TRECs and patient age at time of transplantation.
Circulating TRECs per 106 PBMCs were measured and plotted (y-axis) for patients who were younger than 19 years (▪, solid line) versus patients who were 19 years or older (○, dashed line) at the time of transplantation, as a function of time from transplantation (x-axis). The difference between the 2 curves is significant atP = .02. Note that the lower limit of detection for TRECs was 100 TRECs/106 PBMCs in the assay used.
