Taiga Biotechnologies may wipe out blood banks as we know them. The Aurora, Colorado-based startup has developed and licensed stem-cell technologies that can grow an almost limitless supply of red blood cells. If they work (and it’s looking likely) the technologies could be used to provide blood where it’s needed the most—ambulances and disaster sites, for instance. Eventually, they could even replace some or all of the 39,000 units of blood transfused into patients every day.
