Tiny cellular antennae key to fat formation in muscle


Like it or not, as we age, our muscle cells are slowly exchanged, one by one, for fat cells. This process quickens when we injure a muscle, and an extreme form of this process is also seen in muscle-wasting diseases such as Duchenne muscular dystrophy (DMD). Now, scientists have shown that cellular antennae called cilia, found on fat-forming cells interspersed in muscle, play a key role in this muscle-to-fat transformation. 📍
