NCBI Organism Classification
Phodopus
Biological Process
single fertilization
Cellular Component
microvillus membrane
Scanning electron micrograph showing a lateral view of sperm penetration of a hamster oocyte during vitro fertilization. As the membrane of the sperm head fuses with that of the oocyte, the microvill...

Biological Process
spermatogenesis
Cellular Component
mitochondrial crista
In insect spermiogenesis, mitochondrial cristae disappear and a proteinaceous material is deposited in filaments that become closely packed paracrystalline arrays. In this micrograph, crystals are pr...

NCBI Organism Classification
Drosophila melanogaster
Biological Process
germ-line cyst formation
Cellular Component
P granule
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...

NCBI Organism Classification
Phallusia mammilata
Biological Process
fertilization
Cellular Component
spindle
The time lapse movie spans fertilization, ooplasmic segregation, and early divisions in the egg of the tunicate Phalusia mammilata. Contrast is provided by both polarizing microscopy and differential...

NCBI Organism Classification
Nephrotoma suturalis
Biological Process
male meiosis chromosome segregation
Cellular Component
cytoskeleton
The events of meiosis I and II in a living insect spermatocyte beginning with the breakdown of the nuclear envelope at diakinesis through to the completion of cytokinesis. Testes from the Crane fly N...

NCBI Organism Classification
Drosophila melanogaster
Biological Process
germ-line cyst formation
Cellular Component
P granule
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...

NCBI Organism Classification
Drosophila melanogaster
Biological Process
smoothened signaling pathway
Cellular Component
P granule
Boi (red) localizes predominantly to apical cells in Drosophila wild-type germaria but not in germaria with UAS-boi[RNAi] expression (CIL#13742). Germ cells are identified using anti-Vasa (blue). Imag...

NCBI Organism Classification
Drosophila melanogaster
Biological Process
smoothened signaling pathway
Cellular Component
P granule
Boi (green) localizes predominantly to apical cells in Drosophila wild-type germaria but not in boi[e] mutant germaria (CIL#13740). Germ cells are identified using anti-Vasa (blue). Image is Fig 2B in...

NCBI Organism Classification
Drosophila melanogaster
Biological Process
smoothened signaling pathway
Cellular Component
P granule
Boi (green) no longer localizes predominantly to apical cells in Drosophila boi[e] mutant germaria (compare with CIL# 13739). Germ cells are identified using anti-Vasa (blue). Image is Fig 2C in J Cel...
