Boi (green) and Hedgehog (Hh, red) are expressed in apical cells of the Drosophila wild-type germarium (CIL# 13744). In the absence of boi (boi[e] mutant), Hh is redistributed from apical cells to the...

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...

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 ...

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 a mutan...

Boi (green) and Hedgehog (Hh, red) are expressed in apical cells of the Drosophila wild-type germarium. In the absence of boi (boi[e] mutant), Hh is redistributed from apical cells to the extracellula...

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...

Fluorescent micrograph of rat embryo fibroblast cell growing in serum stained to reveal actin stress fibres (red) and vinculin (component of focal adhesions) in green/yellow.

Colorized scanning electron micrograph of pollen on the anther of a hedge mustard (Sisymbrium officinale) flower. This plant is reputed to have various medicinal properties including its ability to tr...

Confocal micrograph of a mast cell in human eye with conjunctivitis. This image shows a single mast cell invading conjunctival tissue in response to an inflammatory agent or pathogen. The mast cell c...
