CD4 and leukemia: Similarly, relatively little heterogeneity was seen in comparisons of healthy BM B cells to healthy BM HSCs (IQR: 4.5, median: 10.1, N = 3), non-leukemia CD4+ T cells from AML BM to healthy BM HSCs (IQR: 2.7, median: 9.5, N = 3), and non-leukemia CD4+ T cells from AML BM to healthy BM HSCs (IQR: 2.4, median: 7.3, N = 3).
