High-Resolution, 3D Cell-Printing of Living Tissues

摘要

Printing high-resolution living tissues is difficult, as the cells often move within printed structures, and can collapse on themselves. A method of 3D-printing laboratory-grown cells to form living structures was developed that produces tissues in self-contained cells that support the structures to keep their shape. The approach could be used in regenerative medicine, enabling the production of complex tissues and cartilage that would potentially support, repair, or augment diseased and damaged areas of the body.
