Establishment and Characterization of Oral Cancer Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
ORL-48, ORL-204 and ORL-188 oral cancer cell lines isolated respectively from gingiva (gum), buccal mucosa (lining of the cheeks and back of the lips) and tongue were obtained from Cancer Research Malaysia (Subang Jaya, Selangor). These cells were established from surgically resected specimens obtained from untreated primary human oral squamous cell carcinomata of the oral cavity as in vitro models to study a disease prevalent in Asia. Their growth characteristics, epithelial origin and molecular alterations were previously characterized (24 (link), 25 (link)). Genetic information and clinical data associated with these ORL cell lines are available at https://genipac.cancerresearch.my/ (26 (link)). ORL-48, ORL-204 and ORL-188 cells were cultured and maintained in DMEM/F-12 medium (Nacalai Tesque Inc., Kyoto, Japan) supplemented with 10% foetal bovine serum (Nacalai Tesque Inc.) and 0.1% penicillin-streptomycin (Sigma-Aldrich, Merck) at 37 °C and 5% CO2.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
