Description | Tissue repair and wound healing in the cornea is accomplished mainly by the corneal fibroblasts, and these cells are responsible for pathological process in the degenerative corneal disorders such as keratoconus. Established using the HPV16 E6/E7 genes, The Immortalized Human Corneal Fibroblasts (IHCF) not only retains its authentic cell biomarkers (CD36, ECM protein collagen I and S100A4), it also displays fairly disomic cytogenetic status at chromosomes 1, 8, 10 and 18, which is an indication of normal diploid chromosomal status. Together with the Immortalized Human Corneal Keratinocytes (T0579) and the Immortalized Human Corneal Endothelial cells (T0577) isolated from the same donor and immortalized using the same platform, this uniform model system presents a valuable tool for studies involving cornea homeostasis and ophthalmologic diseases. |

Propagation | Use of PriCoat? T25 Flasks (G299) or Applied Cell Extracellular Matrix (G422) is required for cell adhesion to the culture vessels. Grow cells in ECM-coated culture vessels with the following conditions. The base medium for this cell line is PriGrow III (TM003). To make the complete growth medium, add the following components to the base medium: 10% fetal bovine serum (TM999) and Penicillin/streptomycin. Atmosphere: air: 95%, CO2: 5%; Temperature: 37.0°C. |
Preservation | 1. Freeze Medium: Complete growth medium with 20% FBS and 10% DMSO. 2. Storage Temperature: Liquid nitrogen vapour phase. |
Quality Control | 1) RT-PCR was used to evaluate the transgene expression of HPV16 E6/E7; 2) Indirect immunofluorescence was performed to detect the cell specific marker expression CD36, ECM protein collagen I, and S100A4; 3) FISH was used to examine the cytogenetic alterations in the immortalized cells. |
Disclaimer | 1. The CoA for this product (provided upon request) verifies the cell-type specific gene expression via RT-PCR only. All test parameters provided in the CoA are conducted using abm's standardized culture system and procedures. The stated values may vary under the end-user's culture conditions. Please verify that the product is suitable for your studies by referencing published papers or ordering RNA (0.5 μg, Cat.# C207, $450.00) or cell lysate (100 μg, Cat.# C206, $600.00) to perform preliminary experiments, or alternatively use our Gene Expression Assay Service (Cat# C138). All sales are final. 2. We strongly recommend live cell shipments for ease of cell transfer and this option can be requested at the time of ordering. Please note that the end-user will need to evaluate the feasibility of live cell shipment by taking into account the final destination's temperature variation and its geographical location. In addition, we thoroughly test our cell lines for freeze-thaw recovery. If frozen cells were received and not recovered in your lab under the exact, specified conditions (using recommended culture vessel, media, additional supplements, and atmospheric conditions), a live cell replacement is possible at a cost (plus shipping). 3.
