Spatially restricted bmp16 in an extra-embryonic syncytium promotes dorsoventral patterning

The paper identifies bmp16 expression in the zebrafish yolk syncytial layer and shows its role in dorsoventral patterning through functional perturbations.

BMP signaling during gastrulation pre-patterns the dorsal spinal cord

This study shows that BMP signaling during gastrulation pre-patterns dorsal spinal cord fates, challenging the classic model that attributes this to roofplate-derived BMP.

Dynamic polyadenylation safeguards developmental trajectories during paused embryogenesis

The paper shows that polyadenylation safeguards developmental trajectories during paused embryogenesis in zebrafish by stabilizing mRNA targets and maintaining axial patterning.

Two parallel lineage-committed progenitors contribute to the developing brain

The paper identifies two lineage-committed progenitors in the developing brain that generate forebrain/midbrain and hindbrain regions, and demonstrates their distinct chromatin landscapes and differentiation potential.
