Hematopoietic cells differentiate in steps marked by the acquisition or loss of specific phenotypic characteristics. Human bone marrow cells that were responsive to the early-acting cytokines Kit ligand and interleukin-3 were forced to a metabolic death. The subfraction remaining represented 1 in 10(5) bone marrow mononuclear cells, were determined to be(More)
Identification of human hematopoietic stem cells and analysis of molecular mechanisms regulating their function require biological assays that permit differentiation in all hematopoietic lineages simultaneously. In this study, we established conditions that permit the joint expression of the B-lymphoid and myeloid potential from cord blood-derived(More)
Basic fibroblast growth factor or fibroblast growth factor-2 (FGF) has been shown to affect myeloid cell proliferation and hypothesized to stimulate primitive hematopoietic cells. We sought to evaluate the effect of FGF on hematopoietic stem cells and to determine if FGF mediated its effects on progenitor cells directly or through the induction of other(More)
The natural Cannabis sativa compounds, cannabidiol, cannabinol, δ 9- and δ 8-tetrahydrocannabinol, in that order of potency, decreased the susceptibility of rat dorsal hippocampus to seizure discharges caused by afferent stimulation. The drugs were effective following both intraperitoneal injection and topical application. They were more active, on a dose(More)
