Development of node architecture and emergence of molecular organizer characteristics in the pig embryo

open access: yesDevelopmental Dynamics, Volume 254, Issue 8, Page 916-934, August 2025.
Abstract Background The avian node is the equivalent of the amphibian Spemann's organizer, as indicated by its ability to induce a secondary axis, cellular contribution, and gene expression, whereas the node of the mouse, which displays limited inductive capacities, was suggested to be a part of spatially distributed signaling.

Embryonic Development and a Simple Method for the Evaluation of Developmental Competence in Murray Cod (Maccullochella peelii) Eggs

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 3, June 2025.
ABSTRACT From fertilisation to hatching, we investigated the embryonic development of hatchery‐reared Murray cod eggs incubated at 20°C and determined the developmental stages. Twenty‐eight readily identifiable stages with distinct morphological features were described and illustrated.
