Establishment of human colon carcinoma lines in nude mice

Exp Cell Biol. 1979;47(2):136-44. doi: 10.1159/000162930.


After subcutaneous inoculation into nude mice of 24 human colon adenocarcinomas, growth, defined as histopathologically confirmed tumor growth which has been passed, was observed in 13 cases (54%). Tumors from metastatic sites showed higher take rates (58%) than tumors from primary sites or recurrent tumors (50%). Nine continuous tumor lines were established (69% of growing tumors) with metastatic tumors establishing more readily (100% of growing tumors) than primary tumors (40%). The average period in primary transplant was shorter for metastasis (8.3 weeks), than for primary tumors (18.5 weeks); total material 10.6 weeks. Average periods between passages were shorter than primary transplant times; these periods were shorter for metastases (6.6 weeks) than for primary tumors (9.4 weeks); total material 7.4 weeks. Of four growing tumors not established as continuous lines, three were primary and one a recurrent tumor, and the loss of tumor growth occurred in very early passages, not later than passage 3. All nude mouse-grown colon tumors were moderately well differentiated.
