Generation and characterization of two human induced pluripotent stem cell lines from young and older male donors

Area of Science:

• Stem cell biology
• Gerontology
• Cardiovascular disease research

Background:

• Advanced age is a major risk factor for cardiovascular diseases.
• Human induced pluripotent stem cells (hiPSC) offer a powerful tool for disease modeling and regenerative medicine.
• Previous work established female hiPSC lines; male lines are needed for comprehensive research.

Purpose of the Study:

• To generate and characterize novel male hiPSC lines from donors of different ages.
• To provide a resource for studying age-related cardiovascular diseases.
• To investigate epigenetic mechanisms in aging.

Main Methods:

• Generation of hiPSC lines from peripheral blood mononuclear cells (PBMCs) of young (18-year-old) and old (80-year-old) male donors.
• Characterization of hiPSC lines for pluripotency markers, karyotype (46, XY), and trilineage differentiation potential.
• Genetic matching of hiPSC lines to their parental PBMCs.

Main Results:

• Two male hiPSC lines were successfully generated and characterized.
• Both lines express key pluripotency markers.
• Both lines demonstrated normal karyotypes and trilineage differentiation capacity, genetically matching their source PBMCs.

Conclusions:

• The generated male hiPSC lines are a valuable resource for regenerative medicine.
• These cell lines will aid in developing human-specific models for aging-associated diseases.
• Further research can utilize these lines to explore epigenetic mechanisms in aging and disease.
