Properties
Karyotype |
modal number = 61; range = 55 to 64. This is a hypotriploid human cell line. The modal chromosome number is 61, occurring in 28% of cells. The rate of higher ploidies is 1.2%. Twelve marker chromosomes are common in these cells. These include t(7q,16q), t(5p,7p), t(4q,9q) and 9 others. A large number of DM''''''''s is found in every cell. The N21 is absent; and N9, N11, N13, N20, N22 and X are single-copied. No Y chromosome was detected in the Q-banded slide preparation. |

Derivation |
This line was derived from cells present in ascites fluid obtained from a patient after treatment with 5-fluorouracil.
|
Clinical Data |
33 years
Caucasian
male
|
Tumorigenic | Yes |
Effects |
Yes, in nude mice
(Tumors developed within 21 days at 100% frequency (5/5) in nude mice inoculated subcutaneously with 10(7) cells)
|
Comments |
The cells contain Dopa decarboxylase and, unlike other colorectal lines, contain cytoplasmic dense core granules characteristic of endocrine secretion. The cells do not express the TAG-72 or CA19-9 antigens nor do they produce carcinoembryonic antigen (CEA). |
Background
Complete Growth Medium |
The base medium for this cell line is ATCC-formulated RPMI-1640 Medium, ATCC 30-2001. To make the complete growth medium, add the following components to the base medium: fetal bovine serum (ATCC 30-2020) to a final concentration of 10%. |
---|---|
