This startup preserves your cells for the future, to capitalize on medical breakthroughs yet to come


Silene Biotech wants to help you grow a new heart or liver, in case those organs fail when you get older. The ambitious Seattle startup — founded two years ago and a member of the 2017 TechStars Seattle class — today is launching a new service that freezes and stores your white blood cells so they can be used decades later when troubling ailments set in.

The big idea? You could preserve the cells from your 23-year-old body for use when you are 65, and possibly facing life-threatening diseases.
