Immunotherapy using slow-cycling tumor cells prolonged overall survival of tumor-bearing mice

Table 1 Tumor-generation assay after using injection of 500, 1,000 or 5,000 DiI-positive cells^{a, b}.

	Tumor generation, n/total n			Mean time to tumor generation, days
cell injection	5,000^c	1,000^d	5,00^d	5000	1000	500
DiI^high cells	5/5	3/5	1/5	28	29	37
DiI^- cells	3/5	1/5	0/5	21	24	--

^aExperiments were repeated three times with similar results; this table presents the result of one experiment.
^b DiI^high cells were isolated using DiI-based fluorescence-activated cell sorting.
^{c, d}The t-test was carried out to determine the difference between the two groups in three experiments: ^c P < 0.01; ^d P < 0.05,).
