Device and method for growing and analyzing cells
A device and method for analyzing cells includes a housing with a chamber, a barrier supported by a frame disposed within the chamber, and a plate arranged at a bottom surface of the housing interior of the chamber. The plate is adapted to receive and sustain cells and the barrier separates the plate into at least two contiguous separate areas. In some embodiments, a thin rubber strip is arranged at the bottom edge of the barrier, which facilitates control of the area in which each cell type is grown, the size of the gap between the cells, and helps prevents over growth of the two cell types on to each other.
1. A method, comprising:
a) providing a removable barrier comprising a strip formed from a soft material of a predetermined thickness arranged on a bottom edge of a barrier,
b) placing the removable barrier on a plate such that the strip contacts the plate thereby dividing the plate into at least two separate areas;
c) forming cells on the plate in the at least two separate areas on opposite sides of the barrier;
d) removing the barrier after forming the cells; and
e) detecting at least one parameter of the cells on the plate after removing the barrier.
2. The method of claim 1 , wherein the at least one parameter includes an electrical activity of the cells.
3. The method of claim 1 , further comprising forcing the barrier against the plate at a predetermined pressure.
4. The method of claim 3 , wherein the pressure is sufficient to prevent cell growth across the barrier without leaving an indentation on the plate.
5. The method of claim 1 wherein the soft material is rubber.
