Strain KE-24 of colonic cancer cells was established from human colonic cancer diagnosed histopathologically as poorly differentiated adenocarcinoma. Doubling time of the cancer cell line was 32.4 hrs, and the karyotype was 46, xy, t (1q:?), 6p-, 14q+. The cancer cells could be heterotransplanted in 66% of nude mice. The plating efficiency was 17% in a soft agar plate with an inoculum size of 1 x 10(3) cells/dish. The tumor cells produced and released CEA and CA19-9 in the spent medium and these cancer cells were stained with both anti-CEA and anti-CA19-9 antibodies by the immunohistological staining method. Strain KE-24 of the cancer cells could be cultured in the serum-free medium (Media-I) for more than 100 passages.
