Figure Lengend Snippet: Establishment of AGA model and treatments. (A) Schematic diagram of the establishment of the AGA model and treatments. (B) Immunofluorescence staining, section scanning, and whole-mount imaging of clarified tissues demonstrating the transdermal efficacy of TQC and tFNAs. Blue: DAPI; Red: Cy5-TQC/Cy5-tFNAs. (C) Time-course observations of hair growth of samples at 1, 4, 7, 10, 14, 15, 18, 21, 24, and 28 days (n = 5). (D) Whole-mount imaging and magnified views of treated samples shot with a Light Microscopy: Control, AGA, Minoxidil, Que, tFNAs, and TQC (n = 5). (D) (E) Longitudinal-sectional and cross-sectional HE staining of treatment groups: Control, AGA, Minoxidil, tFNAs, Que, and TQC. Scale bars: 3 mm (overview), 300 μm/500 μm (magnified regions). Black triangle: Sebaceous gland; black arrowheads: Hair shaft; yellow arrowheads: Hair bulb; green arrowheads: Hair papilla; blue arrowheads: Melanocyte (n = 5). (F) Quantitative image analysis of whole mount hair follicles density (number/view) in figure D. Data are expressed as mean ± SD (n = 5). Statistical significance was determined by one-way ANOVA with Tukey's post hoc test. (G) Quantitative image analysis of hair follicle density (number/mm) in cross-sectional HE staining (figure E). Data are expressed as mean ± SD (n = 5). Statistical significance was determined by one-way ANOVA with Tukey's post hoc test. (H) Ratio of anagen to telogen follicles in longitudinal-sectional HE staining (figure E). Data represent mean ± SD (n = 5) and are analyzed using one-way ANOVA with Tukey's test. The following symbols denote differences compared to each group: (∗) control, (#) AGA, (&) AGA + Minoxidil, (@) AGA + tFNAs, ($) AGA + Que. Significance levels are: ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.

Article Snippet: After 14 days’ model establishment, the mice were assigned to the following groups: AGA model group, Minoxidil ( U10858 , MCE, USA, 5 %)-treated group, Que (20 μM)-treated group, tFNAs (250 nM)-treated group, and TQC (tFNAs/Que: 250 nM/20 μM)-treated group.

Figure Lengend Snippet: The role of TQC in mediating Wnt/β-catenin signaling and hair follicle regeneration in AGA mice. (A) Western blot analysis of β-catenin, GSK3β, CK-1α, and APC protein expression in different treatment groups. GAPDH was used as an internal control (n = 5). (B) Quantitative analysis of protein expression levels relative to the control group. Data are expressed as mean ± SD (n = 5). Statistical significance was determined by one-way ANOVA with Tukey's post hoc test. (C) Immunohistochemical staining of GSK3β, CK-1α, and APC in skin tissue sections. Magnified images show representative areas of staining. Scale bars: 3 mm (original magnification) and 500 μm (magnified), (n = 5). (D) Immunofluorescent staining of Ki67 (green) and KRT14 (red) in skin sections. DAPI (blue) was used for nuclear staining. Merged images show the co-localization of Ki67 and KRT14. Scale bars: 2 mm (original magnification) and 200 μm (magnified). (E) Quantification of β-catenin, GSK3β, and CK-1α protein expression on immunofluorescent staining sections calculated by ImageJ (n = 5). Data are expressed as mean ± SD (n = 5). Statistical significance was determined by one-way ANOVA with Tukey's post hoc test. (F) Quantification of Ki67 and KRT14 positive area. Data are expressed as mean ± SD (n = 5). Statistical significance was determined by one-way ANOVA with Tukey's post hoc test. The following symbols denote significant differences compared to each group: (∗) control, (#) AGA, (&) AGA + Minoxidil, (@) AGA + tFNAs, ($) AGA + Que. Significance levels are: ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
