Lack of correlation between rapid platelet- and neutrophil-producing activity in individually analyzed mPB samples. Low numbers of Lin⁻ALDH⁺ cells from 3 different mPB preparations were transplanted into NSG mice and the levels of human platelets and neutrophils present 3 weeks later in the PB and BM, respectively, were determined. Each data point indicates an individual mouse and mice positive for only one of the 2 lineages or both are shown separately.
