MeSH Description
The relatively long-lived phagocytic cell of mammalian tissues that are derived from blood MONOCYTES. Main types are PERITONEAL MACROPHAGES; ALVEOLAR MACROPHAGES; HISTIOCYTES; KUPFFER CELLS of the liver; and OSTEOCLASTS. They may further differentiate within chronic inflammatory lesions to EPITHELIOID CELLS or may fuse to form FOREIGN BODY GIANT CELLS or LANGHANS GIANT CELLS.

RNA-seq: RNA was extracted from FACS sorted cells ext using the QIAGEN RNEasy plus mini-kit. ChIP-seq: Cells were lysed and chromatin was fragmented with Micrococcal nuclease (MNase) and incubuated with 2 mg of anti-H3K27ac (39133, Active Motif) for immunoprecipitation RNA-seq: Poly-A selected mRNA was then converted to Illumina sequencing ready libraries using NEB kit following the user-guide. cDNA libraries were pooled and sequenced at the Institut Cochin, Paris with one run of Illumina NextSeq 500 ChIP-seq: Libraries were prepared as follows. Briefly, DNA was end-repaired using a combination of T4 DNA polymerase, E. coli DNA Pol I large fragment (Klenow polymerase) and T4 polynucleotide kinase. The blunt, phosphorylated ends were treated with Klenow fragment (32 to 52 exo minus) and dATP to yield a protruding 3- 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3' end. After adapter ligation DNA was PCR amplified with Illumina primers for 15 cycles and library fragments of ~300 bp (insert plus adaptor and PCR primer sequences) were purified by double-sided SPRI size selection . The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were send to a sequencing platform core facility and sequenced on a Next-seq 500 (Illumina).
