Single-cell RNA sequencing (scRNA-seq) revealed that rfem.L and rfem.S are expressed in a subset of leukocytes with a macrophage-like gene expression profile.

... and repair has been documented over many decades, recent studies have begun to define a more direct role for specific immune cells in the modulation of tissue repair. One particular cell of the innate immune system, the macrophage, has emerged as a central integrator of the complex molecular processes...

Ablation of individual osteoblasts leads to recruitment of neutrophils and macrophages in varying numbers, depending on the extent of the initial insult...

... expansion of tissue macrophage populations in most organs. Bone marrow cells from Csf1r E631K/+ mice were resistant to CSF1 stimulation in vitro , and Csf1r E631K/+ mice were unresponsive to administration of a CSF1-Fc fusion protein, which expanded tissue macrophage populations in controls. In the brain...

We used this model to test two clinically approved CDK9 inhibitors, AT7519 and flavopiridol, examining their effects on neutrophils, macrophages...

Graham ABSTRACT Macrophages are key regulators of developmental processes, including those involved in mammary gland development. We have previously demonstrated that the atypical chemokine...

...Marine Theret; Remi Mounier; Fabio Rossi ABSTRACT The discovery of new non-canonical (i.e. non-innate immune) functions of macrophages has been a recurring theme over the past 20 years. Indeed, it has emerged that macrophages can influence the development, homeostasis, maintenance and regeneration...

Stallcup Vessel-like networks are quickly formed in subcutaneous FGF2-supplemented Matrigel plugs by two cell types: NG2 + pericytes and F4/80 + macrophages.

The molecular mechanisms regulating this cell migration remain largely unknown. We...

In this paper we identify two such cell types, macrophages and eosinophils, that are recruited around the growing terminal end buds (TEBs) during postnatal development. An important role for leukocytes in mammary gland ductal outgrowth is first...

... as in-situ hybridization for the expression of two new hemopoietic marker genes, draculin and leucocyte-specific plastin , we show that macrophages appear in the embryo at least as early as erythroid cells, but originate from ventro-lateral mesoderm situated at the other end of the embryo, just anterior...

Target cells are signaled to die by macrophages approximately 15 hours after S-phase labeling and this corresponds...
