BACKGROUND: Stem cell therapy in small animal medicineis still in its infancy and few in vitro and in vivo research projectsregarding animal Mesenchymal Stem Cells (MSCs) have beencarried out. On the other hand, Cell tracking is the first step of thecell-based therapies and is essential to recognize cell fate posttransplantation. OBJECTIVES: The aim of this study was toisolate, characterize, an...

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. materials...

The development of biomaterial surfaces possessing the topographical cues that can promote mesenchymal stem cell recruitment and, in particular, those capable of subsequently directing osteogenic differentiation is of increasing importance for the advancement of tissue engineering. While it is accepted that it is the interaction with specific nanoscale topography that induces mesenchymal stem c...

introduction: mesenchymal stem cells (mscs) hold great promise in the field of regenerative medicine.although originally isolated from bone marrow, mscs have since been obtained from a variety of adult and neonatal tissues including the adipose tissue. stemness and multipotential features of mesenchymal stem cells (msc) has been highlighted in many studies but there are many dark aspects in exc...

Adult mesenchymal stem cells with multilineage differentiation potentially exist in the bone marrow, but have also been isolated from the peripheral blood. The differentiation of stem cells after leaving their niches depends predominately on the local milieu and its new microenvironment, and is facilitated by soluble factors but also by the close cell-cell interaction in a three-dimensional tis...

Somatic tissue engraftment was studied in BXSB mice treated with mesenchymal stem cell transplantation. Hosts were conditioned with nonlethal radiation prior to introducing donor cells from major histocompatibility complex-matched green fluorescent protein transgenic mice. Transplant protocols differed for route of injection, ie, intravenous (i.v.) versus intraperitoneal (i.p.), and source of m...

Background: Mesenchymal stem cells are non-hematopoietic stromal cells that are used in the treatment of many chronic and autoimmune diseases by modulating the immune system. Due to the limitations of using autologous mesenchymal stem cells, the use of allogeneic stem cells is a promising therapeutic approach in the treatment of immunological disorders. This study aimed to investigate the abili...

multiple sclerosis is an inflammatory disease of the central nervous system in which t cells experience a second phase of activation, which ultimately leads to axonal demyelination and neurological disability. the recent advances in stem cell therapies may serve as potential treatments for neurological disorders. there are broad types of stem cells such as neural, embryonic, mesenchymal and hem...

AIMS Adult human bone marrow contains a population of mesenchymal stem cells (MSC) that contributes to the regeneration of tissues such as bone, cartilage, muscle, tendon, and fat. In recent years, it has been shown that functional stem cells exist in the adult bone marrow, and they can contribute to renal remodelling or reconstitution of injured renal glomeruli, especially mesangial cells. The...
