Regenerative MedicineInjectable Gel Helps a Repair Protein Rebuild Injured Muscle in Preclinical Study
An experimental injectable gel may help repair injured muscle by keeping a helpful protein available where it is needed. Researchers loaded the gel with Cripto, a protein that supports muscle regeneration by opposing signals that limit muscle growth. The gel formed at body temperature and released active Cripto for up to 28 days. In a preclinical muscle injury model, delivery through the gel improved signs of tissue repair, including muscle fiber size and levels of a muscle structural protein. A single injection of Cripto without the gel did not improve regeneration. The findings suggest that sustained delivery matters, not just the choice of protein. However, the abstract does not report strength, mobility, or human outcomes. This abstract-only summary describes an experimental approach, not a proven treatment for injuries or muscle loss with aging.
