Planarian brain regeneration. Planarian brain regeneration. The CNS of the planarian D. japonica, visualized by whole-mount in situ hybridization against a pan-neural marker (a receptor protein tyrosine phosphatase) (Cebrià et al., 2002c) in intact (A) and regenerating (B) animals. Planarians were decapitated (dashed line in A) and allowed to regenerate for the indicated time points (as indicated in B). Note that de novo brain regeneration is complete after less than 7 days. Dashed line in B corresponds to the original amputation site marked in A. Scale bar: 0.5 mm. Panel A is adapted from Mineta et al. (Mineta et al., 2003), ©2003 National Academy of Sciences, USA; and panels B (1–3 days) are adapted from Cebrià et al. (Cebrià et al., 2002c). Luca Gentile et al. Dis. Model.
