title: Efficient derivation of functional dopaminergic neurons from human embryonic stem cells on a large scale.
abstract: Cell-replacement therapy using human embryonic stem cells (hESCs) holds great promise in treating Parkinson's disease. We have recently reported a highly efficient method to generate functional dopaminergic (DA) neurons from hESCs. Our method includes a unique step, the formation of spherical neural masses (SNMs), and offers the highest yield of DA neurons ever achieved so far. In this report, we describe our method step by step, covering not only how to differentiate hESCs into DA neurons at a high yield, but also how to amplify, freeze and thaw the SNMs, which are the key structures that make our protocol unique and advantageous. Although the whole process of generation of DA neurons from hESCs takes about 2 months, only 14 d are needed to derive DA neurons from the SNMs.
