A protocol to differentiate nociceptors, mechanoreceptors, and proprioceptors from human pluripotent stem cells

Human pluripotent stem cells (hPSCs) show promise for studying diseases affecting cell populations that are not easily available, including sensory neurons (SNs). Here, we present a differentiation protocol in chemically defined conditions to generate peripheral SNs from hPSCs. We describe four main steps: expansion of hPSCs, neural crest cell (NCC) differentiation, NCC dissociation and replating, and sensory neuron (SN) differentiation. This protocol enables generation of a mechanoreceptor-enriched culture or a population containing all three SN subtypes (nociceptors, mechanoreceptors, and proprioceptors). For complete details on the use and execution of this protocol, please refer to Saito-Diaz et al. (2021).
