Brefeldin A and monensin inhibit the D quadrant organizer in the polychaete annelids Arctonoe vittata and Serpula columbiana
TLDR
The results suggest that the D quadrant organizer is functionally conserved in equal‐cleaving polychaetes, but that details of its specification, induction, and patterning have diverged relative to other spiral-cleaving phyla. Expand
Specification of first quartet micromeres in Ilyanassa involves inherited factors and position with respect to the inducing D macromere.

TLDR
Cell transplantation experiments demonstrate that the proximity of a first quartet micromere relative to the inducing D macromere is important for determining whether or not it will go on to develop an eye. Expand
The development of early pioneer neurons in the annelid Malacoceros fuliginosus
TLDR
It is suggested that closer examination of the first pioneer neurons will be valuable in better understanding of nervous system development in spirally cleaving animals, to determine the potential role of cell-intrinsic properties in neuronal specification and to resolve the evolution of nervous systems. Expand
Peculiarities of isolated blastomere development of the polyhaete Alitta virens
TLDR
For the first time, the development of the polychaete Alitta virens blastomeres isolated at different stages is shown and the results indicate the inability of A. virens partial embryos of regulation to form a whole normal larva and a high degree of autonomous determination of trochoblast cells.

Dpp/BMP2-4 Mediates Signaling from the D-Quadrant Organizer in a Spiralian Embryo
TLDR
The results indicate that Dpp/BMP2-4 signaling is a key part of the spiralian organizer and suggest similarity with other metazoan organizers, but highlight the significant variation across animals in effects of the pathway on particular cell types and tissues. Expand
Mollusc models I. The snail Ilyanassa.
TLDR
New insight into early cell lineage specification in Ilyanassa is highlighted, and emerging evidence suggests wider roles for short-range intercellular signaling. Expand
Early embryogenesis of potential bilaterian animals with polar lobe formation from the Ediacaran Weng'an Biota, South China
TLDR
Results provide more convincing evidence for animal affinities among the Doushantuo embryos, and indicate that polar lobes, which break the symmetrical distribution of morphogenetic determinants in cytoplasm during the early developmental stages of living bilaterian embryos, are a conserved device that occurred already during animal embryogenesis even in the Precambrian. Expand
Functional role for MAP kinase signaling in cell lineage and dorsoventral axis specification in the basal gastropod Testudinalia testudinalis (Patellogastropoda, Mollusca)
TLDR
The data indicate the existence of various molecular mechanisms of determination of the secondary body axis among the animals from the group Spiralia and the influence of the U0126 inhibitor of the MAP kinase pathway on the development of Testudinalia. Expand
Secondary embryonic axis formation by transplantation of D quadrant micromeres in an oligochaete annelid
TLDR
It is shown that D quadrant micromeres of the oligochaete annelid Tubifex tubifex are essential for embryonic axis formation, but they lack the ability to induce neuroectodermal tissues, a characteristic common to chordate primary embryonic organizers. Expand
The Slipper Snail, Crepidula: An Emerging Lophotrochozoan Model System
TLDR
A review of the current state of knowledge of Crepidula life histories and development together with some detailed experimental methods are brought together to encourage further use of this system in various fields of investigation. Expand
