Figure 2.

Lateral line hair cell regeneration of senescent adult zebrafish following hair cell death. 1 year and 3 year old zebrafish were treated with 400 μM neomycin for 1 hour and then allowed to recover for 72 hours. The results are graphed as average number of hair cells per neuromast (± s.d.) for each treatment group. N= 3 adult zebrafish per group, 20+ neuromasts per group; p < 0.001(ANOVA)
