An Optimized Protocol for the Generation of Midbrain Dopamine Neurons under Defined Conditions
Carlos W. Gantner, Agustín Cota-Coronado, Lachlan H. Thompson, Clare L. Parish
Abstract
Here, we 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 production of dopamine neurons for the purposes of transplantation, studying development and homeostasis, disease modeling, drug discovery, and drug development. For complete details on the use and execution of this protocol, please refer to Gantner et al. (2020) and Niclis et al. (2017a).
