[Strains of human gastrointestinal and uterine tumors transplantable into athymic mice and rats].

The authors describe strains of human cancer of the stomach, colon, cervix and corpus uteri as well as uterine chorionepitheliomas transplanted into nude mice and rats. The histological appearance of these strains is in full accordance with that of primary tumors. Electrophoresis of lactate dehydrogenase isozymes indicates that the strains mainly consist of human cells. The strains are transplanted in nude animals at various time intervals. The strains of human gastric cancer are transplanted from animal to animal in a month and those of corpus uteri in a week.
