Fig. 3

A Clustered heatmap showing differentially expressed eccDNAs in paired primary tissues and metastatic tissues of four HGSOC patients. Red, up-regulation; Blue, down-regulation. B The SEM images of extracted eccDNAs in HGSOC tissues and ovarian cancer cell lines SKOV3, A2780 and OVCAR3. Scale bar, 1 μm. C The TEM images of eccDNAs in HGSOC tissues, SKOV3, A2780, and OVCAR3 cells. Scale bars, 2 μm and 1 μm. All imaging experiments were repeated at least three times, with similar results.
