Abstract
A system () for forming and maintaining a biological tissue by which a biological tissue can be artificially formed by culturing cells, which comprises a pulse pump (), a circulation pathway () having such a circuit structure as allowing a liquid cell culture medium discharged from the pulse pump () to return into the pulse pump (), and a cell culture section (A) and a gas exchange section (B) provided along the circulation pathway (). The cell culture section (A) holds a cell holder (H) in such a manner to form a first channel wherein the liquid cell culture medium flowing in the circulation pathway () passes through the cell holder (H) and returns into the circulation pathway () and a second channel wherein the liquid cell culture medium flowing in the circulation pathway () passes outside the cell holder (H) and returns into the circulation pathway thereby bringing about a difference in pressure between the liquid cell culture medium passing through the respective channels.
