Abstract

Official abstract text for this publication.

A device for simulating a function of a tissue includes a first structure, a second structure, and a membrane. The first structure defines a first chamber. The first chamber includes a matrix disposed therein and an opened region. The second structure defines a second chamber. The membrane is located at an interface region between the first chamber and the second chamber. The membrane includes a first side facing toward the first chamber and a second side facing toward the second chamber. The membrane separates the first chamber from the second chamber.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of seeding cells, comprising: (a) providing a microfluidic device comprising a first chamber, the first chamber including a three-dimensional gel matrix disposed therein, and a second chamber, said second chamber separated from the first chamber by a membrane, the gel matrix positioned under a removable cover that comprises a fluidic chamber, wherein said fluidic chamber of said removable cover substantially aligns with all of an open top region of the first chamber; (b) removing the removable cover thereby exposing the gel matrix; and (c) seeding cells within the gel matrix. 2. The method of claim 1 , wherein the gel matrix has a patterned surface. 3. The method of claim 1 , wherein the membrane includes endothelial cells. 4. The method of claim 1 , wherein the second chamber includes fluidics configured to supply the cells with culture fluid. 5. The method of claim 1 , further comprising (d) culturing the cells submerged in culture fluid. 6. The method of claim 5 , further comprising (e) culturing the cells in air without culture media. 7. The method of claim 1 , wherein said cells are intestinal cells.
