Tumorigenic: Yes

Antigen Expression: Blood type A; Rh+

Cytogenetic Analysis: SNU-C2A細胞modal number = 46; range = 44 to 48.

This is a pseudodiploid human cell line. The modal chromosome number is 46, occurring at 86%, with polyploidy at 16.2%. The ins(1;?)(p13;?), del(3)(p23), t(4q,?), t(8;?), del(9)(p13), del(11)(p13), 14q+ and two other marker chromosomes are common to all metaphases examined. Other altered chromosomes, if any, occur only sporadically. Normal N11 is absent. Two copies of X chromosomes are found in each cell. The Y chromosome is not found in QM stained preparations.

Comments: This is one of 14 colorectal carcinoma cell lines derived by J.G. Park and associates during the years 1982 through 1985.

The line was obtained from a third passage nude mouse xenograft of tumor fragments obtained from a patient prior to therapy.

SNU-C2A細胞The line was initially grown in RPMI 1640 medium with 20% fetal bovine serum, but was later adapted to growth in the chemically defined medium ACL-4 (it can also be grown in medium with 10% serum).

The cells and tumors formed from the cells produce detectable amounts of Dopa decarboxylase and the TAG-72 antigen.

Propagation: ATCC complete growth medium: ACL-4 medium supplemented with 10% FBS

The base medium for this cell line is ATCC-formulated DMEM: F12 Medium Catalog No. 30-2006. To make the complete growth medium, add the following components to the base medium:

0.02 mg/ml insulin

0.01 mg/ml transferrin

25 nM sodium selenite

50 nM Hydrocortisone

1 ng/ml Epidermal Growth Factor (do not filter)

0.01 mM ethanolamine

0.01 mM phosphorylethanolamine

100 pM triiodothyronine

0.5% (w/v) bovine serum albumin

10 mM HEPES

0.5 mM sodium pyruvate

2mM L-glutamine(for final conc. of 4.5 mM)

10% FBS
