Purpose: Co-culture systems of marrow derived mesenchymal stem cells (mMSCs) with mature chondrocytes have theoretically been considered as a putative way of MSCs chondrogenic differentiation. MSCs differentiated in this system could be used for transplantation purpose without of any need to their purification since the cells with which MSCs are co cultured are native cartilage cells. Despite o...
By Using the modeling of the mesenchymal (bone marrow) stem cell nanoparticles, the reinstatement of the immune system leads to the treatment of MS, result in the formation of a new immune system for the body by stem cell. The presence of stem cells promotes and strengthens myelination, and that, using simulation and 3D modeling, stem cells can be transmitted correctly to the target and place o...
Objective(s):Sea cucumber derived bioactive compound is considered efficient in treatment of bone disorders. This study was performed to evaluate the effect of this extract on differentiation of rat bone marrow mesenchymal stem cells (rBMMSc) into osteogenic lineage. Materials and Methods: Isolated rBMMSc were grown in DMEM supplemented with 10% FBS. The cells were exposed to different concen...
Intermittent PTH administration builds bone mass and prevents fractures, but its mechanism of action is unclear. We genetically deleted the PTH/PTHrP receptor (PTH1R) in mesenchymal stem cells using Prx1Cre and found low bone formation, increased bone resorption, and high bone marrow adipose tissue (BMAT). Bone marrow adipocytes traced to Prx1 and expressed classic adipogenic markers and high r...
The bone marrow niche represents a specialized environment that regulates mesenchymal stem cell quiescence and self-renewal, yet fosters stem cell migration and differentiation upon demand. An in vitro model that embodies these features would open up the ability to perform detailed study of stem cell behavior. In this paper we present a simple bone marrow-like niche model, which comprises of na...
Perivascular mesenchymal stem and progenitor cells (MSPCs) are critical for forming a healthy hematopoietic stem cell (HSC) niche. However, the interactions and influence of acute myelogenous leukemia (AML) stem cells with the microenvironment remain largely unexplored. We have unexpectedly found that neuropathy of the sympathetic nervous system (SNS) promotes leukemic bone marrow infiltration ...
Objective(s):Some evidence showed that calcitriol has an important role in regulating growth and differentiation of mesenchymal stem cells (MSCs). However, the interaction between mesenchymal stem cells and macrophage is not clear yet. The current study was done to investigate the in vitro effects of calcitriol on the interactions between bone marrow-derived MSCs and rat macrophages. Material...
introduction: mechanical stimulation of human mesenchymal stem cells has demonstrated changes in many cell behaviours such as adhesion, migration, growth and differentiation through mechanotransductive pathways. these include experiments on effect of nanotopography 1, shear stress, stiffness of extracellular matrix 2, strain, stress and acoustic wave energy 3 on cells. in this research we were ...

Irradiation induces bone injury by generating free radicals that adversely affect the microenvironment for Mesenchymal stem cells (MSCs) and damages bone marrow blood vessels. We wished to investigate the efficacy of antioxidant administration in protecting stem cell microenvironments and promoting bone marrow vasculature recovery after radiation treatment. The antioxidant ascorbic acid was adm...
