Different stages of B lymphoid maturation were identified in normal bone
marrow using multiple cell surface markers. The proliferation status of
each of these maturational stages was determined by simultaneous
quantitative DNA analysis on a flow cytometer. The technique used to
quantify these parameters preserved the cell surface immunofluorescence,
the light scattering properties and the stoichiometric binding to DNA. The
proliferating cells were confined to a distinct population of cells
expressing CD10. The number of proliferating cells in these populations was
relatively constant among 12 separate bone marrow samples. The data suggest
that the timing and rate of proliferation of cells within a single lineage
may be a preprogrammed aspect of normal maturation.
