Fluorescence in situ hybridization. Interphase FISH overview using probes specific to human chromosome 1 (green) and chromosome 15 (red) alpha-satellite sequences. Sections were counterstained by DAPI (blue) showing nuclei of both human and chicken cells. A: FISH signals were detected in human cells only, chicken erythrocytes showed no signals (indicated by white arrows). B: Human cells are well demarcated from CAM cells (dashed white line) and attracted numerous blood vessels and erythrocytes (white arrows).
