Decellularized Porcine Esophageal Scaffold Preparation: A Technique to Generate Acellular Scaffold from a Pig Esophagus

Abstract

Source: Green, N. H. et al. Production, characterization and potential uses of a 3D tissue-engineered human esophageal mucosal model. J. Vis. Exp. (2015)

In this video, we demonstrate the preparation of a decellularized pig esophagus scaffold, with its biochemical architecture and composition preserved, for tissue engineering applications.

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 Decellularized Esophageal Scaffold

1. Obtain intact porcine esophagi at an abattoir from freshly slaughtered Landrace pigs that are used for food production. One single esophagus will provide sufficient scaffolds for approximately 30 separate constructs.
   NOTE: Due to the extensive and time-consuming sterilization protocol required, it is normally worth obtaining and processing a minimum of 10 esophagi at one time.
2. Immedia....
