Lab-made heart represents \'moonshot\' for 3D printing
The printed heart project aims to provide natural organ replacement for patients within ten years.
But researchers in charge of \"Moon shooting\" also believe that 3D
Printing technology must take advantage of itself
The power of Organizational biology to do the work.
Concept of 3D-
The printed heart grown by the patient\'s own fat stem cells comes from Stuart Williams, executive and scientific director of the Institute for Cardiovascular Innovation in Louville, Kentucky.
His lab has begun to develop the next generation of customized products.
Built in 3D printer designed to print out all parts of a complete heart, heart muscles, blood vessels, heart valves and electrical tissue.
\"We can print the individual parts of the heart, but we are building the next step --
\"Build the heart\'s generation printer from bottom to top,\" Williams said . \".
The heart represents one of the most ambitious goals of researchers working to create 3D
Printing organs in the field of regenerative medicine.
The ability of 3D printing to construct human tissue by placing living cells layer by layer has allowed researchers to create small organs by using stem cells extracted from fat, such as liver and kidney or bone marrow as the source material. [
7 Cool uses of 3D printing in medicine]
Williams and the Cardiovascular Innovation Institute first used 3D printing technology to create parts of the heart that they thought were \"Biomedical.
This piecemeal approach ultimately allows researchers to print and piece together a fully functional heart within a week.
\"I took a step back and looked at my colleague and said, \'Why don\'t we build it like a big plane?
Williams told life science.
\"Divide the organs into separate components, find out the best way to make them, and then put them together.
\"But construction is complete
The size of the organ also requires researchers to print the way the human tissue is, including a complex network of tiny blood vessels that keep the organ healthy.
Williams believes that 3D printing is the ideal way to make smaller blood vessels, and he and his colleagues have built large blood vessels for surgical transplants using methods other than 3D printing.
Nevertheless, 3D printers can only do so much bioengineering when working at the smallest scale.
Williams explained that the best printer might print only a structure of millimeter size, while the width of the smallest vessel could be only a few micrometers, of which 1mm equals 1,000 micrometers.
That\'s why 3D printing may only allow researchers to go a bit on the goal of creating a complete heart.
Instead, researchers will have to rely on the natural self
The tendency of tissue cells to weave blood vessels together and eventually connect everything in 3D
Processes that can be carried out within 24 hours.
\"We will print things in the order of tens of microns or hundreds of micrometers, and then the cells will go through their biological developmental reactions to self-
\"The organization is right,\" said Williams.
Most researchers don\'t wantsize, 3D-
Printed organs will become a reality at any time in the next 10 or even 15 years, but the Cardiovascular Innovation Institute continues to advance its establishment of 3D-
Printed Heart within ten years.
Williams expects the next generation of \"Biographer\" to be launched in December.
