High resolution image of a monoclonal antibody raised in mouse to an antigen called C6 found on the surface of Paramecium. As seen in this micrograph the gold labelled antigen heavily labels the cilia...

Smoothened (Smo; green), a downstream effector of Hedgehog (Hh), is expressed in most cells of the wild-type Drosophila germarium including follicle stem cells, but is excluded from Boi- and Hh-expres...

The E-face of the plasma membrane of a semicell engaged in the synthesis of the secondary wall. Hexagonal arrays of rosettes of varying size and shape can be observed. The large circular indentation...

The Hedgehog (Hh) pathway is activated in follicle stem cells of animals lacking boi (CIL# 13757), relative to wild-type Drosophila (this image), based on activated cubitus interruptus (ci) staining (...
