Analysis of Titin in Red and White Muscles: Crucial Role on Muscle Contractions Using a Fish Model

Figure 1

Red muscle (R) contains more lipids than white muscle (W). (a) The dotted line shows a cross-section near the cloaca of Tilapia. (b) Cross-section; red muscle is located on the lateral sides of the trunk (arrows), while white muscle is located on the back and ventral parts of the fish. (c) Oil-red O staining of a frozen section; red muscle contains more lipids than does white muscle. (d) More intracellular lipid droplets were seen in red muscle.
