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