Cytogenetic Analysis: The stemline modal chromosome number is 96, occurring at 16% with polyploidy at 3.2%. Ten common markers were detected i.e., t（1q;?）, 10q-, t（11q17q） and 7 others. The t（1q17q） and M11 were found in a portion of cells. The ins（2）, 10q-, and t（15q;?） were generally paired, and t（11q;17q） and t（21q;?） were mostly three-copied. Normal N9 was absent, and N21 was lost in some cells. One to 4 small acrocentric chromosomes were detected. No Y chromosome with bright distal q-band was detected by Q-observation.

Propagation: ATCC 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 20%.

Atmosphere: air, 95%; carbon dioxide （CO2）, 5%

Temperature: 37.0°C

Subculturing: Protocol:

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 which 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 37C 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.The recommended inoculum is 1 X 10（4） viable cells/cm2. Subculture cells when they are about 80% confluent, at a cell concentration between 8 X 10（4） and 1 X 10（5） cell/cm2.

Incubate cultures at 37C.

Subc*tion Ratio: A subc*tion ratio of 1:4 to 1:6 is recommended

Medium Renewal: 1 to 2 times per week

Preservation: Freeze medium: Complete growth medium, 95%; DMSO, 5%

Storage temperature: liquid nitrogen vapor temperature

Doubling Time: about 62 hours
