| Cytogenetic Analysis: | This is a near diploid line. The modal chromosome number is 47 occurring at 38%, and the rate of polyploidy is 9%. Fifteen to sixteen marker chromosomes are present in all cells. They are t(1,?), t(3p,5q), der(3)t(?q29;?), t(3q,?), 5q+, i(6p), t(7q,?), 9q+, t(10q,21q), 16q+ and five to six others. Normal chromosomes 3, 10, 13 and 16 are absent. There are two copies of the X chromosome. No Y chromosomes were detected in QM stained preparations |

| Comments: | The WERI-Rb-1 line is one of two human retinoblastoma cell lines established in 1974 by R.M. McFall and T.W. Sery. The cells survive culturing in Difco Bacto-Agar but do not form colonies. Scanning electron microscopy reveals some variation in the number and frequency of surface blebs, lamellipodia and microvilli. The line is of interest in studies of cell differentiation, animal models of tumor therapy and biochemical evaluations. |

| Propagation: | ATCC complete growth medium: The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, Catalog No. 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Atmosphere: 5% CO2 in air recommended
Temperature: 37.0°C |
|
|
| Subculturing: | Protocol: Cultures can be maintained by addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension in fresh medium at 2 - 3 X 10 exp5 viable cells/ml. Maintain cell density between 1 X 10 exp5 and 1 to 2 X 10 exp6 viable cells/ml.
Medium Renewal: Every 3 to 4 days |
|
|
| Preservation: | Freeze medium: Complete growth medium, 95%; DMSO, 5%
