An organizing activity is required for head patterning and cell fate specification in the polychaete annelid Capitella teleta: new insights into cell-cell signaling in Lophotrochozoa.
Many lophotrochozoans (i.e., molluscs, annelids, nemerteans, and polyclad flatworms) display a well-conserved early developmental program called spiral cleavage that contrasts with the high diversityExpand

Characterization of Morphological and Cellular Events Underlying Oral Regeneration in the Sea Anemone, Nematostella vectensis
Cnidarians, the extant sister group to bilateria, are well known for their impressive regenerative capacity. The sea anemone Nematostella vectensis is a well-established system for the study ofExpand

NvERTx: a gene expression database to compare embryogenesis and regeneration in the sea anemone Nematostella vectensis
ABSTRACT For over a century, researchers have been comparing embryogenesis and regeneration hoping that lessons learned from embryonic development will unlock hidden regenerative potential. ThisExpand

Effects of maternal investment on larvae and juveniles of the annelid Capitella teleta determined by experimental reduction of embryo energy content
Experimental manipulations of the energy content of marine invertebrate embryos have been useful in testing key assumptions of life history theory, especially those concerning relationships betweenExpand

A bipolar role of the transcription factor ERG for cnidarian germ layer formation and apical domain patterning.
Germ layer formation and axial patterning are biological processes that are tightly linked during embryonic development of most metazoans. In addition to canonical WNT, it has been proposed thatExpand

MAPK signaling is necessary for neurogenesis in Nematostella vectensis
BackgroundThe nerve net of Nematostella is generated using a conserved cascade of neurogenic transcription factors. For example, NvashA, a homolog of the achaete-scute family of basicExpand

Nodal signaling is required for mesodermal and ventral but not for dorsal fates in the indirect developing hemichordate, Ptychodera flava
ABSTRACT Nodal signaling plays crucial roles in vertebrate developmental processes such as endoderm and mesoderm formation, and axial patterning events along the anteroposterior, dorsoventral andExpand

Regulative capacity for eye formation by first quartet micromeres of the polychaete Capitella teleta.
The stereotypic cleavage pattern shared by spiralian embryos provides unique opportunities to compare mechanisms of cell fate specification of homologous blastomeres, and can give insights into howExpand
