Long-term human bone marrow cultures.
Pronlonged in vitro growth of murine bone marrow has been achieved using a flask culture system. We report the adaption of the technique to the growth of human bone marrow. In this system, CFU-GM and CFU-E are maintained for 4-9 wk. Morphologically recognizable granulopoiesis occurs for 4-6 wk and erythropoiesis for 1.5-2.5 wk. Functional T lymphocytes are maintained for at least 5 wk. The adhe...
متن کاملRegulation of megakaryopoiesis in long-term murine bone marrow cultures.
Megakaryocytes and their precursor cells were sustained in mouse bone marrow suspension cultures for over 4-6 wk. Megakaryocyte precursor cells were detected by their capacity to form colonies of megakaryocytes in semisolid agar cultures. Colony formation was dependent on the presence of medium conditioned by a myelomonocytic leukemic cell line (WEHI-3CM). Megakaryocytes from the liquid and sem...
متن کاملHuman immunodeficiency virus infection impairs hemopoiesis in long-term bone marrow cultures: nonreversal by nucleoside analogues.
Hematologic abnormalities are often seen in patients infected with human immunodeficiency virus (HIV). The effect of HIV infection of bone marrow stroma on support of uninfected CD34 progenitor cells in long-term bone marrow culture (LTBMC) was investigated. Results show that HIV-infected bone marrow stroma was unable to adequately support CD34 progenitor cells in vitro. Zidovudine or didanosin...
متن کاملInhibition of osteoclast-like cell formation by bisphosphonates in long-term cultures of human bone marrow.
Bisphosphonates inhibit bone resorption in vivo and in vitro by unknown mechanisms. The effect of bisphosphonates on the formation of osteoclasts from their mononuclear hematopoietic precursors was investigated using human long-term marrow cultures in which multinucleated cells form that express most of the known features of the osteoclast phenotype (e.g., bone resorption, tartrate-resistant ac...
متن کاملDiethyldithiocarbamate induction of cytokine release in human long-term bone marrow cultures.
Diethyldithiocarbamate (DDTC) is a biochemical modulating agent that protects murine bone marrow progenitor cells from the cytotoxicity of a variety of cancer chemotherapeutic agents. However, the mechanism of this protection is not well understood. Long-term human bone marrow cultures (LTBMC) were established and at day 17 treated with 30 mumol/L DDTC for 1 hour, after which DDTC was removed a...
