(Submitter supplied) The impact of cell origin on human lung macrophage identity and function remains unknown. In this study we characterized human alveolar macrophages of fetal versus adult origin. We used microarray to define the gene signatures of human alveolar macrophages derived from CD116+CD64+ fetal monocytes, CD116+CD64- fetal precursors, and CD34+ HSPCs in MISTRG humanized mice.

(Submitter supplied) Despite their importance in lung health and disease, it remains unknown how human alveolar macrophages develop early in life. In this study we identified the fetal progenitor of human alveolar macrophages. We used microarray to define the gene signatures of human CD14+ blood monocytes (adult AM precursors), CD116+CD64+ fetal liver monocytes, and CD116+CD64- fetal AM precursors.

(Submitter supplied) Tissue-resident macrophages comprise heterogeneous populations with unique functions and distinct gene expression signatures. While it has been established that they mostly originate from embryonic progenitors, the signals inducing a characteristic tissue-specific differentiation program remain unknown. Here we identify PPARγ as the crucial transcription factor determining perinatal alveolar macrophage (AM) development and identity. more...

(Submitter supplied) We studied alveolar macrophage (AM) development after single and competitive transplantation of different precursors from YS, fetal liver, and lung into neonatal Csf2ra-/- mice, which lack endogenous AM. Fetal monocytes, promoted by Myb, outcompeted primitive MΦ (pMΦ) in empty AM niches and preferentially developed to mature AM, which is associated with enhanced mitochondrial respiratory and glycolytic capacity and repression of the transcription factors c-Maf and MafB. more...

(Submitter supplied) Tissue-resident macrophages can derive from yolk sac macrophages, fetal liver monocytes or adult bone marrow monocytes. Whether these precursors can give rise to transcriptionally identical alveolar macrophages is unknown. Here, we transferred traceable yolk sac macrophages, fetal liver monocytes, adult bone marrow monocytes or adult alveolar macrophages as a control, into the empty alveolar macrophage niche of neonatal Csf2rb-/- mice. more...

(Submitter supplied) Tissue-resident macrophage-based immune therapies have been proposed for various diseases. However, generation of sufficient numbers that possess tissue-specific functions remains a major handicap. Here, we show that fetal liver monocytes cultured with GM-CSF (CSF2-cFLiMo) rapidly differentiate into a long-lived, homogeneous alveolar macrophage (AM)-like population in vitro. CSF2-cFLiMo remained the capacity to develop into bona fide AM upon transfer into Csf2ra-/- neonates and prevented development of alveolar proteinosis and accumulation of apoptotic cells for at least 1 year in vivo. more...

(Submitter supplied) Although classified as hematopoietic cells, tissue-resident macrophages are selfrenewing and maintained independently of adult hematopoiesis. While most macrophages originate from embryonic precursors that seed tissues prior to birth, their exact origin is unknown. Using an in utero macrophage depletion strategy and fatemapping of yolk sac (YS) and fetal liver (FL) hematopoiesis, we found that YS macrophages are the main precursors of microglia, while most other macrophages derive from fetal monocytes. more...

(Submitter supplied) GM-CSF receptor-β deficient (Csf2rb–/– or KO) mice develop a lung disease identical to hereditary pulmonary alveolar proteinosis (hPAP) in humans with recessive CSF2RA or CSF2RB mutations that impair GM-CSF receptor function. We performed pulmonary macrophage transplantation (PMT) of bone marrow derived macrophages (BMDMs) without myeloablation in Csf2rb–/–mice. BMDMs were administered by endotracheal instillation into 2 month-old Csf2rb–/– mice. more...

(Submitter supplied) Converging evidence indicates that extra-embryonic yolk sac is the source of both macrophages and endothelial cells in adult mouse tissues. Prevailing views are that these embryonically derived cells are maintained after birth by proliferative self-renewal in their differentiated states. Here we identify clonogenic endothelial-macrophage (EndoMac) progenitor cells in the adventitia of embryonic and postnatal mouse aorta, that are independent of Flt3-mediated bone marrow hematopoiesis and derive from an early embryonic CX3CR1+ and CSF1R+ source. more...

(Submitter supplied) Alveolar macrophages (AMs) are tissue resident cells in the lungs derived from the fetal liver that maintain lung homeostasis and respond to inhaled stimuli. While the importance of AMs is undisputed, they remain refractory to standard experimental approaches and high-throughput functional genetics as they are challenging to isolate and rapidly lose AM properties in standard culture. This limitation hinders our understanding of key regulatory mechanisms that control AM maintenance and function. more...

(Submitter supplied) Single-cell genomic technologies hold great potential to advance our understanding of lung development and disease. A major limitation lies in accessing intact cells from primary lung tissues for profiling human airway health. Sampling methods such as endotracheal aspiration that are compatible with clinical interventions could enable longitudinal studies, the enrollment of large cohorts, and the development of novel diagnostics. more...
