Osteogenesis in transplants of bone marrow cells
Development, 1966ABSTRACT After heterotopic (e.g. subcutaneous) transplantation of bone marrow, haemopoiesis in the graft ceases; reticular tissue develops instead, and later bone is formed (Denis, 1958). The result can be achieved by grafting either free pieces of bone marrow or those placed in diffusion chambers (Petrakova, Tolmacheva & ...

Bone Marrow-Derived Dendritic Cells
2013While much is understood about dendritic cells and their role in the immune system, the study of these cells is critical to gain a more complete understanding of their function. Dendritic cell isolation from mouse body tissues can be difficult and the number of cells isolated small.

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.

VERSATILE STEM CELLS IN BONE MARROW
The Lancet, 1982The question of whether there is a single pluripotent haemopoietic stem cell or a variety of stem cells each with a capacity for self-replication is still unresolved. Evidence from radiation-chimaeras and from patients with marrow grafts indicates that haemopoietic stem cells are not a homogeneous population.

Bone marrow microenvironment of MPN cells
2021In this chapter, we will discuss the current knowledge concerning the alterations of the cellular components in the bone marrow niche in Myeloproliferative Neoplasms (MPNs), highlighting the central role of the megakaryocytes in MPN progression, and the extracellular matrix components characterizing the fibrotic bone marrow.

Bone Marrow and B Cell Differentiation [PDF]
, 1982 Recent 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.

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.

T‐CELL DEPLETION OF HUMAN BONE MARROW
International Journal of Immunogenetics, 1989SUMMARYThe myelo‐ablative effects of high‐dose therapy for refractory cancer can be overcome by the transplantation of bone marrow from an HLA‐matched normal donor. Suitable donors are available for only one patient in three, and even minor disparities at HLA loci can produce graft‐versus‐host disease (GvHD) in transplant recipients.

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, 2004Hematopoietic 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 ...
