Graph showing Tumor weight versus days since Subcutaneous implant of the HL-60 tumor in SCID mice. There were five groups in the study. Group 1: 1x10^7 cells were implanted SC. 100% Take Rate Group 2: 5x10^6 cells were implanted SC. 100% Take Rate Group 3: 1x10^6 cells were implanted SC. 10% Take Rate Group 4: 5x10^5 cells were implanted SC. 10% Take Rate Group 5: 1x10^5 cells were implanted SC. 0% Take Rate Notes: Ten animals were assigned to each group. Starting at Day 22, animals in various groups that had reached endpoint were removed from the study resulting in fluctuations in the growth curves at subsequent time points. Growth curves were no longer calculated when <70% remained in the group.
