While 87.9% (51/58) of mice transplanted with isogenic HNF1A-MODY iPSC Het (+/R200Q) and R200Q-corrected WT (+/+) lines were teratoma-free, the majority (61.5%, 8/13) of the HNF1A-MODY iPSC Het (+/460ins) and control iPSC WT lines showed teratoma formation (Fig. S11i). This evidence concerns the gene HNF1A and teratoma.
