Hi Guys, Thanks for your interest! An update from Rejuvenation Technologies: The comment above is incorrect. Our claims were simply moved to a continuation patent, US 16/735,681, which has been granted, and our granted patents now cover all in vitro and in vivo applications of TERT mRNA-based telomere extension. If you'd like more info, please feel free to email [email protected]. Thanks again! Best regards, John
