Pop Science reports that within fifteen years it may be possible to regenerative new tissue where and when its needed using natural processes:
Glenn Larsen, the chief scientific officer at Hydra Biosciences in Boston, has been chasing this regenerative dream for the past four years. With help from a team of Harvard University researchers, Larsen and his colleagues are developing protein-based drugs that encourage the regrowth of muscle tissue that has died after a heart attack.
“The heart is constantly secreting chemical factors it needs to maintain itself,” Larsen explains. “All we’re doing is trying to enhance that.” Fair enough, but his company is likely to be the first to take the revolutionary step of harnessing these natural processes to grow new tissue where and when it is needed. With restored heart-muscle function, patients would be able to resume swimming, running or just gardening much sooner. They would also be less prone to congestive heart failure, which kills more than 50,000 Americans every year.
