According to CNBC, Cyfuse Biomedical a Tokyo-based start-up in regenerative medicine is developing the ability to 3D bioprint organs as needed using a patient's own cells. Reportedly, scientists were already able to print blood vessels of far greater strength than those found in the human body.

Bioprinting works like this: Scientists harvest human cells from biopsies or stem cells, then allow them to multiply in a petri dish. The resulting mixture, a sort of biological ink, is fed into a 3-D printer that is programmed to arrange different cell types and materials into a three-dimensional shape. Doctors hope that when placed into the body, these 3-D printed cells will integrate with existing tissue.
While breakthroughs in central nervous system and cardiac treatments remain in the future for now, Cyfuse's Regenova bioprinter is attracting attention from the scientific community. The bioprinter is a robotic system that facilitates the fabrication of 3-D cellular structures by placing cellular spheroids in fine needle arrays according to predesigned 3-D data. Among Cyfuse's goals: to treat spinal injuries and heart failure.
