Objective:

To develop a computational framework for spatial RNA velocity analysis that infers transcriptional dynamics from high-resolution spatial transcriptomics in melanoma.

Approach:

Key Findings:

• Cluster-specific dynamic genes were identified that are significantly associated with patient prognosis.
• Dynamic genes formed protein-protein interaction networks enriched for immune-related pathways.
• Distinct spatially patterned progressions were observed within malignant cells and T cell trajectories.

Interpretation:

The study provides a computational strategy to decode spatiotemporal dynamics from spatial transcriptomic data, linking cellular state, spatial context, and clinical phenotype.

Limitations:

• The proxy-based approach relies on assumptions regarding RNA processing and localization.
• Careful interpretation is required when inferring transcriptional dynamics from spatial data.

Conclusion:

The study offers an analytical approach to connect tissue architecture, cellular dynamics, and clinical outcomes in melanoma.
