Project description:Macrophages are pivotal effectors of host immunity and regulators of tissue homeostasis. Understanding of human macrophage biology has been hampered by the lack of reliable and scalable models for cellular and genetic studies. Human iPSC-derived monocytes and macrophages, as an unlimited source of subject genotype-specific cells, will undoubtedly play an important role in advancing our understanding of the role of macrophage biology and implication in human diseases. Here, we present RNA-Seq data of hiPSC-derived monocytes and GM-CSF or M-CSF macrophages generated by a fully optimized differentiation protocol as well as primary myeloid cells.

Zameel Cader, Richard Wade-Martins, William S. James, Sally A. Cowley The aim of the experiment was to compare the gene expression profiles from human iPSC-derived embryonic macrophages (both precursors, mature, and cells cultured in 'microglia medium'), with iPSC-macrophages differentiated to microglia by co-culture with iPSC-derived cortical neurons. They were also compared to human blood-derived monocytes and to human primary fetal microglia.
Project description:As supplies of monocytes, macrophages and dendritic cells from human sources can be scarce or prone to donor variation we established an efficient method to generate induced pluripotent stem cell derived monocytes that in turn could be differentiated into both macrophages and dendritic cells. We used RNA sequencing to profile these from multiple differentiation runs (n=3) and multiple monocyte harvests (n=3-4) and compared them to their blood derived counterparts, blood derived monocyte, monocyte derived macrophages and moncyte derived dendritic cells (from 3 donors).

Project description:Tissue-resident macrophages such as microglia, Kupffer and Langerhans cells derive from Myb-independent yolk sac (YS) progenitors generated before the emergence of hematopoietic stem cells (HSCs). Myb-independent YS-derived resident macrophages self-renew locally, independently of circulating monocytes and HSCs. In contrast, adult blood monocytes as well as infiltrating, gut and dermal macrophages derive from Myb-dependent HSCs. These findings are derived from the mouse, using gene knock-outs and lineage tracing, but their applicability to human development has not been formally demonstrated. Here we use human induced pluripotent stem cells (iPSCs) as a tool to model human hematopoietic development. By using a CRISPR-Cas9 knock-out strategy we show that human iPSC-derived monocytes/macrophages develop in a MYB-independent, RUNX1 and SPI1 (PU.1)-dependent fashion. This result makes human iPSC-derived macrophages developmentally related to and a good model for MYB-independent tissue-resident macrophages such as alveolar and kidney macrophages, microglia, Kupffer and Langerhans cells.
