doi: 10.1016/j.jare.2024.07.004
Figure Lengend Snippet: Gas plasma-treated wounds showed a modulated gene expression and connective tissue stain dependent on wound healing stage. Ear wounds of mice were treated with gas plasma as described. ( a ) Gene expression levels of transforming growth factor ( TGFβ ) signaling including SMAD2, CDKN1A, and interleukin 1 ( IL1β ) on both endpoints. ( b ) Immunofluorescence analysis of TGFβ1 and staining quantification on d9 and d20. ( c ) Quantification of TGFβ1 staining on both time points. ( d ) Representative picrosirius red (PSR)-stained connective ear tissue on days 9 (left) or 20 (right) in gas plasma-treated (lower panel) compared to untreated ear wounds of mice (upper panel) showing granulation tissue with collagen fibers (red) in brightfield (left images) and fluorescence microscopy (right images). Enlarged graphs display higher magnification. ( e-f ) Quantification of PSR using ImageJ software compared to untreated ( e ) and healthy ( f ) ear tissue showing fiber intensity on d9 and d20. Data are presented as mean ± S.D. *p < 0.05, **p < 0.01, ***p < 0.001 when compared to control groups (ctrl) with Students t -test (a, c) or ANOVA (e-f). Scale bars are 200 µm (d), 100 µm (d, higher magnifications), and 50 µm (b).

Article Snippet: After incubation with primary antibodies targeting β-catenin, E-cadherin, collagen I, Nrf2, iNOS, and TGFβ1 (all Cell Signaling Technology, Germany), cells or wound tissues were incubated with Alexa Fluor 488 or 594 conjugated secondary antibodies (Life Technologies, Germany) and DAPI to visualize nuclei.
