Abstract
It is an object of the present invention to provide a Type I-Type IV collagen hybrid gel, which maintains characteristics of a Type IV collagen and is superior in gel strength. It is the Type I-Type IV collagen hybrid gel obtained by mixing 100 to 500 parts by mass of the Type I collagen having fibrosis ability, relative to 100 parts by mass of the Type IV collagen having gelling ability. A three-dimensional structure is formed, where a membrane-like substance by the Type IV collagen is formed onto a fibrous substance by the Type I collagen, so as to be able to provide cell culture environment approximate to a basement membrane of a living body.
