Title Single Cell RNA sequencing of mouse CD11b+, Gr1+ cells from the spleen from FVB/n and PYMT mice
Organism Mus musculus
Experiment type Expression profiling by high throughput sequencing
Summary Myeloid-derived suppressor cells (MDSCs) are innate immune cells that acquire the capacity to suppress adaptive immune responses during cancer. It remains elusive how MDSCs differ from their normal myeloid counterparts, which limits our ability to specifically detect and therapeutically target MDSCs during cancer. Here, we used single-cell RNAseq to compare MDSC-containing splenic myeloid cells from breast tumor-bearing mice to wildtype controls. Our computational analysis of 14,646 single-cell transcriptomes reveals that MDSCs emerge through a previously unrealized aberrant neutrophil maturation trajectory in the spleen giving rise to a unique chemokine-responsive, immunosuppressive cell state that strongly differs from normal myeloid cells. We establish the first MDSC-specific gene signature and identify novel surface markers for improved detection and enrichment of MDSCs in murine and human samples. Our study provides a single-cell transcriptional map defining the development of MDSCs, which will ultimately enable us to specifically target these cells in cancer patients.
Overall design Droplet Based Single Cell RNA sequencing libraries were generated for 5 pooled FVB/n mouse spleens and 3 pooled PYMT mouse spleens using the 10x Genomics Chromium Platform and sequenced on the Illumina HighSeq 4000
