hapln1a expression pattern at different time points in regenerating fin.
Whole mount in situ hybridization for hapln1a on regenerating fins at different time points. The hapln1a gene is not expressed during normal fin growth (uncut). Expression of hapln1a initiates around 2 dpa and is maximally expressed at 3 dpa, followed by gradual reduction at 5 dpa and 8 dpa. Arrow identifies the distal end of the fin; the arrowhead identifies region of staining (or where staining would be observed in uncut fins). The amputation plane is indicated for 2 dpa, 3 dpa, and 5 dpa, and is out of the field of view for the 8 dpa image. Scale bar is 50 μm.
