Regulatory Cells in the Bone Marrow
1976Regulation of the immune system has been attributed primarily to thymus-derived T cells (1,2). Here we present evidence that suppression can be mediated by another cell type, found in the bone marrow, that is neither a T cell nor a macrophage. Others have also shown that bone marrow-derived (B) cell suppression can inhibit both humoral and cell ...

In vitro chondrogenesis of bone marrow-derived mesenchymal progenitor cells.
Experimental Cell Research, 1998A culture system that facilitates the chondrogenic differentiation of rabbit bone marrow-derived mesenchymal progenitor cells has been developed. Cells obtained in bone marrow aspirates were first isolated by monolayer culture and then transferred into ...

Cellular Immunology, 1974
Abstract Mouse bone marrow (BM) contains cells capable of responding in vitro to the T cell mitogens, phytohemagglutinin (PHA) and concanavalin A (Con A). These responses are less vigorous than those of spleen cells. The optimal mitogen concentrations for BM cells are different from those for spleen cells; BM cells require twice as much ...

Ultrastructure of reticulum cells in the bone marrow
Cells Tissues Organs, 1978In this study the attempt was made to classify the reticulum cells of the bone marrow on the basis of electron-microscopic findings. The basis of the differentiation was the ability of the cells to phagocytize substances or not. For two cell types the intracytoplasmic filaments were used as distinctive marks.

Regulation of Constitutive Bone Marrow Cell Proliferation by Bone Marrow Suppressor Cells
International Archives of Allergy and Immunology, 1984Bone marrow (BM) cells have previously been shown to suppress specific immune responses of cells from peripheral lymphoid organs. The present report describes a suppressor cell present in normal rabbit BM, which regulated the constitutive proliferation of other BM cells.

Bone marrow as a potential source of hepatic oval cells.
Science, 1999Bone marrow stem cells develop into hematopoietic and mesenchymal lineages but have not been known to participate in production of hepatocytes, biliary cells, or oval cells during liver regeneration.

Bone marrow-derived cells and hypertension
Expert Review of Cardiovascular Therapy, 2010Although it is clear that inadequate perfusion underlies most of the organ dysfunction accounting for hypertension-related adverse outcomes, our understanding of the pathophysiologic mechanisms is still evolving. The most important approaches to improving vascular health include reducing injury to the vessel wall and enhancing mechanisms to repair ...

Importance of bone marrow cell dose in bone marrow transplantation
Clinical Transplantation, 1992The importance of the size of the infused marrow cell dose (MCD) was investigated in 274 patients undergoing allogeneic BMT between 1975 and 1990. Among those, 65 had acute myelogenous leukemia (AML), 79 acute lymphoblastic leukemia (ALL), 58 chronic myelogenous leukemia (CML) and 25 severe aplastic anemia (SAA).

Bone Reconstruction with Bone Marrow Stromal Cells
2006Bone marrow stromal/stem cells (BMSCs) are multipotent adult stem cells and have become the important cell source for cell therapy and engineered tissue repair. Their osteogenic differentiation potential has been well characterized in many in vitro studies.

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 & ...
