Human Engineering - Printing human organs through 3D printer

Imagine a 3D inkjet printer printing a human kidney or a heart, sounds unimaginable? But it will be possible in future as demonstrated by Dr. Anthony Atala, director of the Wake Forest University Institute for Regenerative Medicine for TED, a group devoted to spreading ideas by bringing together technology, entertainment and design.

Even though there is a long way to go, it is possible to print human organs layer by layer using a 3D inkjet printer. The only difference is that instead of using the inkjet cartridge, cells will be used. If you still think it’s only theoretical and impossible to implement than the news is the researchers have already printed a quarter size two chamber hearts that start beating after four to six hours. The simpler organs like urethras and bladders are already built and implanted by researchers with the help of this program.

I am sure all of you like me must be thinking how is it possible? As Dr Atala from TED describes the complicated human engineering in simple words in an interview with CBC Radio's Quirks & Quarks,

All the cells in your body are already pre-programmed. There’s a genetic code within all your cells that drives them to do what they are supposed to do if you place them in the right environment.

The layers are made of the appropriate cells from patients own body on dissolvable scaffold that mature inside the body and connect with the blood vessels and nerves. This is surely a technology for human engineering which will change the face of medical science to a large extent as the patients will not have to wait long for the angel in the face of the donor for organ transplant. Now this is what we call amazing and revolutionary invention for the mankind.
