Abstract
The present invention provides a control substrate for controlling a movement direction of animal cells. The control substrate for controlling a movement direction of animal cells has a surface which includes a plurality of grooves, the grooves are formed from a bottom between opposing walls and the opposing walls forming the grooves wherein the walls include a plurality of columnar protrusions. Vertex parts of the columnar protrusion are formed to face between vertex parts of two columnar protrusions formed in the opposing wall and such vertex parts face the same direction.
Claims9
A control substrate which controls a movement direction of animal cells, wherein a surface of the substrate includes a plurality of grooves, the grooves are formed from two opposing walls and a bottom provided between the two opposing walls, and the two opposing walls forming the grooves include continuous columnar protrusions, wherein the columnar protrusions:
- i) have a shape wherein each columnar protrusion has at least one vertex part in a horizontal cross section;
- and
- ii) are provided at positions such that columnar protrusions formed in a wall and columnar protrusions formed in the opposing wall are arranged alternately;
- and wherein a direction of the protrusions is inclined to one direction with respect to a distance direction in which the distance toward the opposing wall is measured.
