Cellular complexity of the peripheral nervous system: Insights from single-cell resolution

Area of Science:

• Neuroscience
• Genomics
• Cell Biology

Background:

• Single-cell RNA sequencing (scRNA-seq) provides high-resolution transcriptional profiling of individual cells.
• scRNA-seq application in the peripheral nervous system (PNS) identifies diverse cell populations like neurons, glial cells, immune cells, and vascular cells.
• Understanding cellular heterogeneity is crucial for comprehending tissue function and pathology.

Purpose of the Study:

• To compile and describe the cellular heterogeneities identified in the peripheral nervous system.
