Effects of neuraminidase on the regulation of erythropoiesis.

abstract：:We describe two assays to detect the action of colony-inhibiting cells. In the first assay, we used a simple density separation technique to remove dense neutrophils (PMN) from suspensions of blood and of bone marrow cells prior to culture in semisolid agar. Conditions were arranged to ensure that control suspensions ...
