Abstract

The effect of stem cell factor (SCF) on the establishment of hematopoietic activity in murine long-term bone marrow cultures (LTBMC) was investigated by addition of SCF to (a) normal LTBMC from the onset of culture and (b) pre-established irradiated bone marrow stroma inoculated with lineage negative (Lin-) primitive hematopoietic progenitor cells enriched on the basis of low rhodamine-123 uptake (Rh-dull). Hematopoietic activity was established more rapidly in LTBMC grown in the presence of SCF (70 ng/mL), and the typical decline in cellularity and progenitor cell content during the first weeks of culture was not observed. SCF also promoted the rapid expansion of progenitor cells derived fr..
