To identify cells with potential antileukemia activity following bone marrow transplantation. we have monitored immunologic reconstitution in a patient with acute lymphocytic leukemia in second remission who received intensive chemotherapy and total body irradiation followed by infusion of albogeneic histocompatible marrow. Prior to transplantation. donor bone marrow cells were depleted of T ly...

Bone marrow mesenchymal stem cells can differentiate into neurons and astrocytes after transplantation in the spinal cord of rats with ischemia/reperfusion injury. Although bone marrow mesenchymal stem cells are known to protect against spinal cord ischemia/reperfusion injury through anti-apoptotic effects, the precise mechanisms remain unclear. In the present study, bone marrow mesenchymal ste...

Haematopoietic stem cell transplantation remains the treatment of choice for a variety of benign and malignant blood disorders.1 In this modality Haematopoietic stem cell transplantation is the intravenous infusion of haematopoietic stem and progenitor cells to re-establish marrow function in patients with damaged or defective marrow. The procedure is called Bone Marrow Transplantation (BMT) if...

Adult bone marrow-derived cells can participate in muscle regeneration after bone marrow transplantation. In recent studies a single hematopoietic stem cell (HSC) was shown to give rise to cells that not only reconstituted all of the lineages of the blood, but also contributed to mature muscle fibers. However, the relevant HSC derivative with this potential has not yet been definitively identif...

Objective: The aim of this work was to explore the therapeutic effect of bone marrow-derived mesenchymal stem cells transplantation in SD rats’ ischemic hind limb. Methods: Ligation of the abdominal aorta beneath the renal artery, the lumbar artery and the iliolumbar artery, was performed to obtain the hindlimb ischemia model in female SD rats. Amplified and purified bone marrow-derived mesench...

Ischemic type biliary lesion (ITBL) is frequently occurred after orthotopic liver transplantation and severely affects patients’ survival rate. The pathogenesis of ITBL is still unclear yet, but has been suggested to be related with multiple factors including ischemia time of donor liver, reperfusion damage and immune factors. Complete ischemia model of intrahepatic biliary tract was establishe...

The multipotent nature of skeletal muscle-derived side population cells is demonstrated by their myogenic and hematopoietic potential in vivo. However, whether muscle side population cells are derived from the bone marrow is unclear. To study the long-term contribution of the hematopoietic system to muscle side population, whole bone marrow cells from Ly5.1 males or from e-GFP transgenic male m...

Bone marrow-Derived cells have been proposed to form new vessels or at least incorporate into growing vessels in adult organisms under certain physiological and pathological conditions. We investigated whether bone marrow-Derived cells incorporate into vessels using mouse models of hindlimb ischemia (arteriogenesis and angiogenesis) and tumor growth. C57BL/6 wild-type mice were lethally irradia...

Human umbilical cord blood (CB) has attracted much attention as a reservoir for functional hematopoietic stem and progenitor cells, and, recently, as a source of blood-borne fibroblasts (CB-BFs). Previously, we demonstrated that bone marrow stromal cell (BMSC) and CB-BF pellet cultures make cartilage in vitro Furthermore, upon in vivo transplantation, BMSC pellets remodelled into miniature bone...
