Table 1_Early nervous system development in the chaetognath Spadella cephaloptera exhibits

An expression-based developmental map tracks conserved developmental genes during early neurogenesis in the chaetognath Spadella cephaloptera. The dataset includes spatiotemporal analyses from gastrulation through early post-embryonic stages, generated by June F. Ordoñez and last updated in May 2026. It provides a comparative reference for assessing conserved and lineage-specific features of early neurogenic patterning across Spiralia.

Use Cases

• Comparative analysis of conserved neurogenic markers based on gene expression patterns for Sce-soxB1-like1, Sce-neuroD, Sce-soxB1, and Sce-soxB2.
• Studying dorsoventral patterning during gastrulation based on reciprocal expression data for Sce-bmp2/4 and Sce-chd.
• Mapping ventral nerve center regionalization based on expression domains of Sce-nk6 and Sce-hb9.
• Analyzing stage-dependent deployment of catecholamine-pathway components based on expression of Sce-th and Sce-dbh.

Strengths

• Provides a detailed molecular description of early neural development for an underrepresented spiralian lineage.
• Combines nuclear-staining–based anatomical staging with spatiotemporal gene expression analysis.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small at 45.8 KB, indicating limited scope.
