Using 3D printers in regenerative medicine

A colleague of mine, Thomas Deneuville told me about this breakthrough research in using 3D printers to create tissue templates for creating organs in regenerative medicine (was published in Nature Materials).

Dr. Anthony Atala talks about "Growing organs" by printing, knitting, weaving cellular structures (and in some cases printing directly onto the organ during surgical procedures). These videos overlap, but the first one is dated 2009, and the second one is dated 2011:

In this video, they can scan and directly print these cell lines to the organ (screenshot of a frame in this video, and video just below it):

Last, I believe this research was published this July in Nature Biotechnology. The researchers at Caltech and Harvard were able to print and grow these artificial jellyfish, called "Medusoid," that they hope to use to create heart muscle or “to clean up oil spills in a similar manner to the way a jellyfish filters out its food.”
