  • Patent number: 8765464
    Abstract: The present invention provide: a novel process for culturing animal cells and a kit for culturing animal cells, in which, even if the number of cells as sampled for biopsy is extremely small, the proliferation can sufficiently be maintained so as to enable to carry out various culture and/or tests, especially anticancer agent sensitivity tests, and the contamination with bacteria can be inhibited without damaging physiological activity of cells, especially sensitivity to anticancer agents. The process for culturing animal cells, according to the present invention, comprises the step of culturing a sample containing animal cells obtained from living body tissue in order to subject the sample to further culture and/or a test, with the process being characterized in that a culture medium is used wherein the culture medium has a proliferating action and physiological activity-retaining action on the animal cells, and further has a killing action and/or multiplication-inhibition action on bacteria.
