	Ocular Surface Epithelium
		Based on the unique keratin expression pattern of corneal epithelium, we proposed in 1986 that corneal epithelial stem cells reside in the limbus, a previously ignored, transitional zone between cornea and conjunctiva (J Cell Biol 1986).
		The limbal stem cell concept explains why an earlier surgical procedure, in which conjunctival epithelium was used to repair damaged corneal epithelium, was ineffective.
		The new concept led to the introduction of a new surgical procedure called “limbal transplantation” in which limbal stem cells are used to repair a damaged or denuded corneal epithelium.

		In biology and dermatology, epithelium is a tissue composed of a layer of cells.
		Epithelium lines both the outside (skin) and the inside cavities and lumen of bodies.
		A one-cell layer of simple squamous epithelium forms the alveoli of the respiratory membrane, and the endothelium of capillaries, and is a minimal barrier to diffusion.

	Reference.com/Encyclopedia/Squamous epithelium
		A simple squamous epithelium is characterized by the presence of squamous cells which are all in contact with the basement membrane.
		Although this epithelium is referred to as squamous, many cells within the layers may not be flattened; this is due to the convention of naming epithelia according to the cell type at the surface.
		Stratified squamous epithelium is further classified by the presence or absence of keratin at the apical surface.

	Is ablation of the esophageal columnar tissue more likely to induce restoration of squamous epithelium than just acid ...
		Glandular epithelium that lines the distal esophagus is thought to develop as a consequence of metaplastic re-epithelialization of injured or denuded stratified squamous esophageal mucosa.
		The source of the islands of tissue could be the proximal superficial squamous cells that line the ducts of the esophageal cardiac glands [4], persistent microscopic foci of normally-differentiated squamous epithelium within the glandular tissue, or primordial stem cells.
		We hypothesized that squamous epithelium could be restored to areas of columnar mucosa if the established columnar tissue was ablated and the presence of noxious agents was reduced during the time the esophageal epithelium healed [16].

	Exercise 4: Epithelium
		In pseudostratified epithelium, the general appearance is that of several layers, but in reality all of the cells reach the basement membrane, and the epithelium is truly a simple one.
		The epithelium you see here is in a bladder that's contracted (because it's empty...ahhh....).To accommodate this change in organ volume, the lining epithelium has to have extra membrane so that when the bladder is distended, the cells aren't stretched and torn.
		Urinary epithelium is impermeable to water, thanks to large numbers of occluding junctions between the cells.

	Blue Histology - Epithelia and Glands
		Simple cuboidal epithelium occurs in small excretory ducts of many glands, the follicles of the thyroid gland, the tubules of the kidney and on the surface of the ovaries.
		Transitional epithelium is found exclusively in the excretory urinary passages (the renal calyces and pelvis, the ureter, the urinary bladder, and part of the urethra).
		The shape of the cells in the surface layer of a transitional epithelium varies with the degree of distension of the organs whose lumen is lined by this type of epithelium.

	Epithelium (Site not responding. Last check: 2007-11-07)
		Epithelium is one of the four primary tissues (Epithelium, connective, muscle, nervous) found in the human organism.
		Epithelium is subdivided into two types: the first is called a lining epithelium, the second a glandular epithelium.
		The lining epithelium is further divided into two types: the first type is said simple, since it is formed of a single layer of cells; the second type is called stratified.

	Epithelium (Site not responding. Last check: 2007-11-07)
		Epithelium lines the surfaces of the body and is mainly located on the borders between the external and internal environments.
		For example, the epidermis of the skin is ectodermal in origin, the epithelium lining the serous cavities (peritoneum, pleura, pericardium) is derived from mesoderm (and is often referred to as mesothelium), whereas the epithelium lining most of the intestinal tract is endodermal.
		Goblet cells are found scattered in the heterogeneous epithelium of mucous membranes, for example, in the pseudostratified epithelium of the respiratory tract or in the absorptive epithelium of the small and large intestine.

	Are all different types of Barrett's epithelium originally present, or do they appear only after some period of ...
		Barrett's mucosa is a metaplastic columnar epithelium that replaces the normal squamous epithelium in the esophagus.
		The glandular structures of the fundic type epithelium appear sparse and shortened causing it to appear atrophic compared to normal gastric mucosa [1-3].
		The specialized columnar epithelium in Barrett's mucosa has a special significance in this condition: when adenocarcinoma of the esophagus develops in Barrett's mucosa, it virtually always arises in a short or long segment of specialized metaplastic columnar epithelium and not from fundic or cardiac type epithelium [3].

	LLU - EPITHELIUM
		Transitional (urothelium) is a special type of stratified epithelium which lines the ureter and urinary bladder, and has large distinctive cells on its surface, which may have two nuclei.
		Some of its components are fibronectin; collagen IV and V. It is usually separated from the epithelium by an electron clear band (lamina rara) thought to be bridged by laminin.
		The smaller ones, surrounded by secretory units, are intralobular, while the larger ones are found in connective tissue between lobules and are called interlobular and interlobar ducts.

		In a 2002 study Dr Lowell Parsons of UCSD administered the potassium sensitivity test to men with CPPS and found that 84% had positive reactions, a rate almost identical to that reported in patients with interstitial cystitis, suggesting that prostatitis and interstitial cystitis may be a continuum of lower urinary epithelial dysfunction.
		Dr Parsons suggests reclassifying the prostatitis-interstitial cystitis disease process as lower urinary dysfunctional epithelium.
		Dr Parsons maintains that if caught early, good control of symptoms can be achieved with heparinoid therapy (eg.

		Except in the very most severe cases of dry eye where more of the corneal tissue may become compromised, the corneal epithelium is the part of the eye we dry eye patients care about most.
		It is disruption to the proper lubrication and adherence of tear film to the epithelium which causes dry eye symptoms.
		Sometimes anatomical defects in the epithelium itself (see ABMD) may also play a role.
