From: Generation of viable blastocysts from discarded human cleavage embryos
Preimplantation genetic testing for aneuploidy (PGT-A) of biopsied blastocysts obtained from surplus embryos applying FISH technique. The images showed normal nuclei: a stained with DAPI; b for chromosome X (green), chromosome Y (red), and chromosome 18 (blue) in first round; and c a blastocyst with mosaicism for chromosome 13 (green), and chromosome 18 (blue) using specific probes (Cytocell, OGT Company, Cambridge, UK)
