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 ...

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.

Muscle
Muscle (from Latin musculus, diminutive of mus "mouse") is the contractile tissue of the body and is derived from the mesodermal layer of embryonic germ cells. Muscle cells contain contractile filaments that move past each other and change the size of the cell. They are classified as skeletal, cardiac, or smooth muscles. Their function is to produce force and cause motion. Muscles can cause either locomotion of the organism itself or movement of internal organs. Cardiac and smooth muscle contraction occurs without conscious thought and is necessary for survival. Examples are the contraction of the heart and peristalsis which pushes food through the digestive system. Voluntary contraction of the skeletal muscles is used to move the body and can be finely controlled. Examples are movements of the eye, or gross movements like the quadriceps muscle of the thigh. There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.
