Abstract
It is an object of this invention to provide a cell culture vessel which has a simple and convenient structure, can prevent the injury on the cells at the time of peeling, and accelerates the transportation of nutrients and discharge of waste materials. In order to solve the problem mentioned above, the cell culture vessel of this invention has protrusions having a corresponding diameter not smaller than 10 nm and not greater than 10 μm and a height not smaller than 10 nm and not greater than 1 mm on the surface of the cell culture vessel. The protrusions make the culture fluid permeate into the under part of the cells, accelerate the supply of nutrients and discharge of waste materials, and makes the contact between the cells and the vessel as a point-contact and thereby prevents the cells from the injury which the cells undergo at the time of peeling.
