Abstract
Despite the key role of primary and secondary lymphoid organ stroma in immunity, our understanding of the heterogeneity and ontogeny of these cells remains limited. Here, we identify a functionally distinct subset of BP3(-)PDPN(+)PDGFRβ(+)/α(+)CD34(+) stromal adventitial cells in both lymph nodes (LNs) and thymus that is located within the vascular niche surrounding PDPN(-)PDGFRβ(+)/α(-)Esam-1(+)ITGA7(+) pericytes. CD34(+) adventitial cells developed in late embryonic thymus and in postnatal LNs and in the thymus originated, along with pericytes, from a common anlage-seeding progenitor population. Using lymphoid organ re-aggregate grafts, we demonstrate that adult CD34(+) adventitial cells are capable of differentiating into multiple... (More)

CD34(+) adventitial cells developed in late embryonic thymus and in postnatal LNs and in the thymus originated, along with pericytes, from a common anlage-seeding progenitor population. Using lymphoid organ re-aggregate grafts, we demonstrate that adult CD34(+) adventitial cells are capable of differentiating into multiple lymphoid stroma-like subsets including pericyte-, FRC-, MRC-, and FDC-like cells, the development of which was lymphoid environment-dependent. These findings extend the current understanding of lymphoid mesenchymal cell heterogeneity and highlight a role of the CD34(+) adventitia as a potential ubiquitous source of lymphoid stromal precursors in postnatal tissues.
