Bone marrow transplantation (BMT) is an effective therapeutic strategy for leukaemic malignancies and depressed bone marrow following cancer. However, its side effects on kidneys have been reported. Some drugs and irradiation are also suggested to be nephrotoxic. It is well known that haemolytic uraemic syndrome (HUS) after BMT develops as late-onset BMT nephropathy. Cyclosporine A (CsA) is a possible cause. Radiation nephropathy shows changes that are similar to the histology of HUS. These findings suggest that endothelial damage is closely associated with the pathogenesis of post-BMT nephropathy. Recently, some patients have developed glomerulonephritis accompanied by graft-versus-host disease (GVHD) after BMT. In these patients immune deposits are found mainly in subepithelium and mesangium equal to those of secondary membranous glomerulonephritis. A murine experimental model of GVHD manifests similar symptoms and histological changes to those of actual patients and may suggest the pathogenesis of glomerulonephritis.

An 8 yr old, male, mixed-breed dog was presented with a 2 mo history of progressive weakness, worsened in the last 2 days before examination. Neurological examination revealed ambulatory tetraparesis, ataxia, and proprioceptive deficits in all four limbs. Menace response was reduced in the right eye and discomfort was detected on neck manipulation.

Polymer/ceramic nanocomposites integrated the advantages of both polymers and ceramics for a wide range of biomedical applications, such as bone tissue repair. Here, we reported triphasic poly(lactic--glycolic acid) (PLGA, LA/GA = 90:10) nanocomposites with improved dispersion of hydroxyapatite (HA) and magnesium oxide (MgO) nanoparticles using a process that integrated the benefits of ultrasonic energy and dual asymmetric centrifugal mixing. We characterized the microstructure and composition of the nanocomposites and evaluated the effects of the HA/MgO ratios on degradation behavior and cell-material interactions.

Osteoporosis, affecting the entire skeletal system, can cause bone mass to diminish, thereby reducing bone strength and elevating fracture risk. Fracture nonunion and bone defects are common in patients with fractures, and pain and loss of function may cause serious distress. The search for a new therapeutic strategy is essential because of the limited therapeutic options available.

Background: Liver fibrosis is caused by chronic toxic or cholestatic liver injury. Fibrosis results from the recruitment of myeloid cells into the injured liver, the release of inflammatory and fibrogenic cytokines, and the activation of myofibroblasts, which secrete extracellular matrix, mostly collagen type I. Hepatic myofibroblasts originate from liver-resident mesenchymal cells, including HSCs and bone marrow-derived CD45+ collagen type I+ expressing fibrocytes.

Osteoporosis is characterized by decreased bone mass and accumulation of adipocytes in the bone marrow. The mechanism underlying the imbalance between osteoblastogenesis and adipogenesis in bone marrow mesenchymal stem cells (BMSCs) remains unclear. We found that ALG5 was significantly downregulated in BMSCs from osteoporotic specimens.
