Gene expression analysis from bulk RNA seq data of the differentiated mDA cells at day 35 confirmed the expression of key neuronal markers (e.g. FOXA2 and MAP2) compared to undifferentiated WIBR3 hPSC cells, indicating robust differentiation within these hPSC-derived cell lines expressing familial PD mutations (Figure 1B). This evidence concerns the gene FOXA2 and Parkinson disease.
