Though cell transplantation is becoming an attractive therapeutic method, uncontrolled cell proliferation or overexpression of cellular functions could cause adverse effects. These unfavorable outcomes could be avoided by regulating the proliferation or functioning of transplanted cells. In this study, we used a combination of the herpes simplex virus thymidine kinase (HSVtk) gene, a suicide gene, and ganciclovir (GCV) to control the proliferation and functioning of insulin-secreting cells after transplantation in diabetic mice...

Generation of new β cells is an important approach in the treatment of type 1 diabetes mellitus (type 1 DM). Adipose tissue-derived stem cells (ADSCs) might be one of the best sources for cell replacement therapy for diabetes. Therefore, this work aimed to test the possible role of transplanted insulin-producing cells (IPCs) differentiated from ADSCs in treatment of streptozotocin (STZ) induced type I DM in rats. Type 1 DM was induced by single intra peritoneal injection with STZ (50 mg/kg BW). Half of the diabetic rats were left without treatment and the other half were injected with differentiated IPCs directly into the pancreas...

Cell therapy has become a momentum-gathering treatment strategy for a variety of diseases, including cancer, diabetes, hemophilia, and cardiomyopathy. However, clinical applications of conventional cell therapies have often been compromised by rapid decline in viability and function of the transplanted cells due to host recognition and subsequent foreign body rejection. Along this line, cell engineering technologies such as cell encapsulation within microcapsules and immobilization in porous scaffolds have been implemented to address the immunosuppression concerns...

BACKGROUND Vascular calcification (VC) progresses substantially even after kidney transplantation, and is a predictor of morbidity and mortality. However, the effect of cyclosporin A (CsA) on VC has not been reported in diabetic kidney transplant patients. In this study, we evaluated the effect of CsA on the VC of mouse vascular smooth muscle cells (VSMCs) under high glucose (HG). MATERIAL AND METHODS To demonstrate the effect of CsA (1.0 µmol/L) and HG (30 mM) in the induction of the VC of the VSMCs, we determined alkaline phosphatase (ALP) activity, microscopic morphology of calcification, the expressions of the calcification and inflammation-related genes, and the intracellular calcium concentrations in VSMCs...

In sepsis, trauma and major surgery, where an explicit physiological insult leads to a significant systemic inflammatory response, the acute evolution of biomarkers have been delineated. In these settings, Interleukin (IL) -6 and TNF-α are often the first pro-inflammatory markers to rise, stimulating production of acute phase proteins followed by peaks in anti-inflammatory markers. Patients undergoing SPKT as a result of diabetic complications already have an inflammatory phenotype as a result of uraemia and glycaemia...

The prevalence of chronic heart failure (CHF) is steadily increasing. Both sexes are affected, with significant differences in etiology, epidemiology and clinical presentation, prognosis, comorbidities, and response to treatment. Women tend to develop CHF at a more advanced age, present more often with HF with preserved ejection fraction, are more symptomatic, and have a worse quality of life than men, but also a better prognosis. In women, CHF has more frequently a non-ischemic etiology, and arterial hypertension and diabetes mellitus are leading comorbidities...

Mesenchymal stem cell (MSC) transplantation is a novel treatment for diabetes mellitus, especially type 1 diabetes. Many recent publications have demonstrated the efficacy of MSC transplantation on reducing blood glucose and increasing insulin production in both preclinical and clinical trials. However, the investigation of grafted cell doses has been lacking. Therefore, this study aimed to evaluate the different doses of MSCs on treatment of type 1 diabetes in mouse models. MSCs were isolated and expanded from human adipose tissue...

Post-liver transplantation diabetes mellitus (PLTDM) develops in up to 30% of liver transplant recipients and is associated with increased risk of mortality and multiple morbid outcomes. PLTDM is a multicausal disorder, but the main risk factor is the use of immunosuppressive agents of the calcineurin inhibitor (CNI) family (tacrolimus and cyclosporine). Additional factors, such as pre-transplant overweight, nonalcoholic steatohepatitis and hepatitis C virus infection, may further increase risk of developing PLTDM...

Tissue engineering of insulin-secreting cells using alternatives to islet transplantation has been fueled by the development of available materials and fabrication techniques. We have established a cell coating technique that enables the cell surface to be coated with extracellular matrix based on the concept of a layer-by-layer (LbL) assembly. The present study evaluated whether this technique is beneficial for fabricating pancreatic β-cell spheroids using a mouse β-cell line. The well-structured and dense spheroids could immediately be constructed by the LbL-coated cells...

BACKGROUND: Pancreas transplantation is the only curative treatment option for patients with juvenile diabetes. Organ shortage and restrictive allocation criteria are the main reasons for increasing waitlists leading to severe morbidity and mortality. We designed a study to increase the donor pool with extended donor criteria (EDC) organs (donor age 50-60 years or BMI 30-34kg/m). METHODS: Utilization of EDC organs required the implementation of a new allocation system within Eurotransplant...

Deficient insulin secretion caused by immaturity is the predominant disadvantage of neonatal porcine islets (NPIs) when they serve as a source for islet xenotransplantation. We hypothesize that the transplantation of NPIs with a combination of mesenchymal stem cells (MSCs) can accelerate NPI maturation and improve the engraftment and function of NPIs. After indirect coculturing with monkey MSCs over 21 d, insulin secretion and the expression of regulatory genes relevant to development were assessed in NPIs...
