This is a cool story about research out of Eindhoven University of Technology in the Netherlands. Researchers have found a way to grow muscle tissue and blood vessels in a uniform direction. This may not seem like a big deal, but the implications are big because in the past all of the muscle tissue that has been grown has generally been of random orientation, which cannot be used functionally to lift a load. Surprisingly their new method involves velcro and doesn’t require any type of growth factors to be added to the stem cells they are using. Follow the link to read more about it.
It’s interesting to think that some day you may not have to worry about torn muscles or ligaments as much and a doctor will just be able to go in and add some more muscle to strengthen the injured area back up.
