Additionally, we co-cultured pairs of control clonal populations and single-cell isolated spontaneously arising fusion events to generate clonal fusion populations with matched parental controls, referred to as matched fusion-parent trios. All fusion clonal populations from matched trios were also profiled using WGS to analyze CNV versus matched parents, and all surviving fusion and control clonal populations from the matched trios were profiled in biological triplicate by TagSeq (3' tag-based RNA-seq) for transcriptomic analysis.2026/09/08GSE346002GSM10021240GSM10021237GSM10021236GSM10021258GSM10021257GSM10021235GSM10021234GSM10021256GSM10021233GSM10021255GSM10021254GSM10021232GSM10021231GSM10021253GSM10021230GSM10021252GSM10021219GSM10021218GSM10021239GSM10021217GSM10021238GSM10021251GSM10021250GSM10021248GSM10021226GSM10021225GSM10021247GSM10021224GSM10021246GSM10021245GSM10021223GSM10021222GSM10021244GSM10021221GSM10021243GSM10021242GSM10021220GSM10021241GSM10021229GSM10021228GSM10021227GSM1002124930173346002Homo sapiens
