Figure Lengend Snippet: Cell viability of HDF cells treated with Ch NPs at concentrations of 2.5–160 µg/mL for 24 h. Viability was determined using the MTT assay and expressed as mean ± SE (n = 3). Different letters indicate statistically significant differences ( p < 0.05).

Article Snippet: The biocompatibility of Ch NPs was evaluated using primary HDF (ATCC ® PCS-201-012TM [ ], American Type Culture Collection, Manassas, VA, USA) and HaCaT cells (Cat. No. T0020001, AddexBio, San Diego, CA, USA).

Figure Lengend Snippet: Immunofluorescence intensity analysis for COL I, III, IV, V, VI, COL I/COL III ratio, TNMD and aSMA in hTCs and hDFs after 4, 7 and 10 days of culture under PLLA, +TGFB2, +MMC and +MMC + TGFB2 conditions. (∗p < 0.05 vs respective PLLA group at the same time point; ‡p < 0.05 vs respective + TGFB2 group at the same time point; #p < 0.05 vs. respective + MMC group at the same time point; §p < 0.05 between cell types at the same time point and condition; &p < 0.05 vs. respective condition at day 4).

Venn diagram representing the top 100 protein hits in TT group vs. hTCs ( B ) and hDFs ( C ) cultured under PS, PLLA, +TGFB2, +MMC and +MMC + TGFB2 conditions. Gene ontology analysis ( D ) of the top 100 protein hits in TT group vs. hTCs and hDFs cultured under PS, PLLA, +TGFB2, +MMC and +MMC + TGFB2 conditions. N = 3.

Figure Lengend Snippet: Gene set enrichment analysis of the quantitative proteomic profile of hDFs cultured for 10 days under PLLA ( A ), +TGFB2 ( B ), +MMC ( C ), and +MMC + TGFB2 ( D ) conditions. All contrasts were performed against hDFs cultured for 10 days under TCP conditions. A gene set containing all protein hits in TT group vs hDFs TCP group (tendon signature) was used for all analyses. Venn diagram summarizing the different core enrichment proteins identified in PLLA, +TGFB2, +MMC and +MMC + TGFB2 groups by means of gene set enrichment analysis ( E ). GO analysis of the core enrichment proteins identified in +MMC + TGFB2 group by means of gene set enrichment analysis ( F ). (NES: normalised enrichment score). N = 3.

Figure Lengend Snippet: Heatmap displaying the quantitative matrisome of hTCs and hDFs cultured under PLLA, +TGFB2, +MMC and +MMC + TGFB2 conditions for 10 days. Hierarchical clustering was applied to all samples. The heatmap displays the z-scores for every matrisome protein identified, being these grouped into the different matrisome categories. Both hTCs and hDFs clustered first in relation to TGFB2 treatment (alone or in combination with MMC), and ultimately in relation with the experimental conditions to which these were subjected. The + MMC + TGFB2 experimental condition exerted the highest changes into the quantitative matrisome of hTCs and hDFs, increasing ECM protein levels throughout all the categories of the matrisome. N = 3.
