The possible presence of crypt neuron-like cells in chondrichthyes would represent an interesting common feature between bony and cartilaginous fishes.
2
To date, no study has been published on cell renewal in the olfactory epithelium of Chondrichthyes.
3
Much information about this complicated system have been collected in different groups, but nothing is known about Chondrichthyes.
4
There are not very many data in the literature about the morphological and molecular features of the olfactory epithelium of Chondrichthyes.
1
This is the first report of a leptin-like peptide in a cartilaginousfish.
2
The present work shows for the first time OMP's presence in a cartilaginousfish.
3
The table cases deposited in the room with the cartilaginousfish are covered with
4
Although leptin is evolutionarily conserved, no studies have investigated its presence in cartilaginousfish.
5
With the emergence of immunoglobulins in cartilaginousfish, the classical and lytic pathways first appear.
Usage of cartilaginous fishes in anglès
1
Gnathostomes subsequently diverged into two groups, the cartilaginousfishes and the bony vertebrates.
2
The possible presence of crypt neuron-like cells in chondrichthyes would represent an interesting common feature between bony and cartilaginousfishes.
3
We identify a novel ACSBG-like gene lineage which occurs specifically in amphibians, ray finned fishes, coelacanths and cartilaginousfishes named ACSBG3.
4
Lake sturgeon, Acipenser fulvescens, are one of a few species of cartilaginousfishes that complete their life cycle entirely in freshwater.
5
Although this has been observed in other vertebrates, we are the first to show that the pattern is present in cartilaginousfishes.
6
Overall these results suggest that the Ah receptor evolved at least 450 million years ago, prior to the divergence of bony and cartilaginousfishes.
7
Our functional studies suggest that the lack of genes encoding secreted calcium-binding phosphoproteins in cartilaginousfishes explains the absence of bone in their endoskeleton.
8
The presence of this receptor neuron type is well documented in different species of bony fishes but it has never been described in cartilaginousfishes.
