Renal Organotypic Culture on Chicken CAM: A Technique for Transplantation of Murine Kidney Explants on Chicken CAM to Induce Formation of Renal Vascular Architecture

Abstract

This video describes a method for studying organ development using an improved xenotransplantation setup on chorioallantoic membrane (CAM) from avian embryos. This method allows for the development of fully vascularized cultured embryonic organs and organoids.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board 1. Fabrication of Minireservoirs for Cultivation of Mouse Embryonic Kidneys and Renal Organoids on Chicken CAM and Setting Up Xenotransplantation Experiments Use transwell cell culture inserts designed for 6-well or 12-well plates. NOTE: Depending on the particular experiment, large or small minirese…
