Summary
HemaScope is a new bioinformatics toolkit for analyzing single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) data from hematopoietic cells. It offers user-friendly tools for cell atlas construction, heterogeneity exploration, and microenvironment analysis.
Area of Science:
- Computational Biology
- Genomics
- Hematology
Background:
- Single-cell RNA sequencing (scRNA-seq) and spatial transcriptomics (ST) are crucial for understanding hematopoietic cell heterogeneity and spatial organization.
- Existing tools often lack comprehensive integration for both scRNA-seq and ST data, particularly for specialized hematopoietic cell analysis.
Purpose of the Study:
- To develop HemaScope, a specialized, user-friendly bioinformatics toolkit for integrated analysis of scRNA-seq and ST data in hematopoietic cells.
- To provide modular functionalities for quality control, cell atlas construction, heterogeneity and spatial analysis, and microenvironment characterization.
Main Methods:
- Development of a modular bioinformatics toolkit, HemaScope, with functionalities for scRNA-seq and ST data analysis.
- Integration of hematopoietic cell-specific features like lineage evaluation and cell cycle prediction.
- Deployment in multiple user-friendly formats: R package, web server, Docker image, and graphical interface.
Main Results:
- HemaScope successfully constructed a human bone marrow cell atlas and analyzed age-related changes.
- The toolkit identified acute myeloid leukemia cells in mice and characterized microenvironments in lymphoma subtypes.
- Demonstrated elucidation of tumor boundaries and spatial relationships within hematopoietic tissues.
Conclusions:
- HemaScope provides a powerful and accessible solution for analyzing complex scRNA-seq and ST data in hematopoiesis research.
- The toolkit facilitates deeper insights into hematopoietic cell heterogeneity, spatial organization, and disease mechanisms.
- HemaScope enhances user experience through diverse deployment options and specialized features for hematopoietic cell analysis.
