Innate lymphoid cells (ILCs) have ample roles in tissue homeostasis, inflammation and repair. ILCs are generated early during ontogeny and persist predominantly as tissue-resident cells. How ILCs are maintained and renewed remains unclear. Here, we generated a single cell atlas of lung ILC2s and found that Il18r1+ ILCs comprise circulating and tissue-resident ILC progenitors (ILCP) and effector-cells with heterogenous expression of Tcf7, Zbtb16 and CD103. We revealed a continuous differentiation trajectory and validated the potential of Il18r1+ ILCPs to generate ILC2s. Upon helminth infection, recruited and BM-derived cells generated the entire spectrum of ILC2s in parabiotic and shield chimeric mice, consistent with their potential role in the renewal of tissue ILC2s. Our work identifies local ILCPs and highlights their in situ differentiation and tissue adaptation as a mechanism of ILC maintenance and phenotypic diversification. Our results suggest that local tissue niches, rather than progenitor origin, or the developmental window during ontogeny, dominantly imprint ILC phenotypes in adult tissues.
