Method for producing a three-dimensional biological structure and said structure thus obtained

Abstract

The invention relates to a mctliod for bio-printing a thrcc-dimensional biological structure containing liv ing cells having at least two different materials for the bio-printing. Said method is distinguished by the fact that, in at least one step, one of the materials for printing is applied or introduced by printing droplets (drop-on-dentand) printing. In particular, this method is suitable for printing tissue structures. including those which have supply structures. Such structures are in particular cardiac structures, liver structures, kidney structures, alveolar structures, skin struchircs or neural structuies. The invention further relates to a biological three-dimensional structure thus obtainable. Finally, the invention relates to the use of a three-dimensional structure according to the invention as a tissue model, in particular as a model for tissue genesis, for example suitable for testing therapy forms or for the stratification of a therapy or for testing or identifying active substance candidates.
