The current model of murine innate lymphoid cell (ILC) development holds that
mouse ILCs are derived downstream of the common lymphoid progenitor through
lineage-restricted progenitors. However, corresponding lineage-restricted
progenitors in humans have yet to be discovered. Here we identified a progenitor
population in human secondary lymphoid tissues (SLTs) that expressed the
transcription factor ROR?t and was unique in its ability to generate all known
ILC subsets, including natural killer (NK) cells, but not other leukocyte
populations. In contrast to murine fate-mapping data, which indicate that only
ILC3s express Ror?t, these human progenitor cells as well as human peripheral
blood NK cells and all mature ILC populations expressed ROR?t. Thus, all human
ILCs can be generated through an ROR?t(+) developmental pathway from a common
progenitor in SLTs. These findings help establish the developmental signals and
pathways involved in human ILC development.
