Researchers at the University of Alabama at Birmingham (UAB) have developed a bioprinter that can speed computer-controlled human tissue creation.

The tissue by the bioprinter forms out of pre-grown spheroids of human induced-pluripotent stem cells that contain 200,000 cells per spheroid.

The first commercial bioprinter builds tissue one spheroid at a time. The UAB approach could increase the efficiency of that system by as much as a hundredfold.

The new bioprinter picks up multiple spheroids at the same time and places them simultaneously on a matrix of pins.

Said UAB researcher Jianyi "Jay" Zhang, "Having the ability to build larger, more clinically relevant tissues in a shorter length of time using this method would be very beneficial for various fields of medicine and clinical research."
