Self-Healing Engineered Muscle Grown in the Laboratory
Here are the highlights of the story, which is to be published next week in PNAS and under embargo until 3:00 pm EST on Monday, March 31.:
- First time lab-grown muscle has been shown to heal itself both in a dish and in an animal
- Implanted "window" in skin flaps on the backs of mice let researchers observe its development
- Engineered muscle more than 10 times stronger than any previously grown
- First time lab-grown muscle has rivaled the strength of native neonatal tissue
- And now the real stars of the show - the images and video
Video: After veins grow into the implanted engineered muscle fibers, blood cells can be seen traveling through them, sustaining and nourishing the new tissue.
