Recent gene expression data suggest that the region on which the onychophoran antenna is situated corresponds to the anteriormost, apparently appendage-less region of the arthropod head. The fate of the onychophoran antenna (or any appendag...
Functional conservation of Drosophila FTZ-F1 and its mammalian homologs suggests ligand-independent regulation of NR5A family transcriptional activity [0.03%]
节俭型FTZ-F1功能保守性及其在哺乳动物中的同源物表明NR5A家族转录活性的配体非依赖性调控作用

Drosophila Ftz-F1 is an orphan nuclear receptor required for segmentation and metamorphosis. Its mammalian orthologs, SF-1 and LRH-1, function in sexual development and homeostasis, and have been implicated in stem cell pluripotency mainten...

Hemocytes (blood cells) are motile cells that move throughout the extracellular space and that exist in all clades of the animal kingdom. Hemocytes play an important role in shaping the extracellular environment and in the immune response. ...

This report summarizes information discussed at the second Nematostella vectensis research conference, which took place on August 27, 2012 in Boston, MA, USA. The startlet sea anemone Nematostella is emerging as one of leading model organis...
Xenopus radial spoke protein 3 gene is expressed in the multiciliated cells of epidermis and otic vesicles and sequentially in the nephrostomes [0.03%]

How morphological diversity arises is a key question in evolutionary developmental biology. As a long-term approach to address this question, we are developing the water bear Hypsibius dujardini (Phylum Tardigrada) as a model system. We exp...

The study of stem cells in cnidarians has a history spanning hundreds of years, but it has primarily focused on the hydrozoan genus Hydra. While Hydra has a number of self-renewing cell types that act much like stem cells--in particular the...
