Key result
Homozygous TET2 knock-out hiPSC line models loss-of-function mutations to study CHIP-associated cardiovascular disease mechanisms.
Why the study?
Atherosclerotic cardiovascular diseases have been linked to clonal hematopoiesis of indeterminate potential mutations, with TET2 being the second most frequently altered gene.
Population
Genome-edited hiPSC line with homozygous TET2 knock-out and a control line
Comparison
Homozygous TET2 knock-out vs control
Design
In vitro stem cell model development study

Should not change clinical practice in CHIP; leaves open TET2 mechanisms in associated cardiovascular disease.
The generation of a TET2 knock-out hiPSC line provides a novel in vitro model for studying the cellular mechanisms of CHIP-associated atherosclerotic cardiovascular diseases.
Triantafyllou et al. (2026) studied this question. A homozygous TET2 knock-out hiPSC line was generated, modeling loss-of-function mutations for studying CHIP-associated cardiovascular disease mechanisms.
