Thought this was cute. These young lads were playing on this shelter, and the muscle man pose silhouetted nicely against the setting sun!

City of Hope scientists are delving into the intricacies of muscle cell metabolism to understand how those cells gain nutrients, generate energy and develop into muscle tissue. Janice Huss, Ph.D., assistant professor in the Department of Diabetes and Metabolic Diseases Research at City of Hope, and her team used three fluorescent dyes — red, green and blue — to visualize different parts of muscle cells, called myocytes, as they fuse together to form myotubes, the basic structures of muscle tissue.
The blue dye stains DNA in the oval nuclei. Red shows mitochondria, the power generators of cells, which are actively producing energy. Green marks a protein called PGC-1a, which controls genes that are important in muscle cell metabolism. The researchers’ work could lead to a better understanding of the factors contributing to muscle diseases, including heart disease, as well as diabetes and other metabolic syndromes.
