Integrative Single-Cell RNA-Seq and ATAC-Seq Identifies Transcriptional and Epigenetic Blueprint Guiding Osteoclastogenic Trajectory [scATAC-seq]
Osteoclasts (OCs) are multinucleated bone resorbing cells essential for skeletal development and remodeling. In adulthood, OCs originate from the serial fusion of monocytes, yet the transcriptional and epigenetic mechanisms shaping their osteoclastogenic potential at a single cell resolution remain poorly understood. Here, we employed an integrative multi-omics approach, combining single-cell (sc) RNA-seq, scATAC-seq, bulk RNA-seq, and ChIP-seq, to comprehensively define the regulatory landscape of osteoclastogenesis in wild-type (WT) and Irf8 conditional knockout (cKO) mice. Overall design: 10x Genomics scATAC-seq platform comparing WT and Irf8floxCsf1rCre bone marrow cells (Irf8cKO)
