Immobilization of primary cultures of insulin-releasing human pancreatic cells.

Transplantation of pancreatic islets isolated from organ donors constitutes a promising alternative treatment for type1 Diabetes, however, it is severely limited by the shortage of organ donors. Ex-vivo islet cell cultures appear as an attractive but still elusive approach for curing type 1 Diabetes. It has recently been shown that, even in the absence of fibrotic overgrowth, several factors, such as insufficient nutrition of the islet core, represent a major barrier for long-term survival of islets grafts.
