The architecture of bone marrow cell populations
The International Journal of Cell Cloning, 1990Marrow is a loosely bound tissue in which hemopoiesis has frequently been considered to be randomly distributed. The case is presented, however, for an organized and structured marrow in which close relationships exist between hemopoietic tissue and a regulatory microenvironment.

Bone Marrow and B Cell Differentiation
1982Recent progress in the B lymphocyte field has been rapid. However, the revelations of immunoglobulin gene expression, genesis of antibody diversity and hybridoma technology all serve to highlight outstanding questions conerning the in vivo organization of B lymphocytes and their progenitors.

Stem cells as bone marrow residents
Biology Bulletin, 2011In addition to being a source of hematopoietic and mesenchymal stromal cells, bone marrow is known to be the source of stem cell populations, which express pluripotential markers and are capable of differentiating into cells of three blastophyllums (ectoderm, mesoderm, and endoderm).

The Radiosensitivity of Rat Bone-marrow Cells
International Journal of Radiation Biology and Related Studies in Physics, Chemistry and Medicine, 1970SummaryThe radiosensitivity of rat bone-marrow cells was determined by the spleen-colony technique. When the marrow cells were irradiated in vivo, the D0 was 97 rads, and the extrapolation number was 5·2. Similar results were obtained after in vitro irradiation: D0 = 94 rads, and extrapolation number = 4·1.

Counting Cells in Human Bone Marrow
American Journal of Clinical Pathology, 1974A method for estimation of human bone marrow cellularity is described. After bone marrow puncture, the aspirate is sieved, and the retained particles flushed with cold plasma. They are then aspirated in a glass capillary tube of known volume, and after centrifugation the packed material is measured.

Osteogenesis and Bone-Marrow-Derived Cells
Blood Cells, Molecules, and Diseases, 2001This paper addresses some of the important aspects of stem cell commitment to the bone cell lineage examining the various types of precursor cells, their responses to cytokines and other extracellular influences, and recent observations on the biochemical and molecular control of lineage-specific gene expression.
