Abstract
This paper describes the kinetics of fibroblastic colony forming units (CFU-f) in murine blood after phenylhydrazine-induced haemolytic anaemia and their subsequent migration into haemopoietic organs. Murine blood contained 5.3 +/- 0.8 CFU-f per 10(6) nucleated cells. Absence of particle ingestion and factor VIII-related antigen in addition to the enzyme pattern in CFU-f-derived cells confirmed that these cells did not have a macrophage-like or endothelial nature. Phenylhydrazine treatment of mice resulted in a 3-fold increase in blood CFU-f numbers which was accompanied by increases in blood cellularity and granulocyte-macrophage progenitor numbers. When both partners of CBA/N and CBA/T6T6 mice in parabiosis had been treated with phenylhydrazine, spleens and femoral bone marrow of both mice were shown to contain partner-derived CFU-f. These data suggest that circulating CFU-f represent a stromal cell population which can migrate into haemopoietic organs.
