Phenotypic analysis of intra‐epithelial innate lymphoid cells (ILCs) isolated from normal small intestine biopsies. (a) Gating strategy for CD45⁺ lineage⁻ [CD3⁻CD19⁻CD14⁻CD16⁻CD123⁻CD34⁻T cell receptor (TCR)γ/δ⁻TCRα/β⁻] CD103⁺NKp44⁺ and CD103⁺NKp44⁻ intra‐epithelial ILCs. (b) Intracellular expression of indicated transcription factors in CD103⁺ NKp44⁺ (upper panel) and CD103⁺NKp44⁻ (lower panel) ILCs. (c) Expression of indicated cell surface markers in CD103⁺NKp44⁺ cells (upper panel) and CD103⁺NKp44⁻ cells (lower panel) ILCs. Dot‐plots represent one of three independent experiments.
