Nucleus hybridization of probes with target chromosomes of one blastomere biopsied from cleavage-stage embryo for PGT-A applying FISH technique. The image showed a female normal nucleus for chromosome X (green), chromosome Y (red), and chromosome 18 (blue) in first round as well as chromosome 13 (green) and chromosome 21 (red) in the second round using specific probes (Cytocell, OGT Company, Cambridge, UK) in each round
