Figure Lengend Snippet: a Distribution of fibroblast subtypes expressed as a difference between FD-treated and FD-fellow sclera (two-sided chi-square test with Bonferroni correction for multiple testing). The X-axis indicates the subtypes corresponding to the uniform manifold approximation and projection plot. The Y-axis shows the log-transformed P -value obtained by the chi-square test between FD-treated and FD-fellow eyes’ scleral fibroblast subtypes.

In the FDM mouse model, OE Wnt5a -AAV injected + FDM mice developed less myopic shift than did the vector-AAV injected mice ( e ). In comparison with the vector-AAV injected eyes, OE Wnt5a -AAV injected + FD eyes exhibited a significant difference for axial length ( f, n = 13 for vector-AAV injected group and n = 16 for OE Wnt5a -AAV injected group, two-way repeated measures ANOVA with Bonferroni’s post hoc tests, two-sided, for refraction and for axial length). g , h Wnt5a overexpression can partially rescue the COL1A1 protein level, which is downregulated by FD. n = 7, ordinary two-way ANOVA with Bonferroni’s post hoc test (two-sided).

Figure Lengend Snippet: Abnormal visual stimulation propagating via the retina-choroid-sclera signalling cascade reduces Wnt5a hi fibroblast numbers and/or activity, and thus Wnt5a secretion. Subsequently, the expression of genes for ECM molecules such as Col1a1 , Sparc , Pcolce , Pcelce2 , Adamts2 , Bmp1 , and Igta2 is downregulated via the noncanonical Wnt signalling pathway (Wnt5a-Ca 2+ -CaMKII). This response may disrupt ECM structural organisation, decrease collagen I level, and reduce the collagen fibril diameter, finally resulting in myopia progression due to increased distension of the posterior sclera under constant intraocular pressure.
