The investigators developed a tissue engineering approach that enables rapid deposition of cardiomyocyte microfibers with programmable alignments in 3D geometries. Using this focused rotary jet spinning (FRJS) method, they reproduced tissue scaffolds with contractile cells' helical alignments, resembling complex structures of the musculature and properties of a natural heart. This work represents an important advance towards biofabrication of tissue models for healthy and diseased hearts by manipulating orientation of specific fibers. With the technological advancement over other competing methods, FRJS might provide a pathway towards fabricating other tissues and organs with diverse cell populations.
