The architecture of bone marrow cell populations

The International Journal of Cell Cloning, 1990
Marrow 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.

Counting Cells in Human Bone Marrow [PDF]

American Journal of Clinical Pathology, 1974
A 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.

Bone Marrow Cells and Myocardial Regeneration

International Journal of Hematology, 2004
Hematopoietic stem cell (HSC) plasticity and its clinical application have been studied profoundly in the past few years. Recent investigations indicate that HSC and other bone marrow stem cells can develop into other tissues. Because of the high morbidity and mortality of myocardial infarction and other heart disorders, myocardial regeneration is a ...

Stem cells as bone marrow residents

Biology Bulletin, 2011
In 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).

Bone marrow cell separation studies

Experimental Cell Research, 1960
Abstract Differential gradient centrifugation of bone marrow cell suspensions in bovine serum albumin produced layers of mixed cell types. Each layer was capable isologously of promoting survival of heavily irradiated (C57BL × 101)F 1 mice; none was more effective than fresh whole bone marrow.

Stem cell differentiation in the bone-marrow

Immunology Today, 1981
Even in the absence of antigenic challenge, the adult immune system is in a state of constant flux and each day receives large numbers of newly formed lymphocytes. The bone-marrow is vital to this continuous renewal, both in its regulation and because it is the direct source of B cells in normal animals and the indirect source of T cells, which are ...

Cell counts of mouse bone marrow

Life Sciences, 1964
Abstract An electronic cell counter has been used to quantify the numbers of bone marrow cells in the mouse tibia. Preliminary experiments have revealed that a single injection of a bacterial endotoxin causes a significant decrease in the absolute numbers of mature neutrophils from the bone marrow after 5 hours and a partial recovery to normal values

Osteogenesis and Bone-Marrow-Derived Cells

Blood Cells, Molecules, and Diseases, 2001
This 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.
