METHOD FOR TROPHOBLAST CELLS BIOPSY AT MULTIPLICITY OF CELLS THAT DO NOT PARTICIPATE IN COMPACTION AT BLASTOCYST STAGE FOR HUMAN EMBRYOS PREIMPLANTATION GENETIC SCREENING PROGRAMMES

摘要

FIELD: medicine.;SUBSTANCE: for trophoblast cells biopsy in human embryos preimplantation genetic screening programs, blastocysts pellucid zone is completely removed in the presence of multiple cells that do not participate in compaction. Trophoblast cells are freed, biopsy is performed not including the cells that are not involved in compaction into the material transferred to genetic diagnosis.;EFFECT: method allows to obtain biopsy material of good quality due to the complete removal of the pellucid zone.;2 ex
