Tumorigenic Yes
Effects
Yes, solid tumors developed within 6 weeks in nude mice inoculated with 2 x 106 cells subcutaneously
Comments
CAL 27 cells are epithelial, polygonal with a highly granular cytoplasm.
Immunocytochemical studies show strong positive staining with anti keratin antibodies.
The cells do not grow well in semi-solid medium.
Marked inhibition of thymidine incorporation was observed in the presence of VP16 (etoposide), CCNU (1-[2-chloroethyl]-3-cyclohexyl-1-nitrosourea), VM26 (teniposide), ADM (adriamycin), CPA (cyclophosphamide), and MTX (methotrexate).
CAL 27 cells were resistant to treatment with VDS (vindesine sulfate), CDP (cis-platinum) or ACTD (actinomycin D).
A culture submitted to the ATCC in December 1993 was found to be contaminated with mycoplasma. Progeny were cured by a 21-day treatment with BM Cycline.
Complete Growth Medium The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing
Remove spent medium, add fresh 0.25% trypsin, 0.53 mM EDTA solution, rinse and remove trypsin. Add fresh trypsin and let the culture sit at room temperature (or at 37°C) until the cells detach. Add fresh medium, aspirate and dispense into new flasks.
Subcultivation Ratio: A subcultivation ratio of 1:6 is recommended
Medium Renewal: Every 2 to 3 days
Cryopreservation
Freeze Medium: Complete growth medium, 95%; DMSO, 5%
Storage Temperature: Liquid nitrogen vapor temperature
Culture Conditions
Temperature: 37°C
