pubmed:abstractText
A diploid fibroblastoid cell strain, termed "ST-1," has been established from a long-term liquid culture of human fetal liver cells. ST-1 cells are nonphagocytic, nonspecific esterase negative and do not possess factor VIII-related antigen but stain with antibodies specific for fibronectin and type I collagen. The ST-1 cells produce nondialyzable hemopoietic growth factors capable of stimulating the development of erythroid bursts, mixed granulocyte-macrophage colonies, pure granulocyte colonies, and pure macrophage colonies. These factors are active on both human fetal liver and human adult bone marrow progenitors. When liquid cultures of human fetal liver hemopoietic progenitors are established with a preformed monolayer of ST-1 cells, the yields of nonadherent cells, erythroid progenitors, and myeloid progenitors are greatly increased. These studies demonstrate that the fibroblastoid ST-1 cells support hemopoiesis in vitro and may be a critical element in the stromal microenviroment in vivo.
