Hedgehog (Hh, red) is transcribed in apical cells of the Drosophila wild-type germarium (CIL# 13755, 13744). In the absence of boi (boi[e] mutant), Hh protein is redistributed from apical cells to the...

Hedgehog (Hh, red) is transcribed in apical cells of the Drosophila wild-type germarium (CIL# 13755 and this image). In the absence of boi (boi[e] mutant), Hh protein is redistributed from apical cell...

In the absence of boi (boi[e] mutant), Hedgehog (Hh, red) is redistributed from apical cells to the extracellular space of the local follicle stem cell niche (CIL# 13744, 13745). Expression of Boi in ...

High resolution image of Halteria fixed in cacodylate-buffered fixative and stained. The round, dark bodies, possibly pigment granules, which were transparent in other preparations are electron-opaque...

Grazing section through an accumulation of uncoated cupulas in the process of attachment to and fusion with a food vacuole membrane. The small round pores apparently represent early stages of fusion o...

A DV-III contains a thick continuous glycocalyx (polysaccharide coat) on the luminal side of its membrane as well as paracrystalline material, both provided by the fused lysosomes. The latex beads ind...

A high resolution image of a cell actively undergoing endocytosis that develops an extensive layer of vesicles and cisternae composed for the most part of smooth undecorated membrane. The uncoated cis...
