The progressive ankylosis gene (ank) is a transmembrane protein that transports intracellular pyrophosphate to the extracellular milieu. Human mutations of ank lead to craniometaphyseal dysplasia, a disease which is characterized by the overgrowth of craniofacial bones and osteopenia in long bones, suggesting that ANK plays a regulatory role in osteoblast differentiation. To determine the role ...
Previous studies have provided evidence for the existence of adult human bone marrow stromal stem cells (BMSSCs) or mesenchymal stem cells. Using a combination of cell separation techniques, we have isolated an almost homogeneous population of BMSSCs from adult human bone marrow. Lacking phenotypic characteristics of leukocytes and mature stromal elements, BMSSCs are non-cycling and constitutiv...
Introduction: Hematopoiesis is an on going process mammalian marrow system. A few cells from the nucleated cells of bone marrow are hematopoietic cells which include primary stem cells, precursor cells and progenitor cells. Primary stem cells and progenitor cells are able to produce colonies in culture medium (CFU-C) and irradiated mouse spleen (CFU-S). A hematopoietic cell is alive and act...
Approximately 20% of B-lineage acute lymphoblastic leukemias are not cured by traditional chemotherapy. The possibility was examined that residual leukemic cells that potentially contribute to relapse are harbored in association with fibroblastic stromal cells in the bone marrow. Modulation of cytarabine (Ara-C) and etoposide (VP-16) efficacy by bone marrow stromal cells in vitro was investigat...
The availability of cloned lines of bone marrow stromal cells could facilitate the analysis of their role in hemopoietic cell development. The 266AD cell line was isolated from a colony of lipid-accumulating bone marrow cells growing in a collagen gel. 266AD cells have subsequently been maintained by passage in tissue culture plastic flasks about every 10 days for greater than 10 mo. Subconflue...
This article concluded our serial studies on the therapeutic protective effects of modified bone marrow stromal cells on central nervous injury. Hope this will provide a prelusion of transition of central nervous disease treatment from experimental treatment to the idea of clinical application.
In vitro studies suggest that bone marrow endothelial cells contribute to multilineage hematopoiesis, but this function has not been studied in vivo. We used a Cre/loxP-mediated recombination to produce mice that lacked the cytokine receptor subunit gp130 in hematopoietic and endothelial cells. Although normal at birth, the mice developed bone marrow dysfunction that was accompanied by splenome...
