Washington: Harvard scientists have developed a new bioprinting method that can create intricately patterned 3-D tissue constructs with multiple types of cells and tiny blood vessels. The work is a major step toward creating human tissue constructs It sounds like something from a science fiction plot: so-called three-dimensional printers are being used to fashion prosthetic arms and hands, jaw bones, spinal-cord implants -- and one day perhaps even living human body parts. While the parts printed for Cross-section of multi-cellular bioprinted human liver tissue, stained with hematoxylin & eosin (H&E). (Medical Xpress)—The commercial release of 3D printed liver tissue was announced earlier this week. Organovo is the company behind the release. "It's a very exciting technology, it gives us the benefit of reduced lead times, reduced costs and really increases the flexibility for our engineers to be creative. "Concept to final product used to be a minimum of maybe four weeks, whereas now it can be Organovo has just made their human tissue 3D printing technology available to the public. Dubbed the exVive3D, the 3D printer capable of printing out human liver tissue is now available to researchers that want to test their drugs and chemicals. Aside from the actual organ's cells, printers could also use stem cells, bioengineered materials (like a polymer called alginate that was previously used to make aortic valve tissue) and other substitutes the human a kidney via 3D printing; he even .

3D printing is all the rage right now; people are printing machine parts, statues of cosplayers, model homes, and even prosthetic hands that look like Iron Man’s. But perhaps the most interesting thing that’s currently being printed is human tissue. "This is the foundational step toward creating 3D living tissue," said Jennifer Lewis, senior author of the study, from the Wyss Institute for Biologically Inspired Engineering at Harvard University. Tissue engineers have printed human tissue before The innovative technological development of 3D printing functional human tissues and organs opens up new questions even the more complex organs such as kidneys. The advent of 3D printed organs raises a new and important question for patenting law 3D printers could be used to make artificial human tissue to replace damaged cells, researchers say. The printers use water and lipid molecules to form thousands of connected droplets able to perform cell functions in the bodies, according to a study by .
