Current treatments, such as blood substitutes, breathing masks, and tubes, aren’t always effective as well since they still rely on the lungs to function or require time to properly administer.

Blood protein from genetically modified rice could ease demand for blood donations.

Genetically modified grains of rice produce a key component of human blood in an attempt to provide an alternative to donations. The protein, extracted from rice plants containing human genes, could be used in hospitals to treat burns victims and help patients who have suffered severe blood loss.
