Karyotype
|
aneuploid; modal number = 43
|
Derivation
|
Cal 27 was established in 1982 by J. Gioanni (Centre Antoine Lacassagne, Nice Cedex, France) from tissue taken prior to treatment from a 56 year old Caucasian male with a lesion of the middle of the tongue.
|
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.
