Abstract

Abstract Recently, haploid embryonic stem cells (haESCs) have been established in many species and widely used in forward and reverse genetic screening. Differentiated haploid cell line types in mammals are lacking due to spontaneous diploidization during differentiation that compromises lineage-specific screens. Human embryonic stem cells are widely used in basic and preclinical research. In this work, we report that human haESCs in extended pluripotent culture medium showed more compact colonies, higher efficiency in neural differentiation, and higher stability in haploidy maintenance, which effectively facilitated the derivation of haNSCs. Human haploid neural stem cells (haNSCs) can be generated by differentiation and maintain haploidy and multipotency to neurons and glia in the long term in vitro. After PiggyBac transfection, there were multiple insertion sites in the haNSC genome and the insertion sites evenly spread across all chromosomes. This is the first human haploid somatic cell line with a complete genome, proliferative ability and neural differentiation potential, which provides cell resources for recessive inheritance and drug targeted screening.
