Abstract

In this video, we describe a procedure to infuse pancreatic islet cells into the hepatic portal vein, followed by application of gel foam to successfully prevent bleeding. Postoperative bleeding is a common cause of high mortality during islet transplantation.
Protocol
1. Islet transplantation Induce and maintain the mouse under general anesthesia with 2% isoflurane. Check for the lack of pedal reflexes to ensure proper anesthetization of the animal. Shave and remove the fur in the abdomen area of the mouse. Administer a single pre-operative dose of Buprenorphine (0.1 mg/kg i.p.). Disinfect the surgical area with three alternating wipes of 2% iodine and 75% alcohol. Perform a laparotomy with micro scissors to generate…
