Promyelocytic leukemia nuclear bodies (PML NBs) are dynamic nuclear organelles. They range from 0.1um to 1um in size and exist in most of mammalian cell types. The functions of PML NBs are indicated ...

High resolution image of toxicysts, extrusive organelles, (sometimes called extrusomes in protistan lingo) in the proter (or anterior daughter) of a dividing cell. Toxicysts can be very long and are a...

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...
