TREC values after transplantation. All data points in surviving patients are shown. TRECs are expressed in number per 100 000 cells. Normal values in infants are approximately 10 000/100 000 cells.³⁰  CD3 TRECs are reported except as stated here to indicate CD4 and CD8 TRECS were assayed separately.³  The early time points for DIG001 and DIG005 are CD4 TRECs except the last data point for each. The CD4 TREC data for patients DIG001 and DIG005 have previously been reported.²³  For DIG006 and DIG007, all are, except the last 3 and 2 data points, respectively, CD4 TRECs.
