Currently, heart transplantation is the only reliable means of replacing lost muscle tissue following a heart attack but is limited by the number of donors and cost. Because heart muscle cells are not rapidly replaced following a heart attack, researchers have been investigating stem cell technology in hopes of replacing damaged cells. [Transplantation Review (Orlando). 2009 Jan; 23(1):53-68]
Donor cell transplants emerge as a promising strategy to regenerate diseased heart muscle cells (called cardiomyocytes). However, stem cell therapy has produced inconclusive and contradictory results. [Current Opinion Organ Transplantation 2009 Feb;14(1):79-84] There are many drawbacks and hurdles, including high cost, that need to be overcome before stem cell therapy for the heart can be offered in the clinic. [BioDrugs 2008; 22(6):361-74]
Now, for the first time, researchers have demonstrated that heart muscle cells (cardiomyocytes) are slowly replaced over time, about 1% per year, not fast enough to restore healthy function to the heart following a heart attack, but sufficient to demonstrate regenerative potential towards the introduction of several drug combination products.

The luster surrounding the red wine molecule resveratrol isn’t fading, but the growing body of pseudoscience being created by online hucksters, as well as exaggerations by scientists who have a commercial interest in a resveratrol-like drug, casts a pall over the excitement of a maybe-it’s-real-this-time anti-aging pill.
