According to statistics, every day about 18 people die while waiting for organ transplants , and often the main obstacle to successful transplantation are not the most complicated surgical techniques, and the lack of suitable material - organ donation. In the future solution could be the creation of artificial organs bulk printing method, and that day may come sooner than you think. Organovo company, whose headquarters is located in San Diego, spoke about its achievements in the field of bulk printing human tissue. Researchers have managed to find a way to create tissue vascular system by which living cells are delivered all the necessary nutrients and oxygen. Without it, the tissue begins to die before the completion of the direct printing process.
Experts Organovo printed liver tissue thickness of 500 microns (5 sheets), and a fully functional state of the organ was maintained for 40 days. However, printing hepatocytes - cells constituting up to 80% by weight of the liver - insufficient to recreate the full authority required as fibroblasts and endothelial cells. Combining the required components, Organovo can create thick fabric with good cell viability. It is expected that the technology will be suitable for such applications in late 2014.
