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...

BACKGROUND Platelet-rich plasma (PRP) can provide an assortment of growth factors, but how PRP effects bone regeneration is still unknown. The aim of the study was to explore an optimal method of using PRP and bone marrow stromal cells (BMSCs). METHODS An in vitro experiment was first conducted to determine an appropriate quantity of PRP. BMSCs were cultured with PRP of different concentratio...

Glial cell line-derived neurotrophic factor (GDNF) is one of the most important proteins playing a pivotal role in growing and repairing of the nervous system. GDNF therapy is one of the suggested options in the treatment of neurodegenerative diseases. Limitations in the viral gene delivery and its side effects after therapy have encouraged us to use a non-viral method one for this purpose. We ...

objective(s):various methods for repairing bone defects are presented. cell therapy is one of these methods. bone marrow stromal cells (bmscs) seem to be suitable for this purpose. on the other hand, lots of biomaterials are used to improve and repair the defect in the body, so in this study we tried to produce a similar structure to the bone by the chitosan and hydroxyapatite. materials and me...

HSPA1A, which encodes cognate heat shock protein 70, plays important roles in various cellular metabolic pathways. To investigate its effects on osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs), its expression level was compared between undifferentiated and differentiated BMSCs. Rat HSPA1A overexpression in BMSCs increased osteoblast-specific gene expression, alkaline ph...

INTRODUCTION Transplantation of bone marrow stromal cells (BMSCs) or Schwann cells (SCs) can increase axonal regeneration in peripheral nerve injuries. Based on our previous investigations, the goal of the present work was to examine the individual and synergistic effects of the two different cell types in sciatic nerve injury. We pursued to evaluate the effects of BMSCs and SCs co-transplantat...

Abstract Objectives This study aims to investigate whether apoptosis repressor with caspase recruitment domain (ARC) could promote survival and enhance osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs). Materials methods The lentivirus transfection method was used establish ARC-overexpressing BMSCs. CCK-8 detect cell proliferation. BD Pharmingen™ APC Annexin V Apo...

Abstract Objective We aimed to investigate the therapeutic effects of Moringa oleifera leaf extracts on osteogenic induction rat bone marrow mesenchymal stem cells (BMSCs) following peroxidative damage and explore underlying mechanisms. Methods Conditioned medium was used induce differentiation BMSCs, which were treated with H 2 O , extracts-containing serum, or phosphatidyl inositol-3 kinase (...

traumatic central nervous system injuries lead to a severe and permanent neurological deficit. oligodendrocytes (olcs) are vulnerable to damage in a variety of neurologic diseases. although no effective therapeutic option is currently available, recent other studies have shown that cell therapeutic strategies hold promise to enhance functional recovery after injury. the aim of this study is to ...

background: bone marrow and umbilical cord stromal cells are multipotential stem cells that have the ability to produce growth factors that play an important role in survival and generation of axons. the goal of this study was to evaluate the effects of the two different mesenchymal stem cells on peripheral nerve regeneration. materials and methods: in this experimental study, a 10 mm segment o...
