4/6/14 Health News: Development of Safe Artificial Blood ♦ Discovery Could Spawn Treatments for Cancer or Common Cold ♦ Self-healing Muscle Grown in the Lab

FDA Study Findings Could Facilitate Development of Safe Artificial Blood
The results of a study by scientists at the US Food and Drug Administration could help to simplify the design of a therapy for certain complications of sickle cell anemia, malaria, and other diseases in which red blood cells break apart. The finding also offers important insights into the development of safe and effective hemoglobin-based oxygen carriers for use in treating individuals suffering significant blood loss due to trauma. The potential therapy would use the blood protein haptoglobin to block the highly destructive chemical reactions triggered by hemoglobin when it escapes red blood cells that have broken apart.

Cell Metabolism Discovery Could Spawn Treatments for Cancer or Common Cold
Scientists at UCLA’s Jonsson Comprehensive Cancer Center have published the first study that explains how viruses reprogram the cells they invade to promote their continued growth within an organism. This knowledge could have implications in cancer treatments based on similarities between viruses and cancer cell mechanisms, and even lead to drugs that could inhibit the virus that causes the common cold.

Self-healing Muscle Grown in the Lab

Scientists have grown living muscle in the lab that not only looks and works like the real thing, but also heals by itself - a significant step in tissue engineering. Ultimately, they hope the lab-grown muscle could be used to repair damage in humans. So far trials have tested this out in mice.. The Duke University researchers say their success was down to creating the perfect environment for muscle growth - well-developed contractile muscle fibres and a pool of immature stem cells, known as satellite cells that could develop into muscle tissue.
