3D Printed Human Heart By 2023, Says Top Scientist

RATE THIS! +38
Posted in Science on 12th Mar, 2014 12:16 AM by AlexMuller

A scientist named Stuart K. Williams is leading a team responsible for an extremely ambitious project; to print the human heart. Williams, who is the Scientific Director of the Cardiovascular Innovation Institute at the University of Louisville, believes that within a decade, perhaps sooner, 3D printed human hearts will be available for transplant.

 
“For bioprinting it is the end of the beginning as bioprinted structures are now under intense study by biologists. Dare I say the heart is one of the easiest to bioprint? It’s just a pump with tubes you need to connect,” said Williams.
 
Williams’ team includes 20 top scientists working with him on this project, and they have been making tremendous progress already. In fact, the 3D bioprinter which will one day be responsible for the first printed human heart, is already under construction. Once the printer is completed, the team can start testing out various tissue samples.
 
Printing out heart tissue is the easy part. It’s the printing of an entire heart with valves and blood vessels, appropriately placed, which is more difficult. Williams realizes the difficulties he faces, and has been making a lot of progress.
 
Basically his team needs to figure out a way to get the printed cells, especially the blood vessels, to naturally organize themselves so that they connect to the recipients own blood vessels. This will allow the heart to continue to receive a blood supply, and survive. Williams describes his vision of how such a 3D bioprinted heart will materialize,
 
“A patient enters the operating room and tissue is removed (we think fat is the best source) and regenerative cells isolated. The cells are then mixed with solutions that contain extracellular matrix molecules and other factors and placed in the bioprinter. The bioprinter then prints the heart.”

It seems that the efforts to perform bio printing of the entire hearth are going very well - indeed, this is a relatively simple organ in comparison with some other, good news for transplantations

Considering that Heart disease is the number one killer in many countries, any progress in this field could be "a major win for those looking to extend the human life span."

There are already so many heart procedures. Heart surgery is now common and - done to correct problems with the heart - this new developments will fit here Reply

Yes, it is possible to repair or replace heart valves and to replace a damaged heart with a healthy heart from a donor Reply

This seem to be the case and many aspects of regenerative medicine are still to be perfected before any human trials start. Reply

One recent advance - 3D printing of tissue with blood vessels- is the key breakthrough leading to creating full size artificial organs, including heart. Great progress! Reply

I agree that recent progress in bioprinting supports the claim that "For bioprinting it is the end of the beginning as bioprinted structures are now under intense study by biologists." Reply
