Early immune cell development precedes gastrulation in annual killifish

The paper shows that in annual killifish, neutrophils develop before gastrulation, challenging the conserved BMP-driven myeloid lineage model.

Embryo-scale single-cell chemical transcriptomics reveals dependencies between cell types and signaling pathways

The paper uses single-cell RNA-seq to study signaling pathway dependencies in zebrafish pectoral fin development, identifying new cell types and signaling relationships.

Axis formation in annual killifish: Nodal coordinates morphogenesis in absence of Huluwa prepatterning

The paper shows that Nodal coordinates morphogenesis in annual killifish by enabling cell migration, while Huluwa-mediated prepatterning is not required.

The pattern of Nodal morphogen signaling is shaped by co-receptor expression

The paper shows that Nodal morphogen signaling patterns in zebrafish embryos are shaped by co-receptor Oep, which restricts ligand spread and sensitizes cells.
