Imagine being able to draw an organ in a CAD-style program and
print it. While this exact scenario is still probably some years
away, Organovo, the innovative San Diego-based medtech company
founded in 2007, is on its way. Partnered with the product
development firm Invetech, Organovo was the first to make the
leap from two-dimensional bioprinting to the three-dimensional
realm. Together, the collaboration has been involved in all
aspects of research, development and logistics to bring 3D
bioprinting to medical research facilities. Which begs the
question…  …How Do You Build A Liver?   How to print a tissue.
Source:  The key ingredients are human cells and a hydrogel,
scaffold, or support matrix, the biological “glue” binding the
cells together. The organ sculptor begins by drawing the liver
in a user-friendly graphical interface. This bio-blueprint is
then fed to the printer, which consists of two printheads, one
to place the human cells, the other to position the support
matrix. While designing the Novagen
