Transcriptomic profile of human induced pluripotent stem cells at single cell resolution.. Transcriptomic profile of human induced pluripotent stem cells at single cell resolution.

We assessed the pluripotency of human induced pluripotent stem cells (iPSCs) maintained on an automated platform using StemFlexTM and TeSRTM-E8TM media. Single-cell transcriptome sequencing was performed for 20,962 cells from two cell lines grown in the two media. Analysis of transcriptomic profile revealed similar expression of core pluripotency genes, as well as genes associated with naive and primed states of pluripotency. Single cell analysis of the four samples revealed a shared subpopulation structure with three main subpopulations different in pluripotency states. By implementing a machine learning approach, we estimated that 60-96% of the cells in the ground/naive subpopulations and 98-99% of the cells in the primed subpopulations are similar between all four samples. The single cell RNA sequencing analysis of iPSC lines grown in both media is the first report of the molecular pathways modulated in StemFlex medium and how they compare to those modulated in TeSR-E8 medium.
