Enhancing Genetic Stability in hPSC Cultures: Introducing eTeSR™ for Single-Cell hPSC Maintenance
In this Innovation Showcase talk from ISSCR 2023, Dr. Adam Hirst, one of STEMCELL’s Senior Scientists, introduces eTeSR™, a novel hPSC maintenance medium developed specifically to maintain cell quality when passaging hPSCs as single cells.
Genetic instability in human pluripotent stem cell (hPSC) cultures remains a substantial concern for research and therapeutic development outcomes, especially when cells are exposed to stressful culture conditions such as long-term single-cell passaging. In this presentation, STEMCELL Technologies’ Senior Scientist Adam Hirst introduces eTeSR™, an hPSC maintenance medium specifically developed to preserve genetic stability and cell quality during routine single-cell passaging. The formulation is optimized to support hPSC expansion while reducing cellular stress and has been tested using large-scale, long-term genetic stability studies across multiple hPSC lines. When compared against other commercially available media, the data demonstrate that hPSCs cultured in eTeSR™ display stable morphology, preserved pluripotency and trilineage differentiation, and higher genetic stability.

Key topics covered in this webinar:
Long-term single-cell passaging places hPSCs under significant selective pressure, increasing the risk of recurrent genetic abnormalities that can affect research outcomes. By using eTeSR™, a medium specifically designed for hPSCs maintained as single-cell cultures, researchers can preserve genetic stability to achieve more reliable, reproducible gene editing, clonal expansion, and downstream differentiation workflows.
