Karyotype	modal number = 69; range = 51 to 72. This is a hypertriploid human cell line with the modal chromosome number of 71, occurring in 24% of cells. Most cells had the chromosome numbers distributed between 69 and 72. Polyploid cells occurred at 7.6%. Fifteen or more marker chromosomes were common to most cells. Among them are dup(2) (q22q31) and del(2) (q31) which probably resulted from the balanced translocation between two N2s. Most cells had two copies of del(2). M2 is an A3-sized acrocentric. M13 is a minute submetacentric with 1-3 copies per cell. Origins of both M2 and M13 are not identified. There were two copies of normal X chromosomes. N2 was absent and probably was replaced by dup(2) and del(2).
Derivation	This line was established from fragments of a primary tissue sample obtained after surgery from a Japanese patient.
Clinical Data	55 years adult Asian female This line was established from fragments of a primary tissue sample obtained after surgery from a Japanese patient.
Oncogene	p53 +; pRB +
Genes Expressed	Oncogenes: p53 +; pRB +
Tumorigenic	Yes
Effects	Yes, in nude mice; forms poorly differentiated epidermoid carcinoma (grade III)
Comments	Electron microscopic observations revealed presence of typical desmosomes at the cell junctions and an abundance of tonofilaments in the cytoplasm. Mycoplasma contamination was detected and eliminated in 1975. The line is reported to contain an integrated human papillomavirus type 16 genome (HPV-16, 1 to 2 copies per cell).

Complete Growth Medium	The base medium for this cell line is ATCC-formulated Eagle''s Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing	Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes. Remove and discard culture medium. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor. Add 2.0 to 3.0 ml of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes). Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting. Add appropriate aliquots of the cell suspension to new culture vessels. Incubate cultures at 37°C. Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:8 is recommended Medium Renewal: 2 to 3 times per week
Cryopreservation	Freeze medium: Complete growth medium supplemented with 5% (v/v) DMSO Storage temperature: liquid nitrogen vapor phase
Culture Conditions	Atmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 37°C
