To understand the mechanisms responsible for splenic megakaryopoiesis in sepsis, we measured hematopoietic progenitor cells (megakaryocyte-erythrocyte progenitors [MEPs] and their precursors, Lin–c-Kit+Sca-1+ [LSK] cells) in the BM and blood during sepsis (see the gating strategy in Supplemental Figure 3A). This evidence concerns the gene KIT and Sepsis.
