Researchers in the UK plan to make what’s being hailed as an unlimited supply of blood for transfusions using discarded stem cells found in human embryos. They’ll test embryos discarded from in vitro fertilization (IVF) treatments to find those with embryonic stem cells that will make O-negative blood, which is the one type that can be transfused into anyone without being rejected…

Supplies of blood available for life-saving transfusions are limited. Local and regional pleas for blood by the Red Cross, owing to critically low levels, have become routine in the past decade. There’s more to it all than just giving blood. There are a host of tests that must be run on donor blood to make sure it is free of infection. And blood has a limited shelf life. Blood stored for 29 days or more (nearly 2 weeks less than the current standard for blood storage) is more likely to cause infection in transfusion patients, a study last year found.

Embryonic stem cells have the ability to become all the cells of the body. The idea is that harnessing their power would allow infinite production of what’d being termed “synthetic” blood that would be free of any infections that sometime plague blood supplies.

“In principle, we could provide an unlimited supply of blood in this way,” said team member Marc Turner, director of the Scottish National Blood Transfusion Service.

This is a fascinating and exciting time to be alive – and considering the wonders of modern science. I’ve mentioned it in older posts; but – starting with the pioneering work in genetics by Craig Venter – I’ve discovered what would be my career if I was just starting out in life. Computational analysis focused on medicine and science in general.

Yeah – I’d still be a geek.
