Mesenchymal stem cells (MSCs) have attracted attention as a cell source for regenerative medicine. In particular, MSCs have an anti-inflammatory effect by secreting several kinds of bioactive molecules. MSC therapy is now being applied to various gastrointestinal diseases, such as graft-versus-host disease, inflammatory bowel disease, and liver cirrhosis. Therefore, MSC therapy has the potential to be a novel treatment for acute and chronic pancreatitis by suppressing inflammation. Several studies have investigated the effect of MSC therapy on acute and chronic pancreatitis, but the underlying mechanisms remain unknown...

Tumor antigens is at the core of cancer immunotherapy, however, the ideal antigen selection is difficult especially in poorly immunogenic tumors. In this study, we designed a strategy to modify hepatocellular carcinoma (HCC) cells by surface expressing anti-CD3scfv within the tumor site strictly, which depended on the E1A-engineered human umbilical cord mesenchymal stem cells (HUMSC.E1A) delivery system. Subsequently, membrane-bound anti-CD3scfv actived the lymphocytes which lysed HCC cells bypassing the expression of antigens or MHC restriction...

Visual impairment is a common ailment of the current world population, with more exposure to CCD screens and fluorescent lighting, approximately 285 billion people suffer from this deficiency and 13% of those are considered clinically blind. More common causes for visual impairment include age-related macular degeneration (AMD), glaucoma and diabetic retinopathy (Zhu et al. Molecular Medicine Reports, 2015; Kolb et al. 2007; Machalińska et al. Current Eye Research, 34(9),748-760, 2009) among a few. As cases of retinal and optic nerve diseases rise, it is vital to find a treatment, which has led to investigation of the therapeutic potential of various stem cells types (Bull et al...

Mesenchymal stem cells (MSCs) have a large potential in cell therapy for treatment of inflammatory and autoimmune diseases, thanks to their immunomodulatory properties. The encouraging results in animal models have initiated the translation of MSC therapy to clinical trials. In cell therapy protocols with MSCs, administered intravenously, several studies have shown that a small proportion of infused MSCs can traffic to the draining lymph nodes (LNs). This is accompanied with an increase of different types of regulatory immune cells in the LNs, suggesting the importance of migration of MSCs to the LNs in order to contribute to immunomodulatory response...

Mesenchymal stem cells (MSCs) have become one of the most important cell sources for regenerative medicine. However, some mechanisms of MSC-based therapy are still not fully understood. The clinical outcome may be restricted by some MSC-related obstacles such as the low survival rate, differentiation into undesired lineages and malignant transformation. In recent years, with the emergence of nanotechnology, various types of multifunctional nanoparticles (NPs) have been designed, prepared and explored for bio-related applications...

Nature has produced many intriguing and spectacular surfaces at the micro and nanoscales. These small surface decorations act for a singular or, in most cases, a range of functions. The minute landscape found on the lotus leaf is one such example, displaying anti-wetting behaviour and low adhesion with foreign particulate matter. Indeed the lotus leaf has often been considered the 'benchmark' for such properties. One could expect that there are animal counterparts of this self-drying and self-cleaning surface system...

One of the methods employed to improve healing of damaged tissues is the use of cellular based therapies. A number of regenerative medicine based strategies, from in vitro expanded mesenchymal stem cells (MSCs) to "one-step" procedures using bone marrow (BM) in toto (BM aspirate; BMA) or BM concentrate (BMC), have been developed. Recently, orthopedic researchers focused their attention on the clinical therapeutic potential of BMC and BMA for musculoskeletal regeneration. BMA is reported as an excellent source of cells and growth factors...

Mesenchymal stem cells (MSCs) derived from dental and orofacial tissues provide an alternative therapeutic option for craniofacial bone tissue regeneration. However, there is still a need to improve stem cell delivery vehicles to regulate the fate of the encapsulated MSCs for high quality tissue regeneration. Matrix elasticity plays a vital role in MSC fate determination. Here we have prepared various hydrogel formulations based on alginate and gelatin methacryloyl (GelMA) and have encapsulated gingival mesenchymal stem cells (GMSCs) and human bone marrow MSCs (hBMMSCs) within these fabricated hydrogels...

