3D-Printed Human Embryonic Stem Cells Created for First Time -
Scientists used 3D printing to form these aggregates of embryonic stem cells, shown here at 24 hours (left) and 48 hours (right) after printing.
Imagine if you could take living cells, load them into a printer, and squirt out a 3D tissue that could develop into a kidney or a heart. Scientists are one step closer to that reality, now that they have developed the first printer for embryonic human stem cells.
In a new study, researchers from the University of Edinburgh have created a cell printer that spits out living embryonic stem cells. The printer was capable of printing uniform-size droplets of cells gently enough to keep the cells alive and maintain their ability to develop into different cell types. The new printing method could be used to make 3D human tissues for testing new drugs, grow organs, or ultimately print cells directly inside the body.
Human embryonic stem cells (hESCs) are obtained from human embryos and can develop into any cell type in an adult person, from brain tissue to muscle to bone. This attribute makes them ideal for use in regenerative medicine — repairing, replacing and regenerating damaged cells, tissues or organs.
