Abstract
The invention provides a microfluidic device comprising at least one cell culture chamber, the at least one cell culture chamber being connected to at least two openings, the device being configured to supply at least one physiologically active substance from at least one of the openings to the at least one cell culture chamber in such a manner as to form a concentration gradient or concentration gradients in the at least one cell culture chamber when cells and a hydrogel are introduced into the at least one cell culture chamber to culture the cells in a 3D-gel medium.
