Proteoglycan content determined for PDGF‐BB release from full‐transection Achilles tendons: definition of scores by typical fields of view in Alcian blue‐stained paraffin sections (scores 1–5 above, scale bar = 100 µm) and semiquantitative determination (below). One‐way ANOVA was performed. P values < 0.05 were considered significant (*). If P < 0.01, this was marked by **, and if P < 0.001 by ***. Error bars indicate standard deviations. Biological independent replicates n = 6. Additional images for scores 1–5 can be found in Fig. S4.
