CD38 and Sepsis: We evaluated the distribution and frequency of immunophenotypic common myeloid progenitors (CMPs; CD34+CD38+CD135+CD45RA−), granulocyte–macrophage progenitors (GMPs; CD34+CD38+CD135+CD45RA+),megakaryocyte–erythroid progenitors (MEPs; CD34+CD38+CD135−CD45RA−), hematopoietic stem cells (HSCs; CD34+CD38−CD90+CD45RA−), and multipotential progenitors (MPPs; CD34+CD38−CD90−CD45RA−) in sepsis patients and healthy controls (van Galen et al., 2014; Notta et al., 2016).
