First Claim
Patent Images
1. A cell culture or tissue engineering support comprising:
- (i) a porous matrix based on a collagen sponge which defines first pores,wherein said collagen comprises a mixture of at least one collagen which undergoes slow bioresorption in vivo and at least one collagen which undergoes rapid bioresorption in vivo; and
(ii) a porous three-dimensional knit which defines second pores;
wherein said porous matrix fills said three-dimensional knit and all the first and second pores are interconnected with one another.
