Gene thought to make heart tissues turns out to make blood and muscles as well
New research out of the Lillehei Heart Institute at the University of Minnesota shows that by turning on just a single gene, Mesp1, different cell types including the heart, blood and muscle can be created from stem cells.

Identification of stem cells raises possibility of new therapies
Many diseases – obesity, Type 2 diabetes, muscular dystrophy – are associated with fat accumulation in muscle. In essence, fat replacement causes the muscles to weaken and degenerate.

Scientists make insulin-producing cells self-replicate
(Medical Xpress)—Scientists have discovered a hormone that causes the body's insulin-producing factories, beta cells, to churn out more of themselves. Having enough insulin is critical to regulating the amount of sugar ...

Fusion and cell death in the development of skeletal muscle
(Medical Xpress)—Membrane fusion is a highly regulated event, both inside cells, and between them. From the moment a sperm first fuses with an egg, subsequent developmental events depend upon its proper ...

Uncleaned cells mean weak muscles
The protein complex mTORC1 promotes muscle growth. However, should this complex remain constantly active, it impairs the ability of the cells to self-clean, causing myopathy. Scientists working with Markus ...

Study discovers that stem cell senescence drives aging
Declining levels of the protein BubR1 occur when both people and animals age, and contribute to cell senescence or deterioration, weight loss, muscle wasting and cataracts. Mayo Clinic researchers have shown that adult progenitor ...

Skeletal muscle
Skeletal muscle is a form of striated muscle tissue existing under control of the somatic nervous system. It is one of three major muscle types, the others being cardiac and smooth muscle. As its name suggests, skeletal muscle is linked to bone by bundles of collagen fibers known as tendons.
Skeletal muscle is made up of individual components known as muscle fibers. These fibers are long, cylindrical, multinucleated cells composed of actin and myosin myofibrils repeated as a sarcomere, the basic functional unit of the cell and responsible for skeletal muscle's striated appearance and forming the basic machinery necessary for muscle contraction. The term muscle refers to multiple bundles of muscle fibers held together by connective tissue.
