Identifying differences in differentiation between adherent and suspension culture for iPSC derived beta cells

Stage 3 cells from a suspension environment and adherent culture were compared and evaluated through RNA sequencing. RNA sequencing data in heatmap and volcano plot evaluation of core endocrine genes showed that expression levels in adherent cells were lower than those expressed in 3D environment. Several genes that are essential for insulin transcription such as NEUROD1, MAFA, PPARGC1A and NKX2.2 along with INS were expressed with higher transcript levels in bioreactor samples. It was observed that genes usually expressed in earlier stages such as FOXA2 and HNF1b had higher expression levels in adherent culture indicating that 2D environment differentiation might be lagging. Overall design: To investigate the impact of cell culture platform on iPSC differentiation into pancreatic beta cells.
