Executive Industry Relevance

Single-nucleus RNA sequencing of low-input mouse sympathetic ganglia enables high-resolution molecular profiling of neuronal and non-neuronal cell types relevant to cardiac innervation. This protocol supports multiplexed sample analysis and long-term preservation, addressing key bottlenecks in nervous system target validation and mechanistic de-risking for cardiovascular disease models. The approach enhances predictive confidence at the discovery and preclinical interface for neuro-cardiac research portfolios.
