Abstract
High-throughput next generation sequencing technologies are an invaluable tool to gain insight into the transcriptional states of large cohorts of cells. Such data can help to shed light on the organization of tissues and pathways under normal and pathological conditions. In our case, we are using the above technology to decipher how the enkephalinergic medium spiny neurons (MSNs) of the striatum adapt to aging in the presence or absence of BDNF/TrkB signaling. However, sequencing data must be validated, ideally with an alternative method that interrogates the transcriptional state of cells, and is able to detect gene expression in rare single cells or bulk cells with high sensitivity. Thus, we have optimized a protocol for high-throughput microfluidic analysis [Fluidigm Dynamic Array Integrated Microfluidic Circuit (IFC)] to validate RNA sequencing data from a limited number of adult and aged sorted neurons. Here is a detailed description of this protocol.
