Figure 432 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Smooth muscle of mouse epididymal duct. The area within the rectangle is shown at highe...

Figure 434 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Vascular smooth muscle cell in cross section shows myosin and actin filaments distribut...

Rat cardiomyocytes were plated and stained for actin (in red), desmin (in green) to reveal the intermediate filament essential for the structural integrity and function of muscle, and DAPI (in blue) t...

The C2C12 cell line, a mouse myoblast line, was used here to study the regulatory factors in myogenic differentiation. After cultured in differentiation medium for 3 days, these cells differentiated i...

Portion of a single computed slice through a tomographic reconstruction of the myocardium of the left ventricle of a normal mouse. For more information see: Hayashi, T., Martone, M. E., Yu, Z., Thor,...

Single computed slice from a tomographic reconstruction of a 500 nm section through the middle free wall of a cardiac myocyte from the left ventricle of an adult mouse (6-8 months of age), stained wit...

Light micrograph of a longitudinal section of the epididymis. The lining of the duct consists of pseudostratified epithelial cells, which have prominent microvilli on their free surface extending in...

Transmission electron micrograph of longitudinal section of rat heart ventricle. A portion of a nucleus is seen at upper right, with a region of closely packed mitochondria extending to lower left, fl...
