Osteoporosis (OP) is considered a complex disease with a strong genetic impact, mainly affecting post-menopausal women and is also a common cause of fracture. Elucidating the molecular mechanisms that regulate the osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) is crucial to developing treatment strategies to combat OP. In the present study, we found that ectopi...

Background: Spinal cord injury (SCI) is a serious traumatic disease of the central nervous system, and there currently no effective treatment for SCI because its complicated pathophysiology. Bone marrow mesenchymal stem cells (BMSCs) have multidirectional differentiation abilities. Our study aims to explore effects bone morphogenetic protein 7 (BMP-7)-modified BMSCs transplantation on repair in...

introduction: there are the evidences to suggest that bone marrow stromal cells (bmscs) not only differentiate into mesodermal cells, but also adopt the fate of endodermal and ectodermal cell types. bmscs can be a valuable cell source as an autograph for clinical application involving regeneration of the central nervous system. bone marrow stromal cells can be expanded rapidly in vitro and have...

BACKGROUND We aimed to explore (i) the short-term retention of intramedullary implanted mesenchymal stem cells BMSCs and (ii) their impact on the bone blood flow and metabolism in a rat model of hindlimb irradiation. METHODS Three months after 30 Gy irradiation, fourteen animals were referred into 2 groups: a sham-operated group (n = 6) and a treated group (n = 8) in which ¹¹¹In-labelled BMSC...

The purpose of this study was to evaluate a thin gelatin hydrogel membrane containing β-tricalcium phosphate (G-TCP) for use in guided bone regeneration, a technique that we developed. G-TCP membranes were fabricated from gelatin and β-TCP powder, freezedried, and cross-linked by heating. The resulting G-TCP membranes were as thin as collagen membranes, with high mechanical integrity. Prolifera...

This study investigated the effect of bone marrow mesenchymal stem cells (BMSCs) on the motor pathway in the transient ischemic rat brain that were transplanted through the carotid artery, measuring motor-evoked potential (MEP) in the four limbs muscle and the atlantooccipital membrane, which was elicited after monopolar and bipolar transcortical stimulation. After monopolar stimulation, the la...

Finding the optimal recombinant adeno-associated virus (rAAV) serotypes for efficient as well as tissue specific transduction has become imperative for successful gene therapy. We used rat condylar chondrocytes, osteoblast-like cell line UMR106 and bone marrow stromal cells (BMSCs) to evaluate the transduction efficiency of different rAAV serotypes in vitro; hoping to establish an efficient in ...

Radiation therapy for oral and maxillofacial tumors could damage bone marrow stromal cells (BMSCs) in jaw, which caused dental implant failure. However, how radiation affects BMSCs on SLA (sandblasted with large-grits, acid-etched) surfaces is still unknown. The aim of this study was to investigate effect of different dose of γ-radiation on BMSCs on SLA and PT (polished titanium) surfaces. Rat ...

BACKGROUND Since the osteogenic potential of bone marrow derived mesenchymal stem cells (BMSCs) becomes reduced with passage, establishment of culture condition that permit the rapid expansion of BMSCs while retaining their potential for differentiation is needed for clinical application. Bone morphogenetic proteins stimulate osteogenic differentiation in mesenchymal progenitor cells as well as...

Acute pancreatitis (AP) is a common acute abdominal disease, 10%-20% of which can evolve into severe acute pancreatitis (SAP). SAP causes significant morbidity and mortality. RhoA/Rho kinase is activated in SAP. Bone marrow-derived mesenchymal stem cells (BMSCs) have been demonstrated to be a therapeutic role in SAP, but the underlying molecular mechanism is still unclear. This study was design...
