An endless supply of blood, including the rare AB-negative, can be derrived from embryonic stem cells. Harvesting is controversial, yet done once acorrding to lead researcher Robert Lanza. "The beautiful thing is that you start with one line, expand them indefinitely, and generate as many as you want," Lanza made clear.
Scientists used a four-step, and rather complex, process that turned stem cells into red blood cells capable of carrying as much oxygen as normal blood. "We literally generated whole tubes in the lab, from scratch," Lanza said.
Hospitals and blood banks will have an ample supply from labs opposed to human donors, if this can be duplicated in a cost-effective manner. : : Angie Seegers : :
