Abstract

Official abstract text for this publication.

Described herein are methods for providing an in vitro intestinal model system, e.g., using primary cells instead of cell lines and/or cancerous cells.

First claim

Opening claim text (preview).

What is claimed herein is: 1. A method of providing an in vitro intestinal model system, the method comprising: a) providing i) intestinal endothelial cells, ii) an intestinal enteroid or colonoid comprising primary intestinal epithelial cells, iii) a microfluidic culture device, the device comprising a porous membrane having a first surface and a second surface, said membrane in fluidic communication with a microchannel, said microchannel in fluidic communication with a source of fluid; b) disrupting said intestinal enteroid or colonoid comprising primary intestinal epithelial cells into enteroid or colonoid fragments; c) seeding said first surface of said porous membrane with said enteroid or colonoid fragments so as to create seeded primary intestinal epithelial cells; d) seeding said second surface of said porous membrane with said intestinal endothelial cells; e) expanding said seeded primary intestinal epithelial cells in a first media comprising Wnt-3A so as to create a monolayer of the intestinal epithelial cells; f) replacing said first media comprising Wnt-3A and culturing said intestinal epithelial cells with a second media lacking Wnt-3A; and g) culturing said intestinal endothelial cells in a third media comprising Wnt-3A. 2. The method of claim 1 , wherein said first media further comprises Noggin. 3. The method of claim 1 , wherein said first media further comprises a ROCK inhibitor. 4. The method of claim 1 , wherein said first media further comprises R-spondin.
