INTRODUCTION: Non-union due to large bone loss often causes significant long-term morbidity. We incorporate the use of allogeneic umbilical cord-derived mesenchymal stem cells (UC-MSCs) as part of the diamond concept of regenerative medicine in a case of infected non-union fracture. PRESENTATION OF CASE: We reported a 54-year-old female patient presenting with pain on the right thigh. She was previously diagnosed with a closed fracture of the right femoral shaft and underwent four surgeries before finally being referred to Dr...

PURPOSE: The promotion of spinal fusion using bone autografts is largely mediated by the osteoinductive potential of progenitors/mesenchymal stem cells (MSC) that reside in the marrow spaces of cancellous bone. Iliac crest is the common autograft donor site, but its use presents an increased risk for donor site pain, morbidity and infection. Degenerative bone samples harvested during facetectomy might provide an alternative viable source of osteoinductive autografts. In this study, we conducted an intra-individual comparison of the osteogenic potential of isolated low passage MSC from both sources...

This study was undertaken to determine the mechanism whereby calcitropic hormones and mesenchymal stem cell progeny changes involved in bone repletion, a regenerative bone process that restores the bone lost to calcium deficiency. To initiate depletion, weanling mice with a mixed C57BL/6 (75%) and CD1 (25%) genetic background were fed a calcium-deficient diet (0.01%) for 14 days. For repletion, the mice were re-fed a control diet containing 1.2% calcium for 14 days. Depletion decreased plasma calcium and increased plasma PTH, 1,25(OH)2D, and CTX...

Immunophenotypical characterization of mesenchymal stem cells is fundamental for the design and execution of sound experimental and clinical studies. The scarce availability of species-specific antibodies for canine antigens has hampered the immunophenotypical characterization of canine mesenchymal stem cells (MSC). The aim of this study was to select a panel of species-specific direct antibodies readily useful for canine mesenchymal stem cells characterization. They were isolated from perivisceral and subcutaneous adipose tissue samples collected during regular surgeries from 8 dogs...

Tendon injuries are severe burdens in clinics. The poor tendon healing is related to an ineffective response of resident cells and inadequate vascularization. Thanks to the high proliferation and multi-lineage differentiation capability, bone marrow-derived mesenchymal stem cells (BMSCs) are a promising cell source to support the tendon repair. To date, the association of various growth factors to induce the in vitro tenogenic differentiation of multipotent progenitor cells is poorly investigated. This study aimed to investigate the tenogenic differentiation of rabbit BMSCs by testing the combination of bone morphogenetic proteins (BMP-12 and 14) with transforming growth factor beta (TGF-β) and vascular endothelial growth factor (VEGF) both in 2D and 3D cultures within fibrin-based constructs...

Stem cell research arose from the need to explore new therapeutic possibilities for intractable and lethal diseases. Although musculoskeletal disorders are basically nonlethal, their high prevalence and relative ease of performing clinical trials have facilitated the clinical application of stem cells in this field. However, few reliable clinical studies have been published, despite the plethora of in vitro and preclinical studies in stem cell research for regenerative medicine in the musculoskeletal system...

Mesenchymal stem cells (MSCs) have been used as therapeutic tools not only for their ability to differentiate toward different cells, but also for their unique immunomodulatory properties. However, it is still unknown how MSCs may affect immunity during hepatitis B virus (HBV) infection. This study was designed to explore the effect of bone marrow-derived MSCs (BM-MSCs) on hepatic natural killer (NK) cells in a mouse model of acute HBV infection. Mice were injected with 1 × 10(6) BM-MSCs, which stained with chloromethyl derivatives of fluorescein diacetate fluorescent probe, 24 h before hydrodynamic injection of viral DNA (pHBV1...

Since the discovery of adipose-derived mesenchymal stem cell (ADSC) in more than ten years, a great progress has been made from its basic research to clinical application. Compared with bone marrow mesenchymal stem cells, ADSCs are more abundant in reserve, easier to obtain with fewer injuries and less complications. These cells have multiple differentiation potential and can differentiate into adipocytes, chondrocytes and osteoblasts with the influence of different inducing factors. Early studies of ADSCs mainly focused on the ability of multi-directional differentiation, espe-cially on the regeneration of bone defects and cartilage tissue...

