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.

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.

Article Title: Evaluation of liposome - encapsulated Centella asiatica ethanolic extract for enhanced in vitro and in vivo wound healing

doi: 10.3389/fmedt.2026.1740835

Figure Lengend Snippet: Effects of liposome-encapsulated C.asiatica extract on fibroblast viability and migration. (A) Cell viability of normal human dermal fibroblasts (NHDFs) treated with EE, blank liposome, LEC, or vitamin E at concentrations of 6.5–100 µg/mL, as determined by the MTT assay. (B) Fibroblast migration assessed by scratch-wound assay following treatment with the same formulations and concentrations. Results are expressed as relative values normalized to the untreated control (set to 100%) and presented as mean ± SD ( n = 3). Statistical analysis was performed using two-way ANOVA followed by Tukey's multiple-comparison test. Different letters above bars indicate statistically significant differences between treatment groups at the same concentration ( p < 0.05 ).

( A ) Liposome-encapsulated C.asiatica extract (LEC)–treated wounds, ( B ) vitamin E–treated wounds, ( C ) blank liposome control group, and ( D ) normal saline group. Black arrows indicate re-epithelialization and restoration of epidermal continuity, yellow arrows indicate fibroblast proliferation and granulation tissue formation, and red arrows indicate neovascularization. The LEC-treated group demonstrates complete re-epithelialization, dense fibroblast proliferation, and enhanced neovascularization compared with control groups. Scale bar = 400 µM.
