Researchers have found that red blood cells cannot repair tears in their surfaces due to the lack of internal membranes, confirming a decade-old hypothesis. In contrast, muscle cells can rapidly repair tears by sealing them with a large internal membrane.
The FKHR gene helps myoblasts fuse into muscles, but a deficiency contributes to muscle cancer. FKHR's dual role is regulated by different processes depending on the cell context.
Researchers have pinpointed a genetic defect in the phospholamban protein as the cause of inherited dilated cardiomyopathy. The discovery may lead to targeted treatment for this disorder, which affects 4.7 million Americans and costs $17.8 billion annually.
Dr. Rossant and colleagues find that Flk1 and Tal1 proteins steer embryonic cells towards endothelial, hematopoietic, or smooth muscle fates. The study provides further evidence for a common hemangioblast progenitor cell, which can differentiate into the three cell types.

A recent study has provided the first direct evidence that transplanted muscle cells can form muscle fibers and blood vessels in damaged hearts. Satellite cells from patients' thigh muscles were injected into their heart tissue, surviving and differentiating into mature muscle fibers without triggering an immune reaction.
Researchers have found that deacetylase inhibitors enhance muscle gene expression and formation in human and mouse myoblasts. This discovery may lead to methods to induce muscle growth, regeneration, and repair in adults with muscular dystrophy.
Penn researchers have identified a key gene, Hop, that plays a vital role in regulating the development of heart cells. By inhibiting the expression of another important regulator, serum response factor (SRF), Hop protects cardiac muscle cells from over-development and fatal abnormalities.
Researchers at Johns Hopkins Medicine have successfully created a biologic pacemaker using gene therapy in guinea pigs. The new pacemaker allows heart cells to regulate their own rhythm, potentially providing an alternative to traditional electronic pacemakers for patients at high risk of infection or with limited space for implantation.
A boy with Duchenne muscular dystrophy (DMD) and severe combined immune deficiency (SCID) had bone marrow donor cells present in his muscle fibers 13 years after a transplant. Mesenchymal stem cells from the donor's bone marrow may be continuing to produce muscle cells, potentially reducing disease severity.
Researchers successfully converted circulating smooth muscle progenitor cells into functional smooth muscle cells, which could help address interventional cardiology problems. The study may pave the way for therapeutic angiogenesis by preventing or eliminating the adhesive properties that contribute to plaque formation.
Researchers at Dana-Farber Cancer Institute discovered a chemical switch called PGC-1 that can transform fast-twitch fibers into slow-twitch fibers, increasing muscular endurance. This finding could lead to the development of a new drug to manipulate muscle fiber type and improve muscular function in patients with medical conditions.
Researchers at the University of Pittsburgh School of Medicine have developed a promising new therapy for urinary incontinence using muscle-derived cells. The therapy, which uses genetically engineered muscle cells to replace damaged bladder muscles, shows long-term effectiveness in improving bladder function.
Researchers at the University of Pittsburgh have discovered a unique population of muscle stem cells that can be transplanted into mice with Duchenne muscular dystrophy, delivering the key protein dystrophin and improving muscle regeneration.
