A new way to ‘bioprint’ tubular structures that better mimic native vessels and ducts in the body allows fine-tuning of the printed tissues' properties, such as number of layers and ability to transport nutrients. These more complex tissues offer potentially viable replacements for damaged tissue
A team of Brigham and Women's Hospital researchers have developed this new 3-D bioprinting technique. The team explains its new method and results in a paper published in Advanced Materials. Many disorders damage tubular tissues: arteritis, atherosclerosis and thrombosis damage blood vessels, while urothelial tissue can suffer inflammatory lesions and deleterious congenital anomalies. This bioprinting method generates complex tubular structures that mimic those in the human system with higher fidelity than previous techniques.
