Abstract

Aging is a leading risk factor for the development of age-related diseases. However, how aging impacts human induced pluripotent stem cell (hiPSC) reprogramming, age-related epigenetic memory post-reprogramming, differentiation, and its potential applicability to cardiovascular regenerative medicine remains underexplored. We generated, characterized, and validated two hiPSC lines from human peripheral blood mononuclear cells (PBMCs) obtained from whole blood of young and older human donors. The two hiPSC lines expressed four pluripotency markers, have normal karyotypes and trilineage differentiation potential, and genetically match parental PBMCs. These lines are invaluable for regenerative medicine and exploring epigenetic-related molecular mechanisms that underlie aging and aging-related diseases.

Research summary

The paper claims to generate and validate two human induced pluripotent stem cell lines from young and older adults to explore aging-related epigenetic mechanisms. This research is relevant as it addresses the impact of aging on stem cell reprogramming and differentiation, which could contribute to understanding and potentially mitigating age-related diseases.
