Primary aortic endothelial cells from transgenic mouse embedded in 3D collagen gels. Cell was fixed with 3% paraformaldehyde and stained with mouse antibody to phosphomyosin regulatory light chain (re...

Extrusion of an apoptotic cell from an HBE monolayer as shown by confocal Z-series. This set of images shows late extrusion events (early and middle events are CIL# 37908 and 37909). The bioactive lip...

Apoptotic cells produce and transmit the bioactive lipid sphingosine-1-phosphate (S1P) during extrusion. This set of images shows that extrusion is blocked, as well as accumulation of S1P around the d...

Apoptotic cells produce and transmit the bioactive lipid sphingosine-1-phosphate (S1P) during extrusion. In this confocal Z-series, an antagonist to the S1P receptor, S1P2, was used to plock signaling...

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...

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...

Cardiac muscle, particularly from the left ventricle, is rich in mitochondria since the heart requires an efficient continuous source of energy. In this highly magnified image, showing the length of t...
