Concentration gradient of blood stem cells in mouse bone marrow--an open
question
MA Maloney, RA Lamela, MJ Dorie and HM Patt
The distribution of pluripotential blood stem cells (CFU-S) in bone marrow
was studied in four strains of mice. Analyses of paired samples containing
various fractions of axial and marginal bone marrow cells, as well as
longitudinal 200-micrometer sections, revealed a rather uniform spatial
distribution of CFU-S across the diameter of the femoral medullary cavity,
in contrast to the finding by others of a CFU- S concentration gradient
extending from the endosteum to the central longitudinal axis of bone
marrow. The existence of a stem cell gradient is therefore open to
question.
