Abstract
A purified and isolated Sertoli cell and secretory cell hybrid, or an aggregate of these two cells, wherein the secretory cells preferably are pancreatic islet cells and chromaffin cells characterized by being PA1 a) capable of survival in situ after transplantation; PA1 b) able to provide immunoprotection for the hybrid cells when transplanted; and PA1 c) able to provide a mechanism for prolonged viability and cellular functionality of the transplanted hybrid cells wherein the hybrid maintains both the immunoprotection characteristics of the Sertoli cell and the secretory function of the secretory cell.
