For the first time, scientists have turned human skin cells into transplantable white blood cells, soldiers of the immune system that fight infections and invaders. The work, done at the Salk Institute, could let researchers create therapies that introduce into the body new white blood cells capable of attacking diseased or cancerous cells or augmenting immune responses against other disorders.
