Transcriptome analysis of OBs, OCs, and OB-derived EVs.a Representative flow cytometric analysis of cells in scales at 1 day post-fracture (dpf) from a trap:GFP; osterix:mCherry double-transgenic animal. Gated regions in the left panel indicate the Hoechst 33342high (Hoehigh) cell fraction and osterix:mCherry+ Hoelow fraction (“EV”). Cells in the Hoehigh fraction are displayed in the right panel to further divide into three populations, trap:GFP−osterix:mCherry+ (“mCh+”), trap:GFPlowosterix:mCherry+ (“GFPlow”), and trap:GFPhigh (“GFPhigh”). b Principal component analysis (PCA) based on the read per million (RPM) of each sample. c, d Hierarchical clustering of selected OC-related c and OB-related genes d in the mCh+, GFPlow, GFPhigh, and EV fraction in the fractured scale. e Gene ontology enrichment analysis of highly expressed genes in the mCh+, GFPlow, GFPhigh, and EV fraction. Experiments were performed once with two biological replicates.
