RNA sequencing of winner and loser hPSCs grown in either separate culture or upon co-culture.
The observation that human Pluripotent Stem Cells (hPSCs) may acquire non-random genetic changes during prolonged culture is a major concern for their use in regenerative medicine and disease modelling. The mechanisms through which genetically variant cells are selected for in culture remain poorly characterized. We have shown that the dominance of variant hPSCs with enhanced growth rates is enhanced through competitive interactions resulting in the elimination of the slower growing loser population. This experiment compares the gene expression of winner (H7v1,12,17q,20q-GFP) and loser (H7v1q) grown either in separate culture or competitively in co-culture together.
