While the genes involved in craniofacial development are highly conserved between the fat-tailed dunnart and mouse, their cis-regulatory elements show significant divergence and appear to reflect species-specific developmental processes.
A genetic tracing study demonstrates that neural progenitor lineage dominance may not be maintained in differentiated progeny, underscoring the critical need for region-specific markers to validate pluripotent stem cell–derived products.

Integrated proteomic and single-cell transcriptomic analyses define the Nematostella vectensis matrisome and reveal conserved extracellular matrix functions driving life cycle transitions in this non-bilaterian model.
Mouse sperm are unable to bind the zebrafish chorion, yet a subset of hyperactivated sperm can enter and cross the micropyle, suggesting a conserved mechanism of gamete interaction across species.
