A man cut off his finger tip while working on a model plane. His brother, a medical research scientist, sent him a vial containing powdered pig bladder and told him to sprinkle on the severed finger tip. It grew back -- "flesh, blood, vessels and nail" -- in four weeks.
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.
"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.
"Somehow the matrix summons the cells and tell them what to do," Badylak explained. "It helps instruct them in terms of where they need to go, how they need to differentiate - should I become a blood vessel, a nerve, a muscle cell or whatever."
Scott Pruitt, the Trump administration’s top environmental official, privately met with the CEO of Dow Chemical just before reversing the EPA’s efforts to ban a widely used Dow pesticide.
