(A) Transcriptional regulation of ILC development from the common lymphoid progenitor (CLP) to mature ILC subsets 1, 2, and 3. It is now clear that the CLP transits through a series of intermediates including the early innate lymphoid progenitor (EILP) which in contrast with stages both preceding and following the EILP, downregulate the expression of IL‐7R. (B) Differential regulation of transcription factors and surface receptors is both dynamic and essential for diversification of ILC subsets
