While we are on the subject of stem cell therapies, here is an article from Betterhumans on the subject. Research shows that stem cells cultivated from a patient could be used to treat regenerate muscle lost to degenerative conditions. Unlike similar work that regenerates damaged heart tissue (and was recently blocked by the FDA), this muscle regeneration is in the very early stages. Still, it shows that there should be a wide range of regenerative therapies resulting from stem cell work that should be available before the end of the decade. This is very promising indeed, and could have very beneficial effects on our future longevity. This is why we must stand up to support and defend medical research; it is in our own best interests to age in a world with stem cell medicine rather than one without.
