Analysis of bearded dragon model reveals a novel tooth replacement strategy that demonstrates the critical importance of epithelial patterning, cell migration, and putative stem cell functional specialization in tissue regeneration.
The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
Multiple respiratory and vascular mechanisms have recurrently evolved across the vertebrates to alleviate the oxygen diffusion limitations inherent to the morphology of the retina.
The turquoise killifish from ephemeral pools in African savannah combines extremely short lifespan with a standard vertebrate body plan – ideal attributes for a laboratory animal.
Oocyte maturation and ovulation in the sister group of vertebrates, Ciona intestinalis Type A, are triggered by Ci-VP, the Ciona homolog of a typical neruopeptide, vasopressin.
Several key functional features of jawed vertebrate rods are also present in lamprey photoreceptors, indicating that our Cambrian ancestors possessed dim light vision.
The transparent zebrafish reveals the reality of trypanosomes swimming in a vertebrate host, and their adaptations to an extremely heterogenic environment.