Mesenchymal stem cells (MSC) are promising candidates for adult cell therapies in regenerative medicine. To fully exert their potential, efficient homing and migration towards lesion sites plays an important role. Local transplantation deposits MSC in spatial proximity to the lesion, but often requires invasive procedures. Systemic administration routes are favored, but require the targeted extravasation of the circulating MSC at the site of injury. Transplanted MSC can indeed leave the blood flow and transmigrate through the endothelial barrier, and reach the lesion site...

The topography of biomaterials can significantly influence the osteogenic differentiation of cells. Understanding topographical signal transduction is critical for developing biofunctional surfaces, but the current knowledge is insufficient. Recently, numerous reports have suggested that the unfolded protein response (UPR) and osteogenic differentiation are inter-linked. Therefore, we hypothesize that the UPR pathway may be involved in the topography-induced osteogenesis. In the present study, different surface topographies were fabricated on pure titanium foils and the endoplasmic reticulum (ER) stress and UPR pathway were systematically investigated...

To solve the poor healing of polyethylene terephthalate (PET) artificial ligament in bone tunnel, copper-containing bioactive glass (Cu-BG) nanocoatings on PET artificial ligaments were successfully prepared by pulsed laser deposition (PLD). It was hypothesized that Cu-BG coated PET (Cu-BG/PET) grafts could enhance the in vitro osteogenic and angiogenic differentiation of rat bone marrow mesenchymal stem cells (rBMSCs) and in vivo graft-bone healing after anterior cruciate ligament (ACL) reconstruction in a goat model...

Retinal degenerative diseases, which include age-related macular degeneration, retinitis pigmentosa, diabetic retinopathy and glaucoma, mostly affect the elderly population, and are the most common cause of decreased quality of vision or even blindness. So far, there is no satisfactory treatment protocol to prevent, stop or cure these disorders. A great hope and promise for patients suffering from retinal diseases is represented by stem cell-based therapy which could replace diseased or missing retinal cells, and support regeneration...

Airway epithelial cell injury is a key triggering event to activate allergic airway inflammation, such as asthma. We previously reported that administration of mesenchymal stem cells significantly alleviated allergic inflammation in a mouse model of asthma, and the mmu-miR-21/ACVR2A axis may be involved. However, whether MSCs protect against bronchial epithelial cell injury induced by hypoxia and the underlying mechanism remain unknown. In our study, the human bronchial epithelial cell line BEAS-2B was induced to undergo apoptosis with a hypoxia mimic of CoCl2 damage...

The with-no-lysine kinase (WNK) 4 gene is a causative gene in pseudohypoaldosteronism type II. Although WNKs are widely expressed in the body, neither their metabolic functions nor their extrarenal role is clear. In this study, we found that WNK4 was expressed in mouse adipose tissue and 3T3-L1 adipocytes. In mouse primary preadipocytes and in 3T3-L1 adipocytes, WNK4 was markedly induced in the early phase of adipocyte differentiation. WNK4 expression preceded the expression of key transcriptional factors PPARγ and C/EBPα...

BACKGROUND: While current therapies for osteoporosis focus on reducing bone resorption, the development of therapies to regenerate bone may also be beneficial. Promising anabolic therapy candidates include phytoestrogens, such as daidzein, which effectively induce osteogenesis of adipose-derived stromal cells (ASCs) and bone marrow stromal cells (BMSCs). PURPOSE: To investigate the effects of glyceollins, structural derivatives of daidzein, on osteogenesis of ASCs and BMSCs...

Dental pulp stem cells (DPSCs) are an attractive cell source for use in cell-based therapy, regenerative medicine, and tissue engineering because DPSCs have high cell proliferation ability and multi-differentiation capacity. However, several problems are associated with the collection and preservation of DPSCs for future cell-based therapy. In addition, the isolation of DPSCs for cryopreservation is time-consuming and expensive. In this study, we developed a novel cryopreservation method for dental pulp tissues that can isolate suitable DPSCs after thawing cryopreserved tissue...
