A lot of blood is shed every day. Many lives are being saved when that shed blood is replaced. Donated blood is only good for a few weeks. Also there is the worry about contamination (HIV, Aids, etc.). What the world needs is a way to manufacture and deliver blood as needed.
Our Defense Department's research division (DARPA) wants a a self-contained system that could turn out 100 units of universal blood a week for eight weeks. The system needs to withstand war front conditions and be not much bigger than a refrigerator.
That task and $1.95 million was assigned to Arteriocyte less than two years ago. (see Popular Mechanics, Dec 2008 - Bringing Stem Cells to War: Meet the Blood Pharmers). The technology, called Nanex, uses a nanofiber-based structure that mimics bone marrow in which blood cells multiply, according to the company. (cnet News)
This week an initial shipment of their pharmed blood product was sent to the Food and Drug Administration for an independent evaluation. If approved, their cost of $5000 per unit of manufactured blood will need to be reduced.
Still, given the price tag of transporting and storing donated blood, Darpa’s betting that a unit of pharmed blood will make financial sense once it costs less than $1,000. Wired
