Penguin Embryo Gene Expression Microscopy Images for Forelimb Bone Evolution

Original nd2 files for fluorescent in situ microscopy from Figure S7 in a study on penguin flipper evolution. The data show mRNA expression for Acvr1, Rere, and Scx in gentoo penguin ulnae at the HH39 embryonic stage. The dataset was created by Hannah Grunwald and last updated on June 23, 2026.

Use Cases

• Analyze spatial gene expression patterns for Acvr1, Rere, and Scx in embryonic penguin forelimbs.
• Study the cellular basis of bone ridge expansion underlying the evolution of the penguin flipper.
• Compare gene expression profiles associated with the transformation from cylindrical to flattened limb bones.
• Validate or extend findings on the role of specific genes in late embryonic skeletal development.

Strengths

• Contains original microscopy files (nd2 format) for a specific figure in a published study.
• Focuses on a specific embryonic stage (HH39) and species (gentoo penguin).
• Data is associated with a specific research output (Figure S7), providing clear context.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
