Investigation and Diagnosis of the Chromosome Variation in Donated/abandoned Blastocyst

February 19, 2025 updated by: Chang Gung Memorial Hospital
Blastocysts derived from patients seeking infertility treatment were generated by in vitro fertilization and embryo culture as previously described, and were evaluated using the Gardner system. As part of the embryo selection process, cells of TE biopsy were collected, and blastocysts were vitrified. The clinical TE biopsies were subjected to whole genome amplification (WGA) with SurePlex reagents (Illumina) followed by NGS-based PGT-A using Illumina's VeriSeq kit (Illumina) on a MiSeq system (Illumina) according to the manufacturer's protocol.

Study Overview

Detailed Description

Collected 200 donate abandonment embryos (well-developed blastocysts) for research under the National Assisted Reproduction Act of Taiwan.

  1. Collected 200 donate abandonment embryos: Five to six days after egg retrieval, well-developed embryos (called blastocysts).
  2. Blastocysts derived from patients seeking infertility treatment were generated.
  3. Embryos biopsies for PGT-A (by use of NGS platforms from our institute) will be used for the validation of our Lab QC embryo.
  4. To standardize the operating procedures
  5. Paper writing.
