Bone mesenchymal stem cells (BMSCs) transplantation is a promising therapeutic approach for myocardial infarction (MI), but its application is limited by poor viability of BMSCs. In this study, we aimed to improve the survival of BMSCs by lentivirus vector mediated overexpression of integrin β1. In vitro study showed that integrin β1 overexpression could facilitate the proliferation of BMSCs un...

Objective Special hypoxic and hypertonic microenvironment in intervertebral discs (IVDs) decreases the treatment effect of cell transplantation. We investigated the hypothesis that hypoxic preconditioning (HP) could improve the therapeutic effect of bone mesenchymal stem cells (BMSCs) to IVD degeneration. Methods BMSCs from green fluorescent protein-transgenic rats were pretreated with cobalt...

Icariin has been identified to promote osteogenic differentiation of bone mesenchymal stem cells (BMSCs). However, whether icariin could enhance angiogenic factor expression of BMSCs, which may be vital for bone repair need to be explored. Moreover, how to construct a delivery system of icariin and the repair capability in the bone defect is still unknown. In present study, the effects of icari...

BACKGROUND Recent studies showed that bone marrow-derived mesenchymal stem cells (BMSCs) had risk of ectopic bone formation. In this study, we aimed to investigate the effect of growth and differentiation factor 6 (GDF-6) on the tenogenic differentiation of BMSCs in vitro, and then combined with small intestine submucous (SIS) to promote tendon regeneration in vivo. METHODS The BMSCs were iso...

OBJECTIVE Cerebral infarction, or ischemia brain stroke, is a common cerebrovascular disease. Bone marrow mesenchymal stem cells (BMSCs) are widely used to treating ischemia disease such as cardiac infarction. Ultrasonic microvesicles may help the targeting of exogenous factors via localized energy blast. Therefore, this study aims to investigate the effect of ultrasonic microvesicles on the ho...

To observe the therapeutic effect of rats with spinal cord injury through HBO and BMSCs transplantation. Jointly manufacture 60 SCI rat models, which shall be divided into the control group, BMSCs group and treatment group by adopting the random number table, 20 rats for each group. The HBO treatment shall be conducted to the rats in the treatment group for 2 times every day after molding; what...

Superparamagnetic iron oxide (SPIO) nanoparticles generate superparamagnetism, thereby resulting in an inhomogeneous local magnetic field, which shortens the T2 value on magnetic resonance imaging (MRI). The purpose of the present study was to use MRI to track bone marrow mesenchymal stem cells (BMSCs) labeled with SPIO in a rat model of myocardial infarction. The BMSCs were isolated from rats ...

Transplantation of bone marrow mesenchymal stem cells (BMSCs) protect against spinal cord ischemia/reperfusion injury (SCIRI). However, a large number of transplanted BMSCs often undergo apoptosis, which severely affects the treatment outcome. Previous studies have demonstrated that hypoxic preconditioning effectively increases the survival rate of BMSCs following transplantation, and increases...

The present study aimed to investigate the effects of human brain-derived neurotrophic factor (hBDNF) on the differentiation of bone marrow mesenchymal stem cells (MSCs) into neuron-like cells. Lentiviral vectors carrying the hBDNF gene were used to modify the bone marrow stromal cells (BMSCs) of Sprague-Dawley (SD) rats. The rat BMSCs were isolated, cultured and identified. A lentivirus bearin...

generation neural stem cells from neurosphere–derived bone marrow stem cells using bioactive substance atc. bone marrow cells (bmscs) were isolated from rat. bmscs cultured by dmem/f12 medium supplemented with 10% fetal bovine serum. these cells evaluated by specific markers of bmscs such as bioactive substance atc, b27. then bmscs differentionated in to neurosphere and divided in two groups wh...
