doi: 10.1038/s41598-019-41355-2

Figure Lengend Snippet: Influence of CS, HA, SH, and HE on MMP2 and TIMP3 formation and MMP2 activity in hBMSC. 7,000 hBMSC/cm 2 were plated in basic medium and treated with CS, HA, SH, and HE (200 µg/mL each). At day 22 after plating cells and conditioned medium were analyzed. ( A ) mmp2 expression was assessed by qPCR, normalized to the expression of the house-keeping genes (hkg) gapdh , β-actin , and rps26 , and related to untreated control (Ctrl, set to 1) using the comparative quantitation method. Conditioned medium of hBMSC was analyzed for MMP2 protein content using commercially MMP2 ELISA Kit ( B ) and for MMP2 enzyme activity with fluorogenic peptide (MCA-Pro-Leu-Ala-Nva-Dpa-Ala-Arg-NH 2 ) as a substrate ( C ). ( D ) The relative MMP2 activity per MMP2 protein amount was calculated from fluorescence signals (MMP2 activity) and ELISA data (MMP2 protein). ( E ) timp3 expression was assessed by qPCR as described. ( F ) TIMP3 protein amount released into the conditioned medium was determined by ELISA. TIMP3 protein in the pericellular environment of hBMSC was analyzed by Western blotting with chemiluminescence detection. ( G ) shows a representative Western blot (cropped), according full-length blots presented in Supplemental Fig. . The chemiluminescence signals of four independent Western blots were quantified densitometrically and normalized to GAPDH and β-tubulin (Tub) as internal loading controls ( H ). ( I ) shows the total TIMP3 content related to Ctrl and the distribution of TIMP3 calculated from Western blot data (pericellular, ECM-associated TIMP3) and ELISA data (released TIMP3). The ratio of released MMP2 protein to released TIMP3 is shown in ( J ). The results are presented as mean ± SEM. Significant differences of treatment vs. Ctrl were analyzed by one-way ANOVA/Bonferroni’s post-test ( A – F , H ,J), and of SH vs. HE two-way ANOVA/Bonferroni’s post-test ( I ) and are indicated with *(p < 0.05), **(p < 0.01) and ***(p < 0.001), n = 4.
