In a retrospective analysis of more than 30 batches of human ESC-derived FP-mDA neurons transplanted in PD mice, they revealed that the expression of mDA progenitor markers Foxa2, Lmx1a, and Corin and the maturation markers TH, Nurr1, and AADC were not correlated with mDA neuron yield in vivo [194]. Here, FOXA2 is linked to Parkinson disease.
