Heterogeneity in cycling activity of CD62L+/− fractions is unique to the MPP4 population. (A) Average percentage in BM LSK of each population (n = 8). (B) qRT-PCR analyses for gene expression in CD62L+/− MPP4 cells isolated of 8-wk-old control mice. Results are expressed as fold change ± SD relative to CD62L+ MPP4 cells, set at 1. n = 3; Student’s t test; *, P ≤ 0.05; ***, P ≤ 0.0005; ****, P ≤ 0.0001. (C) Representative FACS plots showing RFP fluorescence in hematopoietic populations of 8-wk-old control and Ki67-RFP mice. Fluorescence in wild-type mice was overlaid as fluorescence minus one (FMO). Mean percentage ± SD of RFP− cells indicated on each plot (n = 3). (D) Representative FACS plots and relative percentages of CD62L expression in early BM hematopoietic populations (HSC, MPP5, MPP2, MPP3, MPP4) and lineage-committed progenitors (GMP, CLP) in 8-wk-old mouse (n = 4). (E and F) Percentage ± SD of RFP− cells in total, CD62L+/− MPP3, and MP (Lin−cKit+ Sca1−) populations (E). Representative FACS plots showing RFP fluorescence in CD62L+/− MPP3 and MP populations (F) (n = 3). (G) Mean percentages ± SD of Edu incorporation in total, CD62L+/− MPP3, and MP populations (n = 8). All data are from two independent experiments.
