Stem Cell Growing in 3D Printed Molds, Leads to Breakthrough

3D Printing has been helping along various research foundations in a number of very interesting ways. One such example which has emerged recently could turn out to be groundbreaking. Researchers at Rockefeller University have come up with a way to organize embryonic stems cells as they grow. Previous attempts at this has left researchers baffled. What they did was use specialized 3D printed molds to grow the cells in. More details on just what they did exactly, can be found here: http://3dprint.com/8934/3d-print-embryonic-stem-cell/

This could mean major progress within the field, allowing for new cells to be grown in labs with only a few minor steps needed. Opinions? Below is an image of the separated cells:

You're wrong about the technology used for obtaining adhesive micropatterns. What was used is CYTOO's Arena products (www.cytoo.com). The process is using photolithography, not PDMS.
There is no 3D printing here.
