lin^neg SSC^lo ALDH^br CD34⁺, lin^neg SSC^lo ALDH^neg CD34⁺, and lin^neg SSC^lo ALDH^br CD34^neg cells were isolated (Figure 1) and cultured in short-term myeloid clonogenic assays, as described in “Materials and methods” (n = 7). The total numbers of myeloid colonies was normalized per 100 cells that initiated each culture. Statistical comparisons (P) were drawn between the lin^neg SSC^lo ALDH^br CD34⁺ and the lin^neg SSC^lo ALDH^neg CD34⁺ cell fractions using paired, 1-tailed nonparametric analyses (Wilcoxon signed rank test).
