Stem Cells Printed in 3-D with Inkjet Devices
The creation of implantable human organs with an ink-jet printer isn't as far-fetched as it might seem, a materials scientist said—at least in the future.
Scientists already use ink-jet cartridges to "print" stem cells into exacting patterns, and now engineers are taking the technology to a whole new dimension—quite literally—by exploring ways to print 3-D structures of cells.
"It's a milestone that we can print all types of cells onto a surface with an ink-jet printer without them dying, even stem cells," said Paul Calvert, a materials scientist at the
Calvert, who details the state of cell-printing research in the Oct. 12 issue of the journal Science, said 3-D techniques could help unravel the mysteries of cell-to-cell communication and, perhaps in the distant future, manufacture human organs from scratch.
