Abstract: The invention relates to developments in the treatment of diabetes in mammals. Particularly it relates to a method of preparing a xenotransplantable porcine islet preparation capable upon xenotransplantation of producing porcine insulin in an appropriate recipient mammal, the method including or comprising the steps of: (I) harvesting the pancreas of piglets at or near full term gestation, and (ii) extracting pancreatic ? islet cells from the harvested pancreas wherein the islets (at least at some stage in the performance of the method) are exposed to nicotinamide. Further, the invention relates to a method of encapsulation of a xenotransplantable porcine islet preparation, and transplantation of such a preparation, or a capsule containing such a preparation, into an appropriate recipient mammal.

Abstract: The invention relates to a method of preparing a xenotransplantable porcine islet preparation capable upon xeno-transplantation of producing porcine insulin in an appropriate recipient mammal, the method including or comprising: (i) harvesting the pancreas of piglets at or near full term gestation, and (ii) extracting islets from a culture of the harvested pancreas using a suitable collagenase, (iii) the culture of the harvested pancreas being a) of mechanically reduced harvested pancreas, and b) a supportive mammalian albumin substantially free of non-human microbiological agents, wherein (at least some stage in the method) the islets are associated with Sertoli cells.
