PANCREATIC ISLET TRANSPLANTATION IN CAPSULES OF CELLULAR IMMUNOISOLATION: PRELIMINARY RESULTS

There have been great developments in pancreas and pancreatic islet cell transplantion in the last few years. The isolation of the islet cells in capsules with semi-permeable membranes may become ideal means of treating diabetes, and the use of immunossuppression could be avoided. The ideal material for the confection of the capsules has remained a dream. A new material derived from natural latex was implanted in the subcutaneous tissue of normal and diabetic rats to study the biocompatibility and the vascular neoformation. After 21 days, an analysis of the implant showed intense vascular neoformation on the membrane-tissue interface and little fibrotic tissue. The inicial results show great promise for utilization of this material in capsules for the isolation of cells.
