Induced pluripotent stem cells (iPS-cells) have significantly expanded our experimental possibilities, by creating new strategies for the molecular study of human disease and drug development. Treatment of pain has not seen much improvement over the past decade, likely due to species differences in preclinical models. Thus, iPS-cell derived sensory neurons offer a highly welcome translational approach for research and drug development. Although central neuronal differentiation is relatively straightforward, the successful and reliable generation of peripheral neurons requires more complex measures. Here, we describe a small molecule-based protocol for the differentiation of human sensory neurons from iPS-cells which renders functional nociceptor-like cells within several weeks.
