Tissue Regeneration Coming
Science is making progress in the ability to grow organs on demand and even manufacture them. They might even be able to grow fresh limbs for people who lost them.
Dr. Atala, one of the pioneers of regeneration, believes every type of tissue already has cells ready to regenerate if only researchers can prod them into action. Sometimes that prodding can look like science fiction.
Emerging from an everyday ink jet printer is the heart of a mouse. Mouse heart cells go into the ink cartridge and are then sprayed down in a heart shaped pattern layer by layer.
Dr. Atala believes it’s a matter of time before someone grows a human heart.
“The cells have all the genetic information necessary to make new tissue,” Atala explained. “That’s what they are programmed to do. So your heart cells are programmed to make more heart tissue, your bladder cells are programmed to make more bladder cells.”
