While much has been said on the topic of 3D printing within the context of the maker movement, it is in the medical world where arguably the most important advances are being made. Scientists at the Heriot-Watt University in Scotland have recently proven they can print human embryonic stem cells, a breakthrough which has the potential to revolutionise organ replacement in the coming years.
Dr. Shu says, “People have developed different technologies for printing and have been able to print, for example, a dog’s stem cells, taken from the marrow and different sources but those cells cannot be replicated indefinitely outside the body. That means you have to take stem cells every time if you need them. A human embryonic stem cell, however, can replicate indefinitely outside the body.”
Very fascinating work. Has the potential to end drug testing on animals as well as revolutionizing organ transplants in humans.
