The National Institute of General Medical Sciences (NIGMS) awarded a $356,462 Project Grant under the Biomedical Research and Research Training program (CFDA 93.859) to the University of California Irvine to develop new tools for analyzing cell-cell communication using spatial transcriptomic data. The project aims to:

  1. Improve the coverage of genes associated with ligands or receptors not well measured in spatial transcriptomic data using novel optimal transport methods and physically model-based imputation of gene expression at the single-cell level.

  2. Develop a comprehensive cell-cell communication inference method that incorporates prior knowledge and additional data on regulators and co-factors.

  3. Create tools for pattern recognition, systematic comparison, and classification of spatial cell-cell communication networks inferred from spatial transcriptomic data.

The project will also involve a sub-award to North Carolina State University to collaborate on the development of the data integration and cell-cell communication inference methods. The award period is from September 20, 2024 to June 30, 2028.
