Understanding transcriptional identity in Innate Lymphoid Cells (ILC)
In order to determine the dependency of mature tissue-resident ILCs on combinations of synergistic and antagonising Transcription Factors (TFs), we generated mice with conditional deletions of RORc, RORa and Tbx21 driven from the Id2 allele, utilizing a tamoxifen inducible Cre-recombinase in combination with a tdRFP allele to report Cre-excision (Id2creERT2 x ROSAtdRFP). RFP+ small intestinal ILCs were sorted from the lamina propria digests (gated as CD45+, Lineage negative, CD90+ CD127+, tdRFP+ - see manuscript for full methodological details), from control mice or mice containing loxP flanked alleles for RORc, RORc and RORa or RORc and Tbx21. Four samples of sort-purified ILCs were then subjected to 10X single cell sequencing; - Id2creERT2 - Id2idRORc - Id2idRORc/RORa - Id2idRORc/Tbx21
