Project description:array-CGH on single blastomeres from day-4 human preimplantation fresh and frozen embryos
| PRJNA171590 | ENA
Project description:In total, 240 single blastomeres from nine top-quality day-4 embryos frozen at day 3 of development and four fresh top-quality day-4 embryos that had one-cell biopsy on day 3 for preimplantation genetic diagnosis (PGD) were collected. Blastomeres' DNA was amplified using SurePlex DNA Amplification System (BlueGnome, Cambridge, UK) . Array-CGH was carried out using 24Sure Cytochip microarrays following the standard protocol (BlueGnome, www.cytochip.com).

Project description:Seventy blastomeres from fourteen frozen-thawed supernumerary human preimplantation embryos were disassociated and genomic was amplified using Multiple Displacement Amplification. BAC array-CGH was performed on the amplified products. BAC array-CGH on single blastomeres amplified by Multiple Displacement Amplification.

Project description:Chromosomal instability (CIN) occurs at high frequency during early in vitro embryogenesis and is known to be associated with early embryonic loss in humans. The chromosomal stability of in vivo-conceived cleavage stage embryos largely remains unknown. Here, we applied haplotyping and copy number profiling to investigate genomic architecture of 171 single bovine blastomeres and to compare the nature and frequency of CIN between in vivo embryos, in vitro embryos produced from ovum pick up with ovarian stimulation (OPU-IVF), and in vitro produced embryos from in vitro matured oocytes without ovarian stimulation (IVM-IVF). Our data shows that CIN is significantly lower in in vivo conceived cleavage stage embryos when compared to in vitro cultured embryos, as genomic stability of single blastomeres in both IVF embryos was severely compromised (P<0.0001)

Project description:Detection of genomic rearrangements from a single cell instead of a population of cells is an emerging research technique with important applications in the study of human fertility, constitutional chromosomal disorders, and tumor progression. Here, we develop a method to improve the detection of single-cell genome-wide copy number variation. Additional information about the blastomeres can be found in GSE11663. At this study, 14 amplified single blastomere DNA samples derived from 3-day-old and 4-day-old human embryos were analyzed by Agilent 244K array CGH. For these single cell Agilent 244K array CGH analyses: non-amplified genomic DNA extracted from the blood of a Klinefelter patient (XXY) was used as a reference sample. As a validation, the corresponding non-amplified genomic DNA samples were analyzed by 250K Nsp I SNP arrays (platform GPL3718 and GSE11663).

Project description:In this study, we extend array CGH technology by making the accurate detection of chromosomal imbalances possible from a single fibroblast and blastomere following Phi29 DNA polymerase amplification. Firstly, array CGH experiments were performed on four different fibroblast cell lines, derived from patients affected by, respectively, trisomy 13, 18, 21, and monosomy X. For each cell line, three single cells were amplified. Following DNA amplification, all cells showed the expected DNA yields (n=12; 1.87 µg plus:minus 0.39). Sex-mismatch array CGH experiments were conducted on amplified DNA samples obtained from each cell. Sex chromosome ploidy levels, as well as all expected autosomal abnormalities were clearly identified. Secondly, we applied single-cell aneuploidy screening for the detection of chromosomal imbalances in preimplantation embryos. DNA from blastomeres from three 7-8 cell-stage embryos was amplified by ï¦29 DNA polymerase. Following DNA amplification, all cells yielded the expected amount of DNA (n=16; 2.45 µg plus:minus 0.41). Chromosomal aneuploidies were accurately detected using a simple and rapid array CGH protocol.
