Abstract
The present invention provides a novel method for the establishment of tumorigenic cell lines from biopsies of human or animal tumors. The method includes preparing a single-cell suspension of a tumor cells by injecting cell culture medium into an isolated tumor or a portion thereof to flush out the tumor cells. The tumor or portion thereof may be in a cell culture maintenance medium. The step of injecting cell culture medium into the isolated tumor or portion thereof involves piercing the tumor or portion thereof with a needle to inject the cell culture medium and flush out the tumor cells. The steps of piercing the tumor or portion thereof with a needle and injecting the cell culture medium to flush out the tumor cells preferably are repeated until the single-cell suspension has a particular cell density. The method also includes establishing a primary tumor cell culture by growing the cells from the single-cell suspension in a cell culture medium.
