Vitellogenesis: not only in the liver and not only in females

Vitellogenin (VTG) is an estrogen-dependent, females-specific yolk precursor protein naturally synthesized during the reproductive period in the liver of oviparous vertebrates. Released in blood, VTG is taken from the growing oocytes by micropinocytosis and used as nourishment

Tail regeneration in lizard is driven by key genes of the Wnt-pathway

The importance of lizards as models to analyze the process of organ regeneration is relevant since, differently from the classical amphibian models, these vertebrates are amniotes adapted to the terrestrial environment, therefore closer to mammals and humans.

Key genes for amniote organ regeneration detected in lizard transcriptomes shed new hope for limb regeneration in humans

While in water-adapted vertebrates (anamniotes: fish and amphibians) organ regeneration is relevant or outstanding, including in fins or limbs, in fully terrestrial vertebrates (amniotes: reptiles, birds and mammals) regeneration is absent or rare. Aside numerous anatomical and

How to measure maximum animal performance

Scientists are often interested in the performance capabilities of animals, measuring how fast they can run or how hard they can bite. This information helps scientists understand how the bodies of different animals work and how they
