Bone marrow-derived cells (BMCs) have been implicated as a modifiers of vascular growth either directly by transdifferentiation into endothelial cells (ECs) or indirectly through growth factor release. To examine these possibilities under physiological conditions, we developed a model of hypoxia-mediated angiogenesis in the mouse spinotrapezius muscle. This allows whole-mount analysis; therefor...

It is now recognized that transplantation of bone marrow cells (BMCs) into infarcted hearts has the capacity to improve the cardiac function through paracrine effects. However, detailed expression levels of paracrine factors in BMCs in infarcted hearts are poorly described. By use of laser capture microdissection combined with real-time PCR, we depicted the expression profiles of paracrine fact...

OBJECTIVE Transplantation of bone marrow-derived mononuclear cells (BMC) may be suitable to prevent myocardial remodeling and improve left ventricular function after myocardial infarction. However, it is unknown whether or not cardiomyocytes and BMCs can form functioning cell-to-cell coupling and develop adequate electrophysiological properties. METHODS BMCs were isolated from minipig leg bon...

OBJECTIVES The aim of this study was to identify an association between the quality and functional activity of bone marrow-derived progenitor cells (BMCs) used for cardiovascular regenerative therapies and contractile recovery in patients with acute myocardial infarction included in the placebo-controlled REPAIR-AMI (Reinfusion of Enriched Progenitor cells And Infarct Remodeling in Acute Myocar...

BACKGROUND Cell-based therapy shows promise in treating peripheral arterial disease (PAD); however, the optimal cell type and long-term efficacy are unknown. In this study, we identified a novel subpopulation of adult progenitor cells positive for CD34 and M-cadherin (CD34⁺/M-cad⁺ BMCs) in mouse and human bone marrow. We also examined the long-lasting therapeutic efficacy of mouse CD34⁺/M-cad⁺ ...

Bacterial microcompartments (BMCs) are proteinaceous organelles involved in both autotrophic and heterotrophic metabolism. All BMCs share homologous shell proteins but differ in their complement of enzymes; these are typically encoded adjacent to shell protein genes in genetic loci, or operons. To enable the identification and prediction of functional (sub)types of BMCs, we developed LoClass, a...

OBJECTIVE Angiographic indexes of restenosis after coronary stent placement in patients show a bimodal pattern suggesting the existence of two populations with different risk of restenosis. This is reflected in the arterial remodeling response of inbred mouse strains arguing for a genetic control of the mechanisms leading to lumen narrowing. As bone marrow-derived cells (BMCs) contribute to vas...

It has been reported that granulocyte-colony stimulating factor (G-CSF) and granulocyte-macrophage-colony stimulating factor (GM-CSF) can mobilize endothelial progenitor cells (EPCs) in bone marrow cells (BMCs) into peripheral blood (PB) in vivo. Previously, we also reported that macrophage-colony stimulating factor (M-CSF) can mobilize EPCs into PB, which results in the rapid recovery of blood...

Suppressor of cytokine signaling 3 (SOCS3) expression in bone marrow cells (BMC) was up-regulated upon exposure to interleukin 6, lipopolysaccharide, or tumor-associated factors. But, how the up-regulated SOCS3 affects differentiation of BMCs is incompletely characterized. Here, we showed that SOCS3 promoted BMCs to intently differentiate into CD8 T cells. Importantly, lung can be as one athymu...

Ischemic acute kidney injury (AKI) is the most key pathological event for accelerating progression to chronic kidney disease through vascular endothelial injury or dysfunction. Thus, it is critical to elucidate the molecular mechanism of endothelial protection and regeneration. Emerging evidence indicates that bone marrow-derived cells (BMCs) contribute to tissue reconstitution in several types...
