Abstract

The present invention relates to a three-dimensional scaffold for tissue regeneration, using a variety of materials including a water-soluble material such as collagen, and to a method for producing same. More particularly, the present invention relates to a method for effectively producing a three-dimensional scaffold for tissue regeneration by means of a cryogenic method for producing a cell culture scaffold for tissue regeneration.
