A new research breakthrough has enabled scientists to grow human tissue to repair or replace organs, and someday, maybe even limbs. Science correspondent Miles O'Brien reports.
Transcript:
MILES O'BRIEN: I am not sure when or why I thought it was a good idea to go for a bike ride on a 100-degree Texas afternoon with a 26-year-old Marine corporal. There I was eating Isaias Hernandez's dirt. No surprise, right? Well, take a look at his right thigh.
CPL. ISAIAS HERNANDEZ, U.S. Marine Corps: It looked like a chicken, like if you would take a bite out of it down to the bone.
MILES O'BRIEN: It happened in Iraq in 2004. He was badly injured in an artillery attack on his convoy.
CPL. ISAIAS HERNANDEZ: They patched it up because they said the other thank option would be amputation because they couldn't just leave my leg on with a hole in it.
