Between-group comparison on SGN density.

group	control	1 dpi	3 dpi	7 dpi	14 dpi
location
apical	41.39 ± 1.00	27.40 ± 0.87	23.08 ± 1.65	18.54 ± 2.38	21.24 ± 1.79
middle	40.93 ± 1.57	35.69 ± 0.56	29.35 ± 1.09	20.76 ± 1.53	19.35 ± 0.70
basal	40.93 ± 1.47	28.54 ± 2.17	22.84 ± 1.07	20.51 ± 1.87	17.92 ± 1.02

N > 5 for each group. The SGN density is measured as the SGN#/10000 nm³. The density measured in Cre⁺ group at every time point after DT injection was significantly lower than the control value at each location (p < 0.001).
