Flow cytometric analysis of CD34 and c-Kit expression on bone marrow cells from normal subjects and the patients with SCN. Nonadherent LDBMC enriched for CD34-FITC (see Materials and Methods) were stained by Kit-PE. R indicates the gate for CD34⁺/Kit⁺ cells. The figure shows a representative flow cytometric analysis for 2 patients with SCN and 2 normal subjects.
