From: Mosaic pregnancy after transfer of a “euploid” blastocyst screened by DNA microarray
Morphology and PGS chart of a blastocyst transferred. A) Blastocyst after warming and B) same blastocyst after 2 hrs of culture. C) PGS chart of the sample biopsied from the blastocyst, showing 46, XX. D) Diagram of the blastocyst based on the PGS and prenatal cytogenetic tests, showing that the blastocyst has euploid inner cell mass, partial euploid trophectoderm (TE) and partial aneuploid (47, XX, +21) TE. Yellow arrows indicate the inner cell mass (ICM), and red arrows indicate the TE.
