A relatively small number of signaling pathways govern the early patterning processes of
metazoan development. The architectural changes over time to these signaling pathways offer …

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 …

For over a century, researchers have been comparing embryogenesis and regeneration
hoping that lessons learned from embryonic development will unlock hidden regenerative …

The painted urchin Lytechinus pictus is a sea urchin in the family Toxopneustidae and one
of several sea urchin species that are routinely used as an experimental research organism. …

Cnidarians have become valuable models for understanding many aspects of developmental
biology including the evolution of body plan diversity, novel cell type specification, and …

Most bilaterians exhibit a left–right asymmetric distribution of their internal organs. The sea
urchin larva is notable in this regard since most adult structures are generated from left sided …

Bilateral animals, including humans and most metazoans, are not perfectly symmetrical.
Some internal structures are distributed asymmetrically to the right or left side. A conserved …

For over a century, researchers have been trying to understand the relationship between
embryogenesis and regeneration. A long-standing hypothesis is that biological processes …

Early in animal development many cells are conditionally specified based on observations
that those cells can be directed toward alternate fates. The endomesoderm is so named …
