Grafting Pancreatic Islets: A Method to Implant Pancreatic Islets into the Anterior Chamber of the Mouse Eye for In Vivo Imaging

Samenvatting

This video describes the protocol for grafting human pancreatic islets into the anterior chamber of the mouse’s eye to monitor revascularization of human islet grafts in vivo. It also helps to understand the contribution of recipient versus donor cells in promoting the encapsulation and vascularization of the graft.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the jove veterinary review board

1. Preparation of transplantation equipment and surgery table

NOTE: All surgical tools should be autoclaved, and the surgery table and instruments disinfected with 70% alcohol.

1. Connect a stereotaxic head holder to anesthesia via a nose mask and turn on the heating pad.
2. Connect a gastight Hamilton syringe to polyethylene tubing and a blunt end eye cannula.
   NOTE: It is recommended to fill all pa....
