Enrichment for CFU-C from murine and human bone marrow using soybean agglutinin. 1982

Y Reisner, and N Kapoor, and M Z Hodes, and R J O'Reilly, and R A Good

Mouse bone marrow and spleen cells agglutinated by soybean agglutinin (SBA) or peanut agglutinin (PNA) were previously shown to be enriched for spleen colony-forming cells (CFU-S) and sufficiently depleted of graft-versus-host reaction producing cells to allow hematologic reconstitution of lethally irradiated allogeneic recipient mice. A similar enrichment for cells capable of forming colonies in soft agar culture (CFU-C) has now been found in the SBA-agglutinated fraction of mouse bone marrow cells, in contrast to the finding that in human bone marrow the majority of the CFU-C are in the fraction not agglutinated by SBA. Cytofluorometric studies with fluorescein-labeled SBA (FITC-SBA) revealed that the majority of both mouse and human bone marrow cells bind the lectin. Experiments mixing the human marrow fractions separated by SBA reveal that true enrichment for CFU-C is achieved in the unagglutinated fraction, as opposed to a possible depletion of a suppressor cell population. Granulocytic, monocytic, and mixed cell colonies were all enriched in the SBA-unagglutinated cell fraction from human bone marrow.

D005434	Flow Cytometry	Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
