Profiling Specific Inner Ear Cell Types Using Cell Sorting Techniques

Studies of specific tissue cell types are becoming increasingly important in advancing our understanding of cell biology and gene and protein expression. Prospective isolation of specific cell types is a powerful technique as it facilitates such investigations, allowing for analysis and characterization of individual cell populations. Such an approach to studying inner ear tissues presents a unique challenge because of the paucity of cells of interest and limited cell markers. In this chapter, we describe methods for selectively labeling and isolating different inner ear cell types from the neonatal mouse cochlea using fluorescence-activated cell sorting.
