Scientists on Monday said that for the first time they had printed 3D objects using human embryonic stem cells, furthering the quest to fabricate transplantable organs.
Once fine-tuned, the technology should allow scientists to make three-dimensional human tissue in the lab, eliminating the need for organ donation or testing on animals, they reported.
Human embryonic stem cells (hESCs) can replicate indefinitely and become almost any type of cell in the human body
We are able to print millions of cells within minutes,” co-author Will Shu of the Heriot-Watt University in Edinburgh, told AFP.
“The printer is similar to the size of a standard desktop-size laser printer.”
The living cells are printed onto a culture dish and left to aggregate together to form “what we call a spheroid, like… a little ball,” said Shu
