Comparative Mature Cell Accumulation and Kinetics by Transplanted Hematopoietic Stem and Progenitor Cell Populations
The total numbers of RBCs (A), platelets (B), GMs (C), B cells (D), and T cells (E) present per mouse per transplanted HSPC. (A′–E′) The approximate time points and cell numbers for peak donor-derived mature cells from (A–E), respectively.
Data were generated from the transplantation and cell distribution experiments of Figure 1. The mature cell production capacity was always in the same order: HSCs > MPPF > CLPF (for B and T cells) and HSCs > MPPF > CMP > CMPF > MEP > GMP (for RBCs, platelets, and GMs). The only exception was that significantly more GMs accumulated after CMPF than after CMP transplantation (C and C′; p < 0.0009 by Student's two-tailed t test). All other comparisons were also significant. See also Figure S3.
