BARAJAS, M. et al. New therapeutic strategies for type 1 diabetes mellitus. Anales Sis San Navarra [online]. 2008, vol.31, n.3, pp.219-234. ISSN 1137-6627.

The main determinant of the risk of complications from type 1 diabetes mellitus is the total lifetime blood glucose levels. To impact on the health and quality of life of individuals with diabetes, safe and effective methods of achieving and maintaining normoglycemia are needed. Unfortunately, intensive insulin therapy does not achieve normal levels of blood glucose, is difficult to implement for many patients, and limited by the accompanying increased frequency of severe hypoglycemia. Hence, the only way at present to restore permanently normoglycemia without hypoglycemia is to provide the patient with additional beta-cells. This can be achieved by transplanting an intact pancreas, or by transplanting islets. The shortage of functional beta-cells from available donors is one of the major limiting factors for the treatment of diabetes by islet transplantation. Therefore, methods to preserve or even promote regeneration of the beta-cell mass are dearly needed. Significant progress has been made over the last decade in stem cell biology. However, the quest for identification of stem cells has been hampered by the lack of appropriate research tools including assays that allow assess their differentiation potential in vitro and in vivo. Therefore, new techniques are necessary in order to develop new therapeutic strategies based on stem cells for the treatment of diabetes mellitus type 1.
