Identification and characterization of a twist ortholog in the polychaete annelid Platynereis dumerilii reveals mesodermal expression of Pdu...
We identified a twist ortholog in the polychaete annelid Platynereis dumerilii and analyze its expression during larval development, postlarval growth up to the adult stage, and caudal regeneration after amputation of posterior segments. At late larval stages, Pdu-twist is expressed in the mesoderma...
The fate of the onychophoran antenna.
Our data on early axogenesis in anostracan crustaceans show that even in the earliest embryos, before the antennula and antennal nerves are developed, the circumoral anlagen of the brain display very prominent nerves which run into the frontal filament organ (also known as the cavity receptor organ)...
The stem cell system in demosponges: suggested involvement of two types of cells: archeocytes (active stem cells) and choanocytes (food-entr...
Major questions about stem cell systems include what type(s) of stem cells are involved (unipotent/totipotent/pluripotent/multipotent stem cells) and how the self-renewal and differentiation of stem cells are regulated. Sponges, the sister group of all other animals and probably the earliest branchi...
Stem cell dynamics in Cnidaria: are there unifying principles?
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 interstitial cell line-finding cellular homologues outside o...
Histological evidence: housekeeping genes beta-actin and GAPDH are of limited value for normalization of gene expression.
We compared the histological expression profile of two commonly used housekeeping genes, GAPDH and beta-actin, in the developing chicken embryo by using section and whole mount in situ hybridization supplemented by RT-PCR. Our results show that neither GAPDH mRNA nor beta-actin mRNA is expressed in...
Sexually dimorphic expression of foxl2 during gametogenesis in scallop Chlamys farreri, conserved with vertebrates.
We cloned a full-length cDNA sequence of foxl2 from the scallop Chlamys farreri, an important commercial mollusk in China. The cDNA sequence of Cf-foxl2 (C. farreri foxl2) has 1,824 bp with an open reading frame of 1,107 bp encoding 369 amino acid residues containing the conserved domain forkhead...
Oenocyte development in the red flour beetle Tribolium castaneum.
We compare and contrast the specification and development of larval oenocytes between Drosophila and the red flour beetle, Tribolium castaneum. First, we identify several useful reagents to label larval oenocytes, including both a Tribolium GFP enhancer trap line and a simple flurophore-conjugated s...
Morphogenesis of Pseudopallene sp. (Pycnogonida, Callipallenidae) I: embryonic development.
Embryonic development of Pycnogonida (sea spiders) is poorly understood in comparison to other euarthropod lineages with well-established model organisms. However, given that pycnogonids potentially represent the sister group to chelicerates or even to all other euarthropods, their d...
BMP signals and the transcriptional repressor BLIMP1 during germline segregation in the mammalian embryo.
We analyzed temporal and spatial expression patterns of the transcriptional repressor BLIMP1 (also known as PRDM1) and the signaling molecules BMP2 and BMP4 in perigastrulation and early neurulation embryos of the rabbit using whole-mount in situ hybridization and high-resolution light microscopy. B...
The paleoAP3-type gene CpAP3, an ancestral B-class gene from the basal angiosperm Chimonanthus praecox, can affect stamen and petal developm...
We seek to determine the molecular features and expression patterns of the C. praecox paleoAP3-type gene CpAP3 and examine its potential role in regulating floral development via ectopic expression in Arabidopsis thaliana and Petunia hybrida. The expression of CpAP3 is tissue-specific, with the high...
