Title:
CELL PATTERNING METHOD AND CELL PATTERNING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/243602
Kind Code:
A1
Abstract:
Provided is a cell patterning method and a cell patterning device which make it possible to control cell proliferation and to easily pattern the shape of a cell population. The cell patterning method comprises: a step for allowing cells to adhere to a cell cultivation substrate 1, on one surface thereof having a first region 11 which blocks ultraviolet light and a second region 12 which allows ultraviolet light to pass through; and a step for irradiating the cell cultivation substrate 1 with ultraviolet light, from the surface opposite to the side that has the cells adhered thereto. Among the cells adhered to the cell cultivation substrate, cells on the second region 12 are removed by the step for irradiating ultraviolet light.
