A bioengineering team from Carnegie Mellon University
and the Pittsburgh School of Medicine have presented a way to employ techniques based on inkjet printers to help stem cells become bone tissue cells. The team uses a set of inkjet-style streams
to shoot little bits of proteins (like droplets of printer ink) on top of nurturing proteins (think of them as the paper) in a certain pattern. Then the team drops stems cells on top of the whole concoction, which depending on what bio-ink was used, can turn into bone-type cells or potentially even other cell types. While human trials are still a ways off, let's just hope that bio-ink cartridges aren't nearly as much of a scam as regular inkjet cartridges
are when they reach that point.
