a, Schematic representation of systemic NALM6 tumour model. b, Tumour burden (total flux in photons per second) of NALM6-bearing untreated mice (n = 4), or mice treated with 4×106 CD8 TRAC-1XX (n = 5) or TRAC-1XX-iT cells (n = 7, line = one mouse). c, Kaplan-Meier analysis of tumour-free survival (left) and overall survival (right). d, Flow cytometric quantification of tumour cells (left) and T cells (right) in bone marrow 12 days after T cell infusion (n = 2–3 mice). e, Phenotype of persisting TRAC-1XX-iT cells prior to infusion (day 0, n = 1) and of cells derived from the bone marrow on day 6 and 12 days after TRAC-1XX-iT cell infusion (n = 3 mice). * P<0.05, ** P<0.01, *** P<0.001, log-rank Mantel-Cox test (c), Welch’s 2-sample two-sided t test (d). All data are means ± s.d.
