CD2 and acute myeloid leukemia: To assess whether this effect was mediated by different T cell doses that were co-transplanted with MNCs from AML patients (7.5±8.4×105, n = 14) or healthy donors (27.4±23.5×105, n = 9), we transplanted titrated numbers of sorter-purified human CD2+ T cells into NSG recipient mice and analyzed human T lymphocyte frequencies in the blood (Figure 3F) and bone marrow (Figure 3G) of the recipient mice.
