Abstract
Current protocols for preparing primary sensory neuron cultures are inadequate when studying individual subpopulations of dorsal root ganglion (DRG) neurons. The DRG is made up of a heterogeneous population of cells, making it difficult to study treatment effects on any given population in mass cultures. Thus, we describe a procedure using magnetic beads from Dynal™ to select and plate viable populations of neurons based on expression of specific cell surface markers. We show that, by the use of the lectin IB4, we can select a highly enriched viable subpopulation of GDNF-responsive DRG neurons, leaving a viable population of non-selected IB4−ve, Trk+ve neurons. Key factors for successful cultures are (i) quick and careful dissection of DRGs from 4- to 5-week-old Sprague–Dawley rats, (ii) adequate removal of debris and non-neuronal contamination and (iii) gentle handling of bead-bound cells during selection.
