Quantification of subcutaneous tumor forming cells. Comparison of subcutaneously injected cells in relation to the number of colonized cells quantified using AMS (A) from the harvested tumor. Percentage of initially injected 14C-labeled cells retained in final tumor (B). At least 4 replicates were analyzed for each quantity of cells injected with the exception of 1.00E + 03 cells due to 14C signal below the level of detection (++).
