Consecutive organ transplantation in inbred rats: long-term results--Are organs recyclable?

Using 9-12-month-old Lewis rats, our laboratory performed consecutive organ transplantations to assess the technical feasibility and observe the histopathologies of prolonged transplants and implants over a rat's life span. This study includes a total of 688 cases of consecutive syngeneic organ transplantation, including pancreaticoduodenum (PD), en-bloc liver-pancreaticoduodenum-spleen-stomach (LPdSpSt), and spleen bearing ovary or testicle. A 52-month-old consecutively transplanted pancreas showed normal acini and islet cells.
