22 Beta Cell Replacement Therapy

Cell therapy: replacement.

Not long ago, the ability of the brain to restore function through regeneration of neural elements was thought to be nonexistent. It is now known that not only does some regenerative capacity exist, but implanted cells can integrate into the host brain, survive, and reverse neurological deficits. Neural stem cells, fetal transplants, immortalized cell lines, and bone marrow stromal cells show p...

Beta-cell replacement for type I diabetes.

The ability to achieve insulin independence with either solid-organ pancreas or islet transplantation has increased the number of patients seeking beta-cell replacement as an alternative to insulin therapy. Despite dramatic improvements in the ability to achieve insulin independence following solid-organ pancreas transplantation, the secondary complications of long-standing diabetes are frequen...

Toward beta cell replacement for diabetes.

The discovery of insulin more than 90 years ago introduced a life-saving treatment for patients with type 1 diabetes, and since then, significant progress has been made in clinical care for all forms of diabetes. However, no method of insulin delivery matches the ability of the human pancreas to reliably and automatically maintain glucose levels within a tight range. Transplantation of human is...

Insulin therapy for type 2 diabetes: rescue, augmentation, and replacement of beta-cell function.

Type 2 diabetes is characterized by progressive beta-cell failure. Indications for exogenous insulin therapy in patients with this condition include acute illness or surgery, pregnancy, glucose toxicity, contraindications to or failure to achieve goals with oral antidiabetic medications, and a need for flexible therapy. Augmentation therapy with basal insulin is useful if some beta-cell functio...
