Fig. 5.

Representative forward and backward collected SHG images of the ${\mathrm{Dcn}}^{-/-}$ AP (a) and (b) wt AP. The segmented features in the backward channel arise from destructive interference from shorter coherence length structures, which are more pronounced in the ${\mathrm{Dcn}}^{-/-}$. $\text{Scale bar}=50\mu \mathrm{m}$.
