Abnormal chromosomal arrangements in human oocytes [PDF]
, 2017 Ninety-one human oocytes, lacking signs of fertilization 50 h after insemination in vitro, were investigated cytogenetically to assess the frequency and type of chromosomal abnormalities. Chromosome spreading permitted adequate karyotyping in 55 oocytes.

Derivation of Haploid Trophoblast Stem Cells via Conversion In Vitro
iScience, 2019 Summary: Owing to their single genome, haploid cells are powerful to uncover unknown genes by performing genetic screening in mammals. However, no haploid cell line from an extraembryonic lineage has been achieved yet, which limits the application of ...

Overexpression of Let-7a mitigates diploidization in mouse androgenetic haploid embryonic stem cells
iScienceSummary: Mouse androgenetic haploid embryonic stem cells (mAG-haESCs) can be utilized to uncover gene functions, especially those of genes with recessive effects, and to produce semicloned mice when injected into mature oocytes.
