The Botryllus schlosseri genome yields insights into the evolution of hematopoiesis.

The protein PTRN-1 anchors microtubules in neuronal branches to promote proper neuron morphology and function in Caenorhabditis elegans.

Stem cell migration underlies head regeneration in the cnidarian (jellies and their kin) Hydractinia, but the regeneration of other body parts is based on the gradual transformation of one tissue type into another.

A gene regulatory network model provides a simplified explanation of the molecular interactions that orchestrate muscle development in the sea urchin embryo.

The first malacostracan genome sequence will establish the genetically tractable Parhyale hawaiensis as a model organism in this key animal group.

Serial-section EM analysis uncovers the CNS connectome of a Ciona larva, the second of any entire nervous system, and exposes left-right asymmetries in its synaptic circuits.

Molecular profiling of annelid myocytes reveals that the last common protostome-deuterostome ancestor already possessed a dual musculature, with visceral smooth muscles ensuring digestion and somatic striated muscles ensuring locomotion.

Unexpected findings from the immune system of sea urchin larvae potentially provide insights into immune signaling in ancestral lifeforms.

Expression of two highly regulated subfamilies of the complex multigene family encoding IL-17 cytokines in the purple sea urchin are sequentially activated in a larval gut-associated inflammation model and modulate downstream gene expression in the gut epithelium.

Connectomic reconstruction combined with activity imaging uncovered a rhythmically active neuronal circuit for the coordination of ciliary activity across the whole body of a marine larva.
