Web12 nov. 2024 · HAP1 is a near-haploid adherent fibroblast-like cell line of human leukemia origin. Such haploid cells are powerful tools for studying gene function as they contain a single copy of the genome and are thus unable to mask the effect of any mutations, which could possibly occur in +/− heterozygotes (Li and Shuai, 2024). Web16 jul. 2024 · The recent availability of somatic haploid cell lines has provided a unique tool for genetic studies in mammals. However, the percentage of haploid cells rapidly decreases in these cell lines, which we recently showed is due to their overgrowth by diploid cells present in the cultures.
