such tissues, when grown in vitro as primary explants, exhibit a characteristic pattern of outgrowth and ...
Epithelial tissue is characterized by each of these traits, except that A) it lacks blood vessels B) it functions in secretion, absorption, and excretion C) epithelial cells are loosely packed and have much intercellular material D) it is anchored to...
thin extracellular layer that lies underneath epithelial cells and separates them from other tissues basement membrane in epithelial tissue, a thin layer of fibrous material that anchors the epithelial tissue to the underlying connective tissue; made up of the basal lamina and reticular lamina ...
What are the functions of epithelium and connective tissue? What is the function of connective tissue? All glands are composed of the same general tissue. What is that tissue? How are cells in the epidermal tissue adapted? Name some of the specialized tissues. ...
One of the most exciting areas of stem cell biology stems from the recent demonstration of the interconvertability of haematopoietic cells and neuronal tissues,34,35 skeletal muscle cells,36 and hepatic stem cells.37,38 This raises the question of whether corneal epithelial stem cells are also ...
psammoma,sand tumor- a tumor derived from fibrous tissue of the meninges or choroid plexus or certain other structures associated with the brain; characterized by sandlike particles teratoma- a tumor consisting of a mixture of tissues not normally found at that site ...
Tissue cells are known to express iRhom1 under basal conditions while immune cells preferentially express iRhom226,35. To get an idea of the expression level in the healthy colon, we performed a bioinformatic analysis of the reported expression data for different colon epithelial tissues using GEN...
cancer of the blood, leucaemia, leukaemia, leukemia - malignant neoplasm of blood-forming tissues; characterized by abnormal proliferation of leukocytes; one of the four major types of cancer sarcoma - a usually malignant tumor arising from connective tissue (bone or muscle etc.); one of the fo...
Intact skin and mucosal barriers are crucial for the maintenance of tissue homeostasis as they protect host tissues from infections, environmental toxins, pollutants and allergens. A defective epithelial barrier has been demonstrated in allergic and autoimmune conditions such as asthma, atopic dermatitis,...
The number and quality of cells in the epithelial sample are most important for the successful initiation of the airway epithelial cell cultures. The highest initial number of primary HAE cells can be obtained from tissues obtained via resection, transplantation or autopsy. However, these procedures ...
