boi controls follicle stem cell proliferation. Germaria from boi[e] mutant in which germ cells (blue, anti-Vasa) and differentiating follicle cells (red, anti-Fas3) are labeled. Stalks between the ger...

The Hedgehog (Hh) pathway is activated in follicle stem cells of animals lacking boi (boi[e]; this image), relative to wild-type Drosophila (CIL# 13756), based on activated cubitus interruptus (ci) st...

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...

Glial cells in the nerve cord of the annelid worm, Aphrodita aculeata are rich in 10 nm filaments, and desmosomes are abundant. Figure 89 from Chapter 3 (Junctional Specializations) of 'The Cell, 2nd ...

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.

Figure 436 from Chapter 16 (Cytoplasmic matrix and cytoskeleton) of 'The Cell, 2nd Ed.' by Don W. Fawcett M.D. Cytoplasm of a Sertoli cell from testis of the ground squirrel, Citellus lateralis in cu...

Colorized scanning electron micrograph of a human embryonic stem cell (gold) growing on a layer of supporting cells (fibroblasts). Stem cells are derived from very early embryos and can either be grow...
