conclusions our findings showed that the treatment of flaps with bm-msc and aam transplantations significantly promoted flap survival compared to a control group. the viability of the flap was improved by combining bm-mscs with aam matrix scaffolds. materials and methods bm-mscs and aams were transplanted into subcutaneous tissue in the flap area. on the 7th postoperative day, the surviving fla...

objective: tendon never returns to its complete biological and mechanical properties after repair. bone marrow and, recently, adipose tissue have been used as sources of mesenchymal stem cells which have been proven to enhance tendon healing. in the present study, we compared the effects of allotransplantation of bone marrow derived mesenchymal stromal cells (bmscs) and adipose derived stromal ...

Mesenchymal stem cells (MSCs) show high expression of PD-L1. Exosomes can transmit signals between tumor and stromal cells; however, the effect tumor-derived exosomes on cell signaling pathways is unclear. The PD-L1 in bone marrow mesenchymal (BMMSCs) was detected by western blot RT-PCR. effects gastric cancer line-derived BMMSC migration conditioned medium from educated BMMSCs were analyzed. O...

conclusions large amounts of preclinical studies have been made of stem cells and there is an increasing interest to perform these studies within the human population but preclinical studies are insufficient; therefore, much more and efficient studies should be conducted to evaluate the efficacy and safety of stem cells. context musculoskeletal injuries may be painful, troublesome, life limitin...

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...

BACKGROUND Mesenchymal stromal cells are multipotent cells considered to be of great promise for use in regenerative medicine. However, the cell dose may be a critical factor in many clinical conditions and the yield resulting from the ex vivo expansion of mesenchymal stromal cells derived from bone marrow may be insufficient. Thus, alternative sources of mesenchymal stromal cells need to be ex...

spinal cord injury (sci) is a debilitating disease which leads to progressive functional damages. because of limited axonal regeneration in the central nervous system, there is no or little recovery expected in the patients. different cellular and molecular approaches were investigated in sci animal models. cellular transplantation of stem cells can potentially replace damaged tissue and provid...

background susceptibility-weighted imaging (swi) is extremely sensitive in the detection of superparamagnetic iron oxide (spio) nanoparticle-labeled cells. however, no study has compared molecular imaging for stem cell detection using swi and other mri pulse sequences. objectives this study aims to assess the sensitivity of swi in detecting spio nanoparticle-labeled, human bone marrow-derived m...

Phenotypic changes induced by extracellular vesicles have been implicated in mesenchymal stromal cell-promoted recovery of AKI. MicroRNAs are potential candidates for cell reprogramming toward a proregenerative phenotype. The aim of this study was to evaluate whether microRNA deregulation inhibits the regenerative potential of mesenchymal stromal cells and derived extracellular vesicles in a mo...

background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...
