Objective(s): Intracerebral injection of bone marrow stromal cells (BMSCs) is being investigated as a therapeutic tool to prevent Alzheimer's disease (AD). Our aim was to investigate the effects of BMSCs by intrathecal injection in AD rat model. Materials and Methods: BMSCs were obtained from the bone marrow of Wistar rat and transplanted into AD rat model via intrathecal injection. The rat mod...

PURPOSE Several signaling pathways have been shown to regulate the lineage commitment and terminal differentiation of bone marrow stromal cells (BMSCs). Bone morphogenetic protein (BMP) signaling has important effects on the process of skeletogenesis. In the present study, we tested the role of bone morphogenetic protein receptor (BMPR) in the osteogenic differentiation of rat bone marrow strom...

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...

In this study, we sought to investigate the expression of microRNA (miR)-214 on the osteogenic differentiation of bone marrow‑derived mesenchymal stem cells (BMSCs) and explore the possible underlying mechanisms. We found that the overexpression of miR‑214 effectively promoted the adipocyte differentiation of BMSCs in vitro, reduced alkaline phosphatase (ALP) activity and the gene expression of...

BACKGROUND AND PURPOSE The therapeutic potential of bone marrow stromal cells (BMSCs) has been demonstrated in different models of stroke. Although it is well established that BMSCs selectively migrate to the site of brain injury, the mechanisms underlying this process are poorly understood. This study addresses the hypothesis that selectins mediate the recruitment of BMSCs into the postischemi...

AIMS Some environmental insults, such as fine particulate matter (PM) exposure, significantly impair the function of stem cells. However, it is unknown if PM exposure could affect the population of bone marrow stem cells (BMSCs). The present study was to investigate the effects of PM on BMSCs population and related mechanism(s). MAIN METHEODS PM was intranasally distilled into male C57BL/6 mi...

Hypothermia therapy has a positive effect on patients with severe brain injury. Recent studies have shown that mild hypothermia increases the survival of bone marrow-derived mesenchymal stem cells (BMSCs) in a hypoxic environment; however, the underlying mechanisms are not yet fully understood. Small ubiquitin-like modifiers (SUMOs) are sensitive to temperature stress reactions and are consider...

The aim of this study was to observe the dynamic expression of osteopontin, type I collagen, and osteocalcin genes during the differentiation of bone marrow mesenchymal stem cells (BMSCs) into osteoblasts and confirm whether BMSCs can differentiate and mature into osteoblasts. A healthy, 2-month-old Altay tailed sheep was obtained, and 10 mL bone marrow was extracted from the posterior superior...

BACKGROUND AND PURPOSE We compared the effect of treatment of stroke with bone marrow stromal cells from stroke rats (Isch-BMSC) and normal rats (Nor-BMSC) on functional outcome. METHODS Isch-BMSCs and Nor-BMSCs were intravenously injected into rats 24 hours after middle cerebral artery occlusion. To test the mechanism of Isch-BMSC-enhanced neurorestoration, Isch-BMSC and Nor-BMSC cultures we...

Premature ovarian failure (POF) is a long-term adverse effect of chemotherapy treatment. However, current available treatment regimens are not optimal. Emerging evidence suggests that bone marrow-derived mesenchymal stem cells (BMSCs) could restore the structure and function of injured tissues, but the homing and restorative effects of BMSCs on chemotherapy injured ovaries are still not clear. ...
