Figure 5. Pf4 gene expression is identified in Stem and primitive progenitor cell populations.

Pf4 expression in LSK CD150+CD48− HSCs, LSK CD150−CD48−, LSK CD150+CD48+, and LSK CD150−CD48+ cells sorted from bone marrow of control mice. Relative Pf4 expression levels were calculated with the LT-HSC fraction set to the value of 1 (see methods). Results are mean±SD from three independent experiments.
