That powder is a substance made from pig bladders called extracellular matrix. It is a mix of protein and connective tissue surgeons often use to repair tendons and it holds some of the secrets behind the emerging new science of regenerative medicine.As if that wasn't enough to blow your mind, they are also regrowing entirely new organs using an ink jet printer! It sounds ridiculous but you can see for yourself in the video "Manufacturing Body Parts".
"It tells the body, start that process of tissue regrowth," said Badylak.
Badlayk is one of the many scientists who now believe every tissue in the body has cells which are capable of regeneration. All scientists have to do is find enough of those cells and "direct" them to grow.
Gone are the days when people's fears of the future involved mass cloning and the harvesting of organs from clones. With this technology all that is necessary is the patient's own cells.
