CFU-F (colony forming units-fibroblast) were studied from cord blood and, as controls, from normal bone marrow of older children and adults. Numbers of CFU-F in cord blood buffy coat cells are lower by a factor of 10 in comparison to bone marrow CFU-F. Cytomorphology and staining with monoclonal antibody identify the progeny cells of CFU-F as fibroblasts. Cord blood CFU-F derived fibroblasts have properties supporting hematopoiesis: They produce CSF (colony stimulating factor) to which fresh cord blood CFU-GM (colony forming units-granulocytic, monocytic) react by colony formation in a dose-response manner. In addition, fibroblast colonies discharge clonogenic round cells into the medium forming CFU-GM and CFU-F colonies in secondary methyl cellulose cultures. We conclude that fetal blood contains clonogenic stromal cells (CFU-F) that give rise to fibroblasts with properties of hematopoietic support.
