Spatial TranscriptOmics DataBase (STOmicsDB) is a comprehensive portal integrating spatiotemporal omics literature, tools, and data. It consists of the following sections:
We used Scanpy (version 1.8.1) with default parameters to analyze curated datasets. Key steps include:
Example: For a mouse brain dataset, PCA and UMAP identified distinct cell clusters, while spatialDE highlighted spatially restricted genes.
Download Links: All data and analysis results are available in the Data and Analysis results tabs.
STOmicsDB uses Cirrocumulus for interactive visualization. Key features include:
Example Use Case: Visualize the expression of a specific gene (e.g., Sox2) across tissue sections.
For detailed documentation, visit Cirrocumulus Documentation.
Explore general statistics, heatmaps, cluster markers, volcano plots, GO/KEGG enrichment, cell-cell interactions, and spatially-specific modules.
Example: Use volcano plots to identify differentially expressed genes between clusters.
STOmicsDB provides a robust data archiving service for securely storing and sharing spatial omics data. This service supports sequencing data (e.g., FASTQ, BAM) and associated metadata, ensuring compliance with data standards.
Search datasets using keywords and filters (e.g., species, tissue details, technologies).
Example: Search for "mouse liver regeneration" datasets.
Search publications using keywords and filters (e.g., research areas, species).
Example: Filter publications by "zebrafish embryogenesis."
STOmicsDB offers customized database services. Current databases include:
Example Use Case: Use ATRISTA to explore axolotl regeneration datasets.
SingleR
Annotate cell types by uploading single-cell RNA sequencing data. Outputs include spatial feature plots.
Example: Annotate immune cells in a tumor microenvironment dataset.
Gene Search
Search for genes to view spatial maps across dataset sections.
Example: Search "TP53" in human datasets to explore its spatial expression.
Compare
Compare spatial gene expression between two datasets.
Example: Compare liver regeneration datasets from mouse and human.
Stereomap
Visualize ultra-high resolution datasets with over one million cells.
Example: Explore high-resolution spatial data from a mouse brain dataset.
STOmicsDB provides two core services designed to meet your data submission needs:
