Fig. 4

Dynamics of actinotrichia regeneration correlate with lepidotrichia regrowth. (A-P) Immunofluorescence staining for And1 (green) in osterix:nlsGFP fish (osteoblasts; red) at different time points after amputation (dpa). Bone matrix/tissue autofluorescence shown in blue. (Q) Quantification of the length of And1-positive regions at different time points during regeneration. Each fin was represented by the measurements of the second, third, and fourth ray relative to the edge of both lobes. N ≥ 4 fins for each time point. 6 rays per fin. Error bars represent SEM. (J′) Magnification of a single ray at 5 dpa, showing inverse correlation between And1 deposition and osterix:nlsGFP. The V-shaped tip of the regenerating lepidotrichium indicates an initiated ray bifurcation.
