Heatmap displays cells along the horizontal axis with cell types grouped by color and SSNHL-investigated genes along the vertical axis. The darker the bar the more highly expressed the gene is in a given cell. Cell types include SV cell types (marginal cells in pink, intermediate cells in green, basal cells in light blue), cells at the boundary of the SV (spindle-root cells in gold, fibrocytes in light green), as well as immune cells (macrophages in purple, B cells in blue, and neutrophils in magenta). Spindle and root cell profiles were not distinguishable from each other in this dataset.
