Narrator: This is Science Today. Imagine being able to receive an infusion of molecules that could reverse your aging muscle tissue. Researchers at the University of California, Berkeley are working towards this reality. Bioengineer Irina Conboy says they've been able to significantly turn back the clock on old human muscle by manipulating biochemical pathways in adult stem cells.
Conboy: There is no ethical consideration because we are not injecting cells into people and certainly the cells are not derived from an embryo. It will be actually a small molecule which is similar to many currently approved small molecules, which are used for a variety of treatments, for example cancer treatment. And it will be a cocktail of molecules, so you can look at this as a very, very sophisticated vitamin supplement.
Narrator: But first, the researchers are looking to receive funding to work with a collaborating clinician.
Conboy: The idea would be to join forces with the person who actually is a gerontologist and does work in clinic with elderly and then go through the safety screening, which is required for FDA approval of the treatments.
