An Optimized Protocol for the Generation of Midbrain Dopamine Neurons under Defined Conditions

Gantner C.W., Cota-Coronado A., Thomp L.H.STAR Protocols, 2020

Here, the authors describe a xeno-free, feeder-free, and chemically defined protocol for the generation of ventral midbrain dopaminergic (vmDA) progenitors from human pluripotent stem cells (hPSCs). This simple-to-follow protocol results in high yields of cryopreservable dopamine neurons across multiple hPSC lines. Wnt signaling is the critical component of the differentiation and can be finely adjusted in a line-dependent manner to enhance the production of dopamine neurons for the purposes of transplantation, studying development and homeostasis, disease modeling, drug discovery, and drug development.
