Accelerated, but not conventional, LTI markedly increases the percentages of 7AAD^int/hiCRT^hi, 7AAD^int/hiHsp70^hi, and 7AAD^int/hiHsp90^hicells in A20 and BL3750 B-cell lymphomas. (A) Representative 2-color FACS patterns of the percentages of 7AAD^int/hiCRT^hi, 7AAD^int/hiHsp70^hi, and 7AAD^int/hiHsp90^hi cells on CD19⁺ gated BALB/c A20 lymphoma cells within the boxes from 3 groups of mice. (B) Percentages (mean ± standard error of the mean) of 7AAD^int/hiCRT^hi (top panel), 7AAD^int/hiHsp70^hi (middle panel), and 7AAD^int/hiHsp90^hi (bottom panel) cells in panel A. n = 5 mice per group. (C) Representative 2-color FACS patterns of the percentages of 7AAD^int/hiCRT^hi, 7AAD^int/hiHsp70^hi, and 7AAD^int/hiHsp90^hi cells on CD19⁺ gated BL3750 lymphoma cells contained in boxes from 4 groups of mice. (D) Percentages (mean ± standard error of the mean) of 7AAD^int/hiCRT^hi, 7AAD^int/hiHsp70^hi, and 7AAD^int/hiHsp90^hi cells in panel C. n = 4 mice per group. Only significant P values are shown. *P < .05, **P < .01, Mann-Whitney U test.
