Cell Line Origin
Human oral squamous cell carcinoma, buccal mucosa
Cell Line Description
Established from a squamous cell carcinoma (SCC) of the buccal mucosa (20mm-40mm) of a 53 year-old female patient. STNMP stage II, moderately differentiated, node negative tumour. Mutant p53, codon 68 exon 4, G to T; wild type K-, N- and Ha-ras. These cells are non-tumourigenic on subcutaneous injection into athymic nude mice, but tumourigenic on injection into the floor of the mouth.
DMEM:HAMS F12 (1:1) + 2mM Glutamine + 10% Foetal Bovine Serum (FBS) + 0.5 ug/ml sodium hydrocortisone succinate
Split sub-confluent cultures (70-80%), approximately every 5-6 days, 1:8 to 1:10 using 0.25% trypsin/EDTA; 5% CO2; 37°C. Suggested seeding density 5 x 1000 cells/cm2. Cells can take approximately 10 minutes to detach, an alternative is to trypsinise 2 to 3 times with fresh trypsin for shorter periods for each trypsin application. Avoid knocking flasks during the trypsinisation process as this can lead to loss of viability.
