Using Automation to Assess the Impact of eTeSR™ on Genetic Stability of Human Pluripotent Stem Cells
In this webinar, Kimberly Snyder, a Senior Scientist in Pluripotent Stem Cell Biology at ƽ Technologies, explores the critical relationship between culture methods and the long-term genetic stability of human pluripotent stem cells (hPSCs). Kimberly presents the rationale, design, and outcomes of a large-scale, automated study evaluating the genetic stability of hPSCs under single-cell passaging conditions, highlighting the development of eTeSR™, a culture medium specifically optimized to mitigate the risks associated with single-cell passaging.

In this webinar, Kimberly Snyder, a Senior Scientist in Pluripotent Stem Cell Biology at ƽ Technologies, explores the critical relationship between culture methods and the long-term genetic stability of human pluripotent stem cells (hPSCs). Aggregate-based passaging, when paired with best practices like highly characterized cell banks and standardized protocols, results in remarkably low rates of genetic abnormalities. However, single-cell passaging of hPSCs offers a scalable solution well-suited for integration into automated systems.
Kimberly presents the rationale, design, and outcomes of a large-scale, automated study evaluating the genetic stability of hPSCs under single-cell passaging conditions. Highlighting the development of eTeSR™, a culture medium specifically optimized to mitigate the risks associated with single-cell passaging, she outlines a high-throughput experiment involving 288 samples and 72 clonal lines. eTeSR™ was found to significantly reduce the occurrence of de novo genetic aberrations compared to other commercially available media, with chromosomal stability maintained in over 75% of clones during 20 weeks of single-cell culture.
