Method for assaying cell movement
The present invention relates to the field of assays of cell movement. In particular, the present invention provides methods for assaying cell movement where inserts are used to confine cells to a defined area in a well of a multiwell plate and movement from the defined area is assayed.
1. A method for assaying cell movement comprising:
a) providing:
i) a multiwell plate comprising a bottom surface;
ii) an elongated member configured for use with said multiwell plate, said elongated member comprising a surface that contacts the bottom surface of said well and has an opening therein that exposes said bottom surface of said well to constrain cells to a discrete location within said well when said insert is inserted into said well; and
iii) cells
b) inserting said elongated member into at least one well of said multiwell plate, wherein said elongated member contacts said bottom surface of said well to define said discrete location on said bottom surface of said at least one well;
c) seeding said cells in said at least one well in said multiwell plate;
d) incubating said cells with said elongated member in said at least one well;
e) removing said elongated member after said cells have attached to said bottom surface of said well, wherein said seeded cells are confined to said discrete location defined by said elongated member
f) culturing said cells;
g) assaying said cells for movement from said discrete location.
2. The method of claim 1 , wherein said assaying is selected from the group consisting of colorimetric, fluorimetric, optical density, liquid crystal and light scattering assays.
3. The method of claim 2 , wherein said assays are read by a plate reader.
4. The method of claim 1 , wherein said multiwell plate is selected from the group consisting of 6, 12, 24, 36, 96, 384, or 1536 well plates.
5. The method of claim 1 , wherein said at least one well is configured to orient mesogens.
6. The method of claim 1 , further comprising the step of contacting said cells with a test compound suspected of promoting or inhibiting movement of said cells.
7. The method of claim 1 , wherein said discrete location is circular.
8. The method of claim 1 , wherein said wells are partially masked.
