Abstract

A cell culture device comprising a microscale chamber dimensioned to maintain a cell under conditions that give rise to a value for at least one pharmacokinetic parameter in vitro that is comparable to a value for the same at least one pharmacokinetic parameter obtained with respect to the same type of cell in vivo, wherein the microscale chamber is configured for flow of culture medium, and wherein the at least one pharmacokinetic parameter is selected from tissue size ratio, tissue to blood volume ratio, drug residence time, flow rate, circulatory transit time, liquid residence time, and liquid to cell ratio.

First claim

What is claimed is:

1. A cell culture device comprising a microscale chamber dimensioned to maintain a cell under conditions that give rise to a value for at least one pharmacokinetic parameter in vitro that is comparable to a value for the same at least one pharmacokinetic parameter obtained with respect to the same type of cell in vivo, wherein the microscale chamber is configured for flow of culture medium, and wherein the at least one pharmacokinetic parameter is selected from tissue size ratio, tissue to blood volume ratio, drug residence time, flow rate, circulatory transit time, liquid residence time, and liquid to cell ratio.

2. The cell culture device of claim 1 , wherein the at least one pharmacokinetic parameter is tissue size ratio.

3. The cell culture device of claim 1 , wherein the at least one pharmacokinetic parameter is tissue to blood volume ratio.

4. The cell culture device of claim 1 , wherein the at least one pharmacokinetic parameter is drug residence time.

5. The cell culture device of claim 1 , wherein the at least one pharmacokinetic parameter is flow rate.

6. The cell culture device of claim 1 , wherein the at least one pharmacokinetic parameter is circulatory transit time.

7. The cell culture device of claim 1 , wherein the at least one pharmacokinetic parameter is liquid residence time.

8. The cell culture device of claim 1 , wherein the at least one pharmacokinetic parameter is liquid to cell ratio.

9. The cell culture device of claim 1 , wherein the microscale chamber comprises a first inlet and a first outlet for flow of culture medium.

10. A method of evaluating the effect of a material on a cell, comprising:
introducing the cell into the microscale chamber of a cell culture device of claim 1 ;
culturing the cell in the microscale chamber while flowing culture medium through the chamber;
contacting the cultured cell with the material; and
evaluating the effect of the material on the cultured cell.

11. A cell culture device comprising a microscale chamber containing a cell, wherein the microscale chamber is dimensioned to maintain the cell under conditions that dive rise to a value for at least one pharmacokinetic parameter in vitro that is comparable to a value for the same at least one pharmacokinetic parameter obtained with respect to the same type of cell in vivo, wherein the microscale chamber is configured for flow of culture medium, wherein the at least one pharmacokinetic parameter is selected from tissue size ratio, tissue to blood volume ratio, drug residence time, flow rate, circulatory transit time, liquid residence time, and liquid to cell ratio.

12. A cell culture device comprising a microscale chamber containing a cell, wherein the microscale chamber is dimensioned to maintain the cell under conditions that give rise to a value for at least one pharmacokinetic parameter in vitro that is comparable to a value for the same at least one pharmacokinetic parameter obtained with respect to the same type of cell in vivo, wherein the microscale chamber is configured for flow of culture medium, wherein the at least one pharmacokinetic parameter is metabolism by cells, and wherein the metabolism by cells is achieved by at least one of tissue size ratio, tissue to blood volume ratio, drug residence time, flow rate, circulatory transit time, liquid residence time, and liquid to cell ratio.
