3D Bioprinting Solutions

As Russia’s leading bioprinting firm, 3D Bioprinting Solutions aims to 3D print multiple human organs. In fact, they recently were successful in the fabrication of the first known mouse thyroid gland, which they have since implanted into a test subject (yes, another mouse). The company now has an incredibly ambitious timeline in which they seek to develop a 3D printed kidney by 2018. Their machine utilizes stem cells taken from a patient via their fat cells which are then mixed with hydrogels before being printed layer-by-layer. When the hydrogel dissolves, only the cells remain, forming tissue.
