Composite scaffolds and methods using same for generating complex tissue grafts

摘要

A composite scaffold for engineering a heterogeneous tissue is provided. The composite scaffold includes: (a) a first scaffold being capable of supporting formation of a first tissue type thereupon; and (b) a second scaffold being capable of supporting formation of a second tissue type thereupon; wherein the first scaffold and the second scaffold are arranged with respect to each other such that when the first scaffold supports the first tissue type and the second scaffold supports the second tissue type, a distance between any cell of the second tissue type and the first tissue type does not exceed 200 μm.
