The Single Cell Genomics Team focuses on the systematic integration of genomic data from individual cells to elucidate causalities underlying phenotype formation.

The mission of the team is the implementation of single-cell sequencing technologies and their application in a research and translational context. We established single-cell RNA sequencing processes for MARS-seq and SMART-seq and high-throughput protocols in microfluidic systems. Newly developed computational pipelines include methods to deconvolute tissue composition, identify cell type markers and track transcriptional dynamics. We are joining computational, statistical and biological knowledge in order to establish and apply best practices in single-cell research. The team combines collaborative research, development activities and follows an independent research line on translational cancer research.

We critically enlarged the scope of single-cell methods by implementing cryopreservation for sample transfer and archiving. A systematic comparison of different protocols pointed to large differences in sensitivity of molecule capture, with a high degree of accuracy across the methods. We applied single-cell RNA sequencing for cellular phenotyping, among others, during development, tumor evolution and aging. To be also able to characterize the single cell genome and epigenome, we are implementing new approaches for the identification of somatic alterations or open chromatin states.

Our research expertise is complemented with CNAG-CRG’s large next-generation sequencing capacity coupled with high performance supercomputer. We are also equipped with a microfluidic devices, an automated liquid handling platform and we collaborate with experienced FACS facilities. Our experience in single cell genomics is unique in Spain and suits research on virtual every species, tissue or disease context. We welcome partnerships and collaborations across all areas of life sciences as well as computational projects to tackle the analytic complexity of single cells. We are member of the Human Cell Atlas Project.
