Breakthru writes "In an important breakthrough, scientists at McMaster University have discovered how to make human blood from adult human skin. The discovery, published in the prestigious science journal Nature today, could mean that in the foreseeable future people needing blood for surgery, cancer treatment or treatment of other blood conditions like anemia will be able to have blood created from a patch of their own skin to provide transfusions. Clinical trials could begin as soon as 2012."
