The cells consistently have 18 to 20 marker chromosomes. They are: (t(1;?), del(1)(p13), del(2) (p11), t(2;?), t(7p, 19p), t(8;?), t(11;11) (p15;q13), t(14q,21q), t(6p,16p), t(X;?), and 10-12 others. There is only one copy per cell of structurally unchanged normal chromosomes for Nos. 1,2, 4, 10, 14, 16, and 18. No. 20 generally has 4 copies per cell and the X has 3 copies per cell.

Age: 65 years
Gender: female
Ethnicity: Caucasian
Comments:The epithelial cell line, LS123, was established by L.P. Rutzky et al, in 1974 from the second in a series of three primary colonic tumors resected from a 65 year old Caucasian female.
In 1950, a primary colon tumor was resected from the patient (41 years old at that time).
24 years later a second primary tumor classified as a Dukes' type B mucin producing colon adenocarcinoma was excised and the cells were cultured.
A third primary tumor was discovered in 1980 in an area just proximal to the colostomy and was resected.
The established cell line is aneuploid, releases small amounts of carcinoembryonic antigen, fails to grow progressively in nude mice, and forms colonies only in enriched semisolid medium developed for tumor stem cells.
LS123 cells grow as confluent cell monolayers in either low serum or serum free medium.
In the chick embryonic skin assay, the cells grow as a well differentiated abnormal colonic epithelium with little mitotic activity and low invasiveness.
Although LS123 exhibits several properties associated with neoplasia, they have little invasive potential and may represent an early stage in tumor development.
The plating efficiency is 12% in the medium recommended below.
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 10%.
Temperature: 37.0°C
Subculturing: Protocol:
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended
Medium Renewal: Every 2 to 3 days
Preservation: Freeze medium: Complete growth medium, 95%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
Related Products:Recommended medium (without the additional supplements or serum described under ATCC Medium):ATCC 30-2003
recommended serum:ATCC 30-2020

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 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.
