Number of tetramer⁺ cells from representative melanoma patient

	Experiment 1	Experiment 2	Experiment 3
Control	1.45/1	1.68/1	0.45/1
IL-21	17.14/11.82	23.17/13.79	8.37/18.60
CD 25 depletion	8.20/5.66	12.64/7.52	4.35/9.67
CD25 depletion + IL-21	244.94/168.92	462.65/275.38	141.00/313.33

The absolute number in millions of tetramer⁺ cells corresponding to each experimental culture from a representative melanoma patient, depicted in Figure 1, and the fold increase in absolute numbers of CD25 depletion and/or IL-21 treated to untreated cultures (control). Representative results from 3 separate experiments are presented.
