OBJECTIVE To compare the properties of human mesenchymal stem cells (MSCs) isolated from bone marrow, synovium, periosteum, skeletal muscle, and adipose tissue. METHODS Human mesenchymal tissues were obtained from 8 donors during knee surgery for ligament injury. After collagenase digestion or gradient-density separation, nucleated cells were plated at an(More)
Several reports describe that the explant culture of the trabecular bone after collagenase treatment produces mesenchymal stem cells (MSCs). However, the suspended cells had not been intensively examined concerning MSCs. We hypothesized that the cells would acquire the properties of MSCs during their expansion and therefore compared them with marrow(More)
BACKGROUND AND OBJECTIVES Nocturnal hypoxemia is highly prevalent among patients with CKD. Nocturnal hypoxemia contributes to systemic inflammation, oxidative stress, endothelial cell dysfunction, and activation of the renin-angiotensin system, which are common pathologic mechanisms of CKD progression. This study investigated whether nocturnal hypoxemia is(More)
BACKGROUND AND OBJECTIVES Obstructive sleep apnea (OSA) affects one of five adults in the general population. Although a high prevalence of OSA has been reported among dialysis patients, the association between nondialysis chronic kidney disease (CKD) and OSA has not been fully investigated. This cross-sectional study aimed to investigate the prevalence of(More)
OBJECTIVE Mesenchymal stem cells from synovium have a greater proliferation and chondrogenic potential than do those from bone marrow, periosteum, fat, and muscle. This study was undertaken to compare fibrous synovium and adipose synovium (components of the synovium with subsynovium) to determine which is a more suitable source for mesenchymal stem cells,(More)
There are increasing reports that mesenchymal stem cells (MSCs) are present in various tissues other than bone marrow, including synovium. Here we investigated the optimal conditions for in vitro chondrogenesis of human synovium-derived MSCs and compared these cells with bone marrow-derived MSCs, especially in terms of their chondrogenesis potential.(More)
Although previous studies in the general population showed that hypomagnesemia is a risk for cardiovascular diseases (CVD), the impact of magnesium on the prognosis of patients on hemodialysis has been poorly investigated. To gain information on this we conducted a nationwide registry-based cohort study of 142,555 hemodialysis patients to determine whether(More)
OBJECTIVE There is now growing evidence that magnesium (Mg) deficiency is implicated in type 2 diabetes and its complications. However, it has not been fully elucidated whether hypomagnesemia is a predictor of end-stage renal disease (ESRD) in type 2 diabetic nephropathy. RESEARCH DESIGN AND METHODS This retrospective cohort study included 455 chronic(More)
Thyroid hormones play an important role in cardiac electrophysiology. However, the regulation of cardiac ionic channels by thyroid hormones is still unclear. To evaluate the acute effect of 3,3',5-triiode-L-thyronine (T3) on inward rectifier potassium channel (IK1) action potentials, whole-cell IK1 currents and steady-state single IK1 currents were recorded(More)
Cell transplantation has shown to be a promising strategy to repair cartilage defects. Mesenchymal stem cells derived from synovium have been shown to be a superior cell source for cartilage regeneration to those from other mesenchymal tissues due to their higher rates of colony formation, proliferation potential with autologous serum, and in vitro/vivo(More)
