Abstract
<p>A. Hyaluronan digestion by hyaluronidase was evaluated by staining with hyaluronan binding protein (HABP) (red). Scale: 30 μm. B. Measurement of fluorescence intensity. One way ANOVA test was performed, F(2.57) = 53.169; p<0.001, Dunnett’s C post hoc. C. Representative images of astrocytes transfected with β-actin GFP and either untreated (control) or treated with hyaluronidase or heat inactivated hyaluronidase for 48h. Cell nuclei were visualized with DAPI staining. Scale: 30 μm.D. Morphometric analysis of shape-describing parameters of cells treated as described in C. One way ANOVA test was performed, area: F(2.57) = 2.658; p>0.05, solidity: F(2.57) = 16.814; p<0.001, circularity: F(2.57) = 13.799; p<0.001, branching: F(2.57) = 16.774; p<0,001 Dunnett’s C post hoc test.</p
