Human Cell Atlas & single-cell biology of organoids

Single-cell technologies provide a fundamentally new perspective for understanding biology, with profound potential to drive therapeutic advances. They enable us to revisit human anatomy and physiology with unprecedented molecular resolution. Moreover, these assays help uncover the hidden cellular heterogeneity that is present both in primary tissues and in complex in vitro disease models, thereby contributing to robust, reproducible biomedical research and clinical translation.

We are using single-cell technologies in a range of applications, organs, and diseases. Most notably, we have initiated an Organoid Cell Atlas initiative, as a ‘Biological Network’ within the Human Cell Atlas (HCA), and we coordinate the HCA|Organoid consortium aimed at establishing comprehensive single-cell profiles of brain and colon organoids (funded by the European Union).

Organoids recapitulate important aspects of human biology in the lab, thereby allowing us to perform highly interventional studies that would otherwise be impossible in human. Using high-throughput functional assays such as CRISPR screens with single-cell sequencing readout (with our CROP-seq and scifi-RNA-seq methods) and cell-cell interaction profiling in co-cultures of organoids and immune cells, we study human biology and human diseases in an exciting new way.
