Specialized 3D printer allows production of human tissues

Scientists have recently developed a novel method to 3D print cells to produce human tissue. This revolutionary 3D printing technique means that patients with ruptured spinal discs, ligament or tendon damage can have replacements printed and implanted, improving patient recovery and time spent in hospital. The 3D printing technique is the product of a team of Biomedical Engineers at the University of Utah (UT, USA). The process starts with harvesting stem cells from the patient's own body fat and then printing them on a layer of hydrogel in a microfluidic device. These cells are then left to grow in vitro...
