We hypothesized that RNA interference to silence Nogo-66 receptor gene expression in bone marrow mesenchymal stem cells before transplantation might further improve neurological function in rats with spinal cord transection injury. After 2 weeks, the number of neurons and BrdU-positive cells in the Nogo-66 receptor gene silencing group was higher than in the bone marrow mesenchymal stem cell gr...

in the bone marrow, there are certain populations of stem cell sources with the capacity to differentiate into several different types of cells. ideally, cell transplants would be readily obtainable, easy to expand and bank, and capable of surviving for sufficient periods of time. bone marrow mesenchymal stem cells (bm-mscs) possess all of these characteristics. one of the most important benefi...

objective: allogeneic transplantation with umbilical cord blood (ucb) in adult recipients is limited mainly by a low cd34+ cell dose. to overcome this shortcoming, human placenta as a novel source of human mesenchymal progenitor cell (mpc)- unrestricted somatic stem cells (ussc)- was incorporated in an attempt to expand cd34+ cells from ucb. to provide a similar environment in vitro, we coated ...

Objective(s): Cells perform their functional activities by communicating with each other through endogenous substances and receptors. Post-translation, stem cells function properly in new host tissue by carrying specific cell surface receptors. We aimed to characterize muscarinic receptor subtypes in mesenchymal stem cells (MSCs) together with osteogenic and adipogenic...

Bone marrow microenvironment is fundamental for hematopoietic homeostasis. Numerous efforts have been made to reproduce or manipulate its activity to facilitate engraftment after hematopoietic stem cell transplantation but clinical results remain unconvincing. This probably reflects the complexity of the hematopoietic niche. Recent data have demonstrated the fundamental role of stromal and myel...

The bone marrow serves as a reservoir for different classes of stem cells. In addtion to haematopoietic stem cells the bone marrow comprises a population of marrow stromal cells or mesenchymal stem cells (MSCs). Stromal cells exhibit multilineage differentiation capacity, and are able to generate progenitors with restricted developmental potential, including fibroblasts, osteoblasts, adipocytes...

Background: This article reviews experimental and clinical studies in which neural injuries repaired with bone marrow stromal cells. History: Bone marrow contains two kinds of stem cells: hematopoietic and nonhematopoietic (stromal) stem cell. In vitro studies indicate that bone marrow stromal cells have the capacity of differentiation into other cells (such as neural cell) under treatment wit...

Up-regulation of CD4+CD25+CD127low/- regulatory T cells (Tregs) is a new target in the treatment of asthma. Human bone marrow mesenchymal stem cells can up-regulate CD4+CD25+CD127low/- regulatory T cells in vitro, meanwhile, heme oxygenase-1 (HO-1) plays an important role in the development and maintenance of CD4+CD25+ regulatory T cells. However the mechanism has not yet been adequately unders...
