Scientists 'print' 3-D object with stem cells
PARIS (AFP) - Scientists on Monday said that for the first time they had printed 3-D 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.
They are touted as a source of replacement tissue, fixing nearly anything from malfunctioning hearts and lungs, to damaged spines, Parkinson's disease or even baldness.
