    Abstract : Islet transplantation has found its niche in diabetes treatment. It has contributed to a better quality of life and better glycemic control of patients with diabetes suffering from severe hypoglycemia that are not eligible for vascularized pancreas transplantation. Islet isolation is a technically challenging procedure. READ MORE

    Abstract : Currently, the transplantation of islets of Langerhans is a viable means to maintain control of blood sugar levels and reduce the risk of hypoglycemia in defined populations with brittle type I diabetes mellitus or those requiring pancreatectomy. However, the process of islet isolation is highly variable and not all isolations result in islet numbers or quality suitable for transplantation. READ MORE

  3. 3. Technical challenges in human islet isolation

    Author : Magnus Ståhle; Olle Korsgren; Andrew Friberg; Federico Bertuzzi; Uppsala universitet; []

    Abstract : Transplantation of islets of Langerhans is an effective treatment option for patients with brittle type 1 diabetes mellitus. This treatment restores glucose control and also reduces hypoglycemia. Unfortunately, the outcome from islet isolations is variable, and many preparations do not yield sufficient islet number or islet quality. READ MORE

  4. 4. Implantation-Site Dependent Differences in Engraftment and Function of Transplanted Pancreatic Islets

    Abstract : Transplanting pancreatic islets into the liver through the portal vein is currently the most common procedure in clinical islet transplantations for treating patients with brittle type 1 diabetes. However, most islet grafts fail within a 5-year period necessitating retransplantation. READ MORE

  5. 5. Human Embryonic Stem Cells - Constitutive Gene Expression and Differentiation Towards Definitive Endoderm and Posterior Foregut Endoderm

    Abstract : Abstract More than 300 million people are suffering from diabetes worldwide and the numbers of diabetic patients are increasing. Today´s treatments mainly rely on daily insulin injections. This help people to control blood glucose levels but still many patients suffer from the many complications associated with diabetes.
