3D bioprinting

---

One of the biggest challenges for the bioengineering field in bioprinting functional tissue has been the inability to recreate the complex architecture of vascular networks that supply blood and nutrients. That meant scientists needed to get creative.

Bioengineer Shaochen Chen has developed a method of 3D printing live human tissue that could one day be used to heal damaged spinal cords, hearts, and other vital organs. And, because his technology uses stem cells, the transplant tissue can be patient specific. Now, he's using his technique to help researchers Alysson Muotri and Karl Wahlin understand brain and eye developm

Bioengineers have cleared a major hurdle on the path to 3D printing replacement organs and tissues with a new open-source technique for bioprinting tissues and templates with exquisitely entangled vascular networks similar to the body's natural passageways for blood, air, lymph and other vital fluids.
