Glucocorticoid-induced osteoporosis (GIOP) is a widespread clinical complication following glucocorticoid therapy. This irreversible damage to bone-forming and -resorbing cells is essential in the pathogenesis of osteoporosis. Autophagy is a physiological process involved in the regulation of cells and their responses to diverse stimuli, however, the role of autophagy in glucocorticoid-induced ...

Bone marrow stem cells (BMSCs) have the capacity to differentiate into mature cell types of multiple tissues. Thus, they represent an alternative source for organ-specific cell replacement therapy in degenerative diseases. In this study, we demonstrated that female rat BMSCs could differentiate into steroidogenic cells with the capacity for de novo synthesis of Estradiol-17 β (E2) under high gl...

Bone mesenchymal stem cells (BMSCs) are currently considered the optimal stem cells for biological pacemaker cell transformation. The cardiac‑specific transcription factor T‑Box protein 18 (TBX18) is essential for sinoatrial node (SAN) formation, particularly formation of the head region that generates the electrical impulses that induce heart contraction. The present study aimed to confirm the...

The extracellular matrix(ECM), which is primarily composed of collagens and proteoglycans, plays a key role in cell proliferation, differentiation, and migration and interactions between cells. In this study, we produced chitosan/gelatin/bone marrow stem cells-derived extracellular matrix(C/G/BMSCs-dECM) scaffolds via lyophilization and cross-linking, and chitosan/gelatin(C/G) scaffolds were us...

Aseptic loosening of artificial joints is the leading cause of failure for patients who receive total joint arthroplasty. Prior reports indicate that bone marrow mesenchymal stem cells (BSMC) are critical in the stabilization of implanted artificial joints, and that deregulated interaction between BMSCs and artificial joint derived particles is a risk factor for aseptic loosening with an unknow...

Objective(s): To investigate and test the hypotheses that TGF-β1 enhanced myocardial differentiation through Wnt/β-catenin pathway with rat bone marrow mesenchymal stem cells (BMSCs).Materials and Methods: Lentiviral vectors carrying the TGF-β1 gene were transduced into rat BMSCs firstly. Then several kinds of experimental methods were u...

BACKGROUND Demyelination is a common lesion in spinal cord injury, cell therapy is one of the approaches for replacing the lost oligodendrocytes. In this study, bone marrow stromal cells (BMSCs) have been transdifferentiated into oligodendrocyte-like cells (OLCs) and used in cytotherapy of contused spinal cords in rats. METHODS The BMSCs were collected from the rat long bones, and cultured an...

The study of bone marrow stromal cells (BMSCs) and the exosomes they secrete is considered promising for cancer therapy. However, little is known about the effect of donor age on BMSCs. In the present study, we investigated the therapeutic potential of BMSC exosomes derived from donors of different ages using an in vivo model of hypoxic bone marrow in multiple myeloma (MM). We found that donor ...

The technique of stem cells or hepatocytes transplantation has recently improved in order to bridge the time before whole-organ liver transplantation. In the present study, unfractionated bone marrow stem cells (BMSCs) were harvested from the tibial and femoral marrow compartments of male mice, which were cultured in Dulbecco's modified Eagle's medium (DMEM) with and without hepatocyte growth f...

The present study aimed to investigate the effects of bone marrow‑derived mesenchymal stem cells (BMSCs) that had been pretreated with pioglitazone and/or rosiglitazone on the growth and proliferation rate of MCF‑7 cells. The adhesive interaction between the BMSCs and the MCF‑7 cancer cells revealed that the pretreatment of BMSCs with a combination of two types of thiazolidinedione drug reduced...
