Special Protein May Restore Youthfulness to Various Tissue

Studies using a protein called Gene Differentiation Factor 11 (GDF11) are showing promise for regenerating aging brain, heart and muscle tissue. While it's only been shown in mice for now, they're predicting human trials within the next 3-5 years. Could this be a long-sought answer for neurodegenerative disease, heart disease, or even traumatized muscle tissue? I'd read if I were you!!
