( a ) Protein level of pro-collagen type 1 alpha 1 secreted by skin cells (Hs68) was enhanced by combined treatment of andrographolide and BPE ( n = 6 per group). ( b ) Protein level of MMP-1 secreted by skin cells (Hs68) was reduced by combined treatment of andrographolide and BPE ( n = 4–5). ( c ) Gene expressions of different types of collagens were enhanced by co-treatment of andrographolide and BPE ( n = 6 per group). ( d ) Representative images of artificial 3D skin. Scale bar = 275 μm. The blue color represents collagen. ( e ) Relative collagen content in dermal area of artificial 3D skin.

Article Title: Compatibilizing of cotton fabric with hydrophobic drug cover layer for anti-inflammatory performance with the implementation of ibuprofen

doi: 10.1038/s41598-024-57883-5

Figure Lengend Snippet: The influence of all tested materials on cell viability in MTT reduction assay. The tested materials: raw cotton, A, B, C, D, E, F, G, H, I, J, K and L were added to L929 fibroblasts or human Hs68 fibroblasts cell cultures. The cell viability was estimated as a percentage of cells, which were able to reduce tetrazolium salt (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) (MTT). NC negative control (cells treated with 0.03% H 2 O 2 ), PC positive control (cells in medium alone), raw cotton—tested materials before IBU application. Results are showed as mean ± SD. The black line indicates the minimal percentage of viable cells (70%) required to confirm the biomaterial as non-cytotoxic at the in vitro level. Three experiments were performed in triplicates for each experimental variant. Statistical analysis was performed using the nonparametric U Mann–Whitney test with significance, p < 0.05 (asterisk: unstimulated cells vs. stimulated cells).

Figure Lengend Snippet: Production of pro-inflammatory TNF-a ( A ) and IL-B ( B ) by human Hs68 fibroblasts. The human Hs68 fibroblasts were stimulated with LPS from E. coli alone, as well as with samples B, C, E, F, G and L alone or samples in combination with LPS from E. coli (1 µg/mL) or with IBU alone and with LPS from E. coli in combination with ibuprofen (IBU. 50 µg/mL). Control cells were subcultured in the medium alone. The supernatants were collected for the assessment of interleukin (IL)-1β or IL-TNF-a by the enzyme-linked immunosorbent assay (ELISA). The results are presented as mean values ± SD. Three experiments were conducted in triplicates for each experimental variant. Statistical analysis was performed using the nonparametric U Mann–Whitney test with significance, p < 0.05 (asterisk: unstimulated cells vs. stimulated cells); or Kruskal–Wallis test (filled circle: LPS vs LPS + dressings).
