Exploring the Evolutionary Strategies of Skeletal Muscle Growth and Aging in Teleost Species with Determinate and Indeterminate Growth

Unlike mammals and birds, which stop growing after reaching adulthood, many fish keep growing throughout their lives. We studied muscle growth in different fish species and found that some stop growing early, while others continue into adulthood. This difference is linked to how muscle stem cells behave and develop over time. We also discovered that the surrounding environment of these cells plays a key role in controlling their activity and growth. Understanding these processes could help find new ways to improve muscle growth and combat aging in different situations.
