Stem cell again has created a breaking news. Only this time the news is associated with blood transfusion.

For the first time in the medical history, blood cells has been created outside the animal body using embryonic stem cells.

This making of red blood cells in a laboratory from a six-well plate of stem cells has been done by Robert Lanza, chief scientific officer at Advanced Cell Technology (ACT), a Worcester-based company and her associate at the Mayo Clinic and University of Illnois.

According to Robert Lanza, embryonic stem cells are a new source of cells that propagate and expand indefinitely into potentially inexhaustible source of red blood cells which can be of great help for human therapy.

This new technique is believed to be very promising and pioneering as limitations in the blood supply specially universal type O- negative blood can have a life threatening consequences for patients with massive blood loss.
