Confocal micrograph showing the development of motor neurons in the mouse forelimb at 11.5 days post coitum. The transgenic mice expresses a transgene of the Hb9 gene containing a genetic insert of th...

The final morphogenesis of the cardiac outflow tract (OFT) depends on coordinated cell-cell interactions among the heart tip, migrating heart-anchoring cells (HANCs) and the dorsally growing cardiac o...

Confocal image of axons (green) making contact with muscle fibers at neuromuscular junctions. As seen here more than one nerve fiber initially contacts each muscle fiber. As development proceeds, the ...

Confocal micrograph showing the complex connectivity at the neuromuscular junction of Drosophila (fruit fly). Muscle fibers shown in red and nerve fibers into neruomuscular junction shown in blue and ...

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...

Transmission electron micrograph of the periphery of an atria mouse cardiac muscle. This micrograph shows how rich cardiac tissue is with mitochondria reflecting its greater dependence on cellular re...

High resolution overview of Opercularia coarctata with macronucleus, cytoplasm, and section of the oral area. Specialized rough endoplasmic reticulum with modification into decorated tubules that lie ...

Transmission electron micrograph of four longitudinally cut ventricle muscle fibers of mouse cardiac tissue. Muscle fibers are multinucleate celsl composed of myofibrils that contract when stimulated...

Transmission electron micrograph of a blood vessel in the atria of a mouse cardiac tissue. This image is a close up of a red blood cell in a blood vessel.

In Opercularia coarctata specialized ER modified into decorated tubules lie on the surface of myonemes. The composition and function of the decorations have not been determined but they may be calcium...
