In recent years it has been shown that the therapeutic benefits of human mesenchymal stem/stromal cells (hMSCs) in the Central Nervous System (CNS) are mainly attributed to their secretome. The implementation of computer-controlled suspension bioreactors has shown to be a viable route for the expansion of these cells to large numbers. As hMSCs actively respond to their culture environment, ther...
Gene amplifications are an attribute of tumor cells and have for long time been overlooked in normal cells. A growing number of investigations describe gene amplifications in normal mammalian cells during development and differentiation. Possibly, tumor cells have rescued the gene amplification mechanism as a physiological attribute of stem cells. Here, we investigated human mesenchymal stem ce...
Human mesenchymal stem cell (hMSC) resistance to the apoptotic effects of chemotherapeutic drugs has been of major interest, as these cells can confer this resistance to tumor microenvironments. However, the effects of internalized chemotherapeutics upon hMSCs remain largely unexplored. In this study, cellular viability and proliferation assays, combined with different biochemical approaches, w...

Fluorescent labeling of human mesenchymal stem cells (hMSCs) is essential for their study in vitro and in vivo. Here, we report a new chemical biodelivery method for labeling hMSCs using a series of very efficient and highly versatile thiophene-based fluorescent dyes. Such conjugates contribute to a stable and viable labeling of hMSCs and constitute a promising strategy for in vivo applications.
The ionization feedback from HII regions modifies the properties of high-mass starless clumps (HMSCs, several hundred to a few thousand solar masses with size ~0.1-1 pc), such as temperature and turbulence, on clump scale. question whether presence core-scale fragmentation star formation in HMSCs remains be explored. We aim investigate difference 0.025 pc-scale between candidate that are strong...
Since 2004, when a case report describing the use of human mesenchymal stem cells (hMSCs) infusion as a therapy for GVHD after bone marrow transplantation, a new perspective in MSC function emerged. Since then hMSCs immunomodulatory potential became the target of several studies. Although great progress has been made in our understanding of hMSCs, their effect on T cell remains obscure. Our stu...
Bone marrow-derived mesenchymal stem cells (MSCs) have been reported to migrate to brain lesions in experimental models of ischemia, tumors, and neurodegenerative diseases and to ameliorate functional deficits. In this study, we attempted to evaluate the therapeutic potential of MSCs for treating prion diseases. Immortalized human MSCs (hMSCs) that express the LacZ gene were transplanted into t...
BACKGROUND To address the challenge of treating critical sized intercalary defects, we hypothesized that under physiologic cyclic loading, autografts, allografts, and scaffolds loaded with and without human mesenchymal stem cells (hMSCs) would have different biomechanical characteristics. METHODS Using a rat femoral defect model, 46 rats were assigned to four groups, ie, autograft (n = 12), a...
Cardiac cell therapies involving bone marrow-derived human mesenchymal stem cells (hMSCs) have shown promising results, although their mechanisms of action are still poorly understood. Here, we investigated direct interactions between hMSCs and cardiomyocytes in vitro. Using a genetic Ca(2+) indicator gCaMP3 to efficiently label hMSCs in co-cultures with neonatal rat ventricular myocytes (NRVMs...
