Rat Primary Colonic Epithelial Cells from Gentaur are isolated from tissue of 1-day-old neonatal laboratory Sprague–Dawley Rats. Rat Primary Colonic Epithelial Cells are grown in T25 tissue culture flask pre-coated with gelatin-based coating solution for 0.5 hour and incubated in Gentaur's Cell Culture Medium for 3-5 days. Cells are detached from flasks and immediately cryo-preserved in vials. Each vial contains 1x10^6 cells and is delivered frozen.Rat Primary Colonic Epithelial Cells are characterized by immunofluorescent staining with antibodies of E-cadherin or ZO-1. Rat Primary Colonic Epithelial Cells are negative for bacteria, yeast, fungi, and mycoplasma. Cells can be expanded for 3-7 passages at a split ratio of 1:2 under the cell culture conditions specified by Gentaur. Repeated freezing and thawing of cells is not recommended.Standard biochemical procedures performed with epithelial cell cultures include the assays of cell to cell adhesion and migration, RT-PCR, Western blotting, immunoprecipitation, immunofluorescent staining or immunofluorescent flow cytometry or generating cell derivatives for desired research applications.

The colorectum is a major organ for both malignant and nonmalignant diseases. Cells that line the colonic mucosal surface form a major mechanical barrier that separates the host’s internal milieu from the external environment. In addition to the well-established role of epithelial cells in ion transport, these cells appear to function as an integral component of the mucosal immune system. Human colon epithelial cells can process and present antigens to T cells in vitro, and can be stimulated to express HLA class II and intercellular adhesion molecules in vivo. They also respond to a broad array of cytokines with altered gene expression and growth characteristics. In addition, normal colonic epithelial cells were found to express the integrin α3, α5, α6, β1 and β4 chains. HCoEpiC from Gentaur Research Laboratories are isolated from human colonic tissue. HCoEpiC are cryopreserved at passage one and delivered frozen. Each vial contains 5×10^5 cells in 1 ml volume. HCoEpiC are characterized by immunofluorescent method with antibodies to CK18 and CK19. HCoEpiC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HCoEpiC are guaranteed to further culture for 15 population doublings in the conditions provided by Gentaur Research Laboratories.

The conjunctival epithelium is a stratified, non-keratinized epithelium. It can be distinguished by the corneal epithelium by the expression of different cytokeratins, mucins and by the presence of glycocalix. Decrease or loss of mucin/glycocalix production generates squamous metaplasia, which may lead to dry eye and ocular surface diseases. Human conjunctival epithelial cells represent potential target cells for mast cell mediators. They respond to histamine by generating inositol phosphates, mobilizing intracellular calcium, and then secreting proinflammatory cytokines like interleukin-6 and interleukin-8.HConEC from Gentaur Research Laboratories are isolated from human conjunctiva. HConEC are cryopreserved from passage one culture. Each vial contains 5×10^5 cells in 1 ml volume. HConEC are characterized by their cobble stone morphology in serum-free culture and immunofluorescent method with antibody to CK-18 and -19. HConEC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HConEC are guaranteed to further expand for 10 population doublings at the condition provided by Gentaur Research Laboratories.

The cornea is a unique tissue for two reasons: the transparency function and the synthesis of most of its proteins due to the cornea being an avascular tissue. The cornea consists of three distinct cell layers, the outer epithelium, the inner endothelium and the central stroma (the keratocytes). The corneal epithelium plays a role in the innate immune response by sensing the presence of pathogens and providing signals that activate the corneal defense system. It also highly expresses aldehyde dehydrogenase to protect against UV- and 4-hydroxynonenal-induced cellular damage. Corneal epithelial basal cell proliferation is controlled by a host of cytokines, e.g., epidermal growth factor, that activate their cognate receptors in the deeper layers of the epithelium. Instead of testing products in the eyes of animals, cultured corneal epithelial cells could be used for toxicology tests in in vitro models and for studying the molecular mechanisms involved in regulating human corneal epithelial cell differentiation.HCEpiC from Gentaur Research Laboratories are isolated from human cornea. HCEpiC are cryopreserved from passage one culture. Each vial contains 5×10^5 cells in 1 ml volume. HCEpiC are characterized by their cobble stone morphology in serum-free culture and immunofluorescent method with antibody to CK-18 and -19. HCEpiC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HCEpiC are guaranteed to further expand for 10 population doublings at the condition provided by Gentaur Research Laboratories.

The human esophagus is lined by a non-keratinizing, moist stratified squamous epithelium whose apical cell membranes and intercellular junctional complexes combine to produce an effective permeability barrier against the influx of luminal content. In particular, the barrier created by these structures limits exposure of the surface cells' basolateral cell membranes and entire membrane of cells of the deeper layers to the wide swings in osmolality occurring regularly within the esophageal lumen. Histologically, the esophageal epithelium consists of two zones, the basal and differentiated zones. Cellular proliferation is limited to the basal zone, and cells are thought to migrate from this area towards the esophageal lumen. Migration is associated with the initiation of differentiation and the sequential expression of differentiation markers. The availability of human esophageal epithelial cell culture provides an excellent in vitro model in the study of the physiology of esophageal epithelium and the mechanisms of the esophageal carcinogenesis.HEEC from Gentaur Research Laboratories are isolated from the human esophagus. HEEC are cryopreserved on passage one culture and delivered frozen. Each vial contains 5×10^5 cells in 1 ml volume. HEEC are characterized by immunofluorescent method with antibodies to cytokeratine-8, -18 and -19. HEEC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HEEC are guaranteed to further expand for 15 population doublings in the condition provided by Gentaur Research Laboratories.
