Protocol to Prepare Single-Cell Suspensions from Mouse Vagal Sensory Ganglia for Transcriptomic Studies

Vagal sensory neurons relay viscero- and somatosensory information from within the body and play a key role in maintaining physiological homeostasis. We recently characterized the diversity of vagal sensory neurons in the mouse using a single-cell transcriptomics approach. Here, we provide an in-depth protocol for the extraction of mouse vagal ganglia and the production of high-quality single-cell suspensions from this tissue. This effective protocol can also be applied for use with other peripheral and central neuron populations with few modifications. For complete details on the use and execution of this protocol, please refer to Kupari et al. (2019).
