Deletion of AmeloD in adult mice inhibits incisor regeneration.
A, photographic analysis of 6-week-old WT and AmeloD-KO mice after clipping the lower left incisor. First column, mice incisors at day 0 after clipping half of the left lower incisor. Second column, mice incisors at day 3 of recovery. Third column, radiographic analysis of clipped incisors after 3 days of recovery. B, quantified data of the recovered incisor length after cutting (n = 6). The mean is shown as lines. Error bars represent S.D. **, p < 0.01 with a two-tailed t test.
