Peripheral blood cell counts. (A) Total WBCs, (B) RBCs, and (C) platelets were counted in FL-overexpressing (□) and control (▪) animals as a function of time posttransplantation, as described. Results are from a representative experiment. The number of animals analyzed (n) in this experiment is as follows: n = 10 for each group from 0 to 5 weeks posttransplantation, n = 5 in the control group for weeks 6 through 13 posttransplantation, n = 5 in the FL-overexpressing group from week 6 through 9 posttransplantation, n = 3 in the FL-overexpressing group from week 10 through 11 posttransplantation, and n = 2 in the FL-overexpressing group from week 12 through 13 posttransplantation. The data are expressed as an arithmetic mean of cell counts (±1 SEM). The significance of difference between FL-expressing and control animals at each time point was determined using the Student's t-test and is indicated: *P < .001; **.005 < P < .001.
