Project description:Natural Killer (NK) cells at different developmental stages (common lymphoid progenitor (CLP), innate lymphoid cell progenitors (ILCP), and refined NK progenitor (NKP)) were collected from Vav1+iCre FOXO1,3flox/flox mice (C57BL/6 background). Total RNA was harvested and sequenced with a strand-specific paired-end RNA-seq protocol.
Project description:Early innate lymphoid progenitors (EILP) have recently been identified in the mouse adult bone marrow as a multipotential progenitor population committed to ILC lineages, but their relationship with other described ILC progenitors is still unclear. In this study, we examine the progenitor-successor relationships between EILP, IL-7R+ common lymphoid progenitors (ALP), and ILC precursors (ILCp). Bioinformatic, phenotypical, functional, and genetic approaches collectively establish EILP as an intermediate progenitor between ALP and ILCp. Our work additionally provides new candidate regulators of ILC development and clearly defines the stage of requirement of transcription factors key for early ILC development.
Project description:Helper innate lymphoid cells (ILC) play important functions in immunity and tissue homeostasis, but their development remains poorly understood. In this study, we identified NFIL3 as the earliest known requirement during ILC development. Forced expression of NFIL3 in mouse lymphoid progenitors in vitro triggered the staged expression of downstream transcription factors including Tcf7, Gata3, Zbtb16 and Id2 that are implicated in ILC development. Thus, NFIL3 resides at the apex of a hierarchy of transcription factors important for innate lymphocyte development, and is necessary and sufficient to impose the innate lymphoid cell fate.

Project description:We identified a new type of bone marrow progenitors termed early innate lymphoid cell progenitor (EILP) using TCF-1 GFP reporter mice. We compared the transcriptomes of early innate lymphoid cell progenitors (EILP) with other early progenitors, including HSC, LMPP, CMP, CLP, ETP and DN3.
