ABSTRACT
Haploid trophoblast stem cells (TSCs) are advanced in studying placental development for their placental precursor and homozygous features. Here, we describe how to generate haploid-induced TSCs (haiTSCs) from haploid embryonic stem cells with a Tet-on system. Our haiTSCs can maintain haploidy long-term and can produce genome-wide mutants combined with transposons. It is promising in high-throughput genetic screening of trophoblast-specific modulators. For complete details on the use and execution of this protocol, please refer to Peng et al. (2019).