Kidney donation after circulatory death (DCD) is a less than ideal option to meet organ shortages. Hypothermic machine perfusion (HMP) with Belzer solution (BS) improves the viability of DCD kidneys, although the graft clinical course remains critical. Mesenchymal stromal cells (MSC) promote tissue repair by releasing extracellular vesicles (EV). We evaluated whether delivering MSC-/MSC-derived EV during HMP protects rat DCD kidneys from ischaemic injury and investigated the underlying pathogenic mechanisms...

The need of synthetic bone grafts that recreate from macro to nanoscale level the biochemical and biophysical cues of bone extracellular matrix (ECM) has been a major driving force for the development of new generation of biomaterials. In this study, synthetic bone substitutes have been synthesized via biomimetic mineralization of a recombinant collagen type I derived peptide (RCP), enriched in tri-amino acid sequence arginine-glycine-aspartate (RGD). 3D isotropic porous scaffolds of three different compositions are developed by freeze-drying: non-mineralized (RCP, as a control), mineralized (Ap/RCP) and mineralized scaffolds in presence of magnesium (MgAp/RCP) that closely imitate bone composition...

In order to induce an efficient bone formation with human bone marrow mesenchymal stromal cells (hBMSC) associated to a scaffold, it is crucial to determine the key points of the hBMSC action after in vivo transplantation as well as the appropriate features of a scaffold. To this aim we compared the hBMSC behavior when grafted onto two biomaterials allowing different bone potential in vivo. The cancellous devitalized Tutoplast®-processed bone (TPB) and the synthetic hydroxyapatite/β-tricalcium-phosphate (HA/βTCP) which give at 6 weeks 100% and 50% of bone formation respectively...

Mesenchymal stem cells (MSC) are ideal materials for stem cell-based therapy. As MSCs reside in hypoxic microenvironments (low oxygen tension of 1% to 7%), several studies have focused on the beneficial effects of hypoxic preconditioning on MSC survival; however, the mechanisms underlying such effects remain unclear. This study aimed to uncover the potential mechanism involving 78-kDa glucose-regulated protein (GRP78) to explain the enhanced MSC bioactivity and survival in hindlimb ischemia. Under hypoxia (2% O₂), the expression of GRP78 was significantly increased via hypoxia-inducible factor (HIF)-1α...

OBJECTIVE: We previously reported that low intensity pulsed ultrasound (LIPUS) promotes marrow stromal cell (MSC) osteogenesis and suppresses the LPS-induced inflammatory response in osteoblasts. Here, we examined the effects of LIPUS on human periodontal ligament-derived stem cells (hPDLSCs) in chronic inflammatory bone disease, such as periodontitis. MATERIALS AND METHODS: hPDLSCs were collected from 3 healthy third molars. hPDLSCs were induced to differentiate by either recombinant BMP2 or BMP9 with or without daily LIPUS treatment (20 min/d)...

The marine origin polysaccharide fucoidan combines multiple biological activities. As demonstrated by various studies in vitro and in vivo, fucoidans show anti-viral, anti-tumor, anti-oxidant, anti-inflammatory and anti-coagulant properties, although the detailed molecular action remains to be elucidated. The aim of the present study is to assess the impact of crude fucoidan extracts, on the formation of vascular structures in co-culture models relevant for bone vascularization during bone repair and for vascularization processes in osteosarcoma...

This study was performed to investigate the safety and efficacy of the intra-articular infusion of ex vivo expanded autologous bone marrow-derived mesenchymal stem cells (BM-MSC) to a cohort of patients with articular cartilage defects in the hip. The above rationale is sustained by the notion that MSCs express a chondrocyte differential potential and produce extracellular matrix molecules as well as regulatory signals, that may well contribute to cure the function of the damaged hip joint. A cohort of 10 patients with functional and radiological evidences of hip osteoarthritis, either in one or both legs, was included in the study...

While transplantation of Schwann cells facilitates axon regeneration, remyelination and repair after peripheral nerve injury clinical use is limited by cell bioavailability. We posit that such limitation in cell access can be overcome by the use of autologous bone-marrow derived mesenchymal stem cells (MSCs). As MSCs can transdifferentiate to Schwann cell-phenotypes and accelerate nerve regeneration we undertook proteomic evaluation of the cells to uncover the protein contents that affects Schwann cell formulation...
