We move one step closer to a future where doctors can only twist the replacement organs made from your own cells, with Israeli researchers expressing that they have only 3D printed with a whole heartbeat with biological materials
you need a heart transplant, you have to wait for an available and appropriate organ from the other person's body, and the organs do not always last .
This week, scientists from Tel Aviv University in Israel announced that they made progress toward Alternative Solution
Using a bio-ink gel derived from the fatty tissue "reprogrammed" as stem cells , they are 3D prints of a tiny, heart heart for three hours.
"This is the first time anyone has been successfully recorded and printed with a full heart full of cells, blood vessels, ventricles and chambers," said Tal Dvir's author in a statement from university.
The heart, about the size of the rabbit, is too small for a man, and the researchers are still figuring out how it's bent
But the process used to create it shows potentially for a day to be able to 3D print patch and possibly full transplants, Professor Dvir said.
He said that it may mean that patients will no longer have to wait for transplants or take drugs to suppress their rejection.
"Instead, the required organs will be printed, fully personalized for each patient." "Perhaps, in ten years, there will be organ printers in the world's finest hospitals, and these procedures are performed regularly."
Making a chemical heart, it started
According to research published in German Wiley-VCH notes, researchers used fatty tissue taken from b
Cellular materials of the issue were then isolated and the cells were genetically "reprogrammed" to become pluripotent stem cells – these are cells that can result in all types of cells that make up the body.
The remaining cells are processed in a "thermoresponsive hydrogel" which becomes stronger in heating the temperature of the human body (37C).
The mixture of hydrogels and stem cells was injected into 3D printers cardiac tissue based on anatomical data from CAT scans.
