Abstract:
The transient receptor potential vanilloid subfamily 1 (TRPV1) is a polymodal nociceptor that is highly expressed in sensory nerves. Activation of TRPV1 receptors excites primary afferent nociceptors by opening cation channels, allowing the influx of Na+ and Ca2+ ions into the cytoplasm. Here, a TRPV1 knockout human embryonic stem cell line was generated using the CRISPR/Cas9 genome-editing technology to further study the function of TRPV1. The cell line confirmed with normal pluripotency and karyotype.
