Figure 5. Ablation of the lateral line does not affect pallial cell proliferation.
On 3 dpf, 30 min exposure to CuSO4 destroyed kinocilia (as visualized by acetylated tubulin) associated with hair cell cupulae (white arrows) along the larval zebrafish lateral line (A). Prior ablation of lateral line hair cells on 3 dpf did not affect the number of PCNA+ cells in the pallium reared in unrestrained conditions (B; n = 7). Scale bar = 40 µm. n.s., not significant. Data are represented as mean ± SEM.
