  • The supravital, mitochondrial specific dye Rhodamine 123 (R123) was used in conjunction with three monoclonal antibodies to isolate a population of human bone marrow (BM) cells enriched for hematopoietic progenitor cells. BM cells stained with phycoerythrin-HLA-DR, Texas red-CD34, allophycocyanin-CD15, and R123 were fractionated using four-color immunofluorescence cell sorting. Cells expressing CD34 but not HLA-DR and CD15 (CD34+ HLA-DR- CD15-) were subdivided according to their reactivity with R123 into quiescent, R123 dull (R+) or cycling, R123 bright (R++) subpopulations. Morphological analysis and hematopoietic progenitor cell assays indicated that CD34+ HLA-DR- CD15- R+ cells contained larger numbers of blast cells and colony forming units than CD34+ HLA-DR- CD15- R++ cells. The flow cytometer settings used to accommodate the detection of the R123 fluorescence in combination with that of three other fluorochromes are described.
