Hierarchical distribution and cell cycle status of hematopoietic stem and progenitor cells.
(A) Schematic illustration of hematopoietic development. The expression levels of cell surface markers (such as Sca-1, c-Kit, and IL-7R) revealed by microarray analysis are indicated. CD34 and FcγRII/III are not included in the chips. γ represents Pearson correlation coefficient, which reflects the developmental distance between 2 populations of cells. (B) Analysis of cell cycle status of hematopoietic stem and progenitor cells. HSCs (Rhlo KLTS) and MPPs (Rhhi KLTS) were stained with Hoechst 33342, and the cell cycle statuses were represented by DNA contents.
