Figure Lengend Snippet: NM-LP TK /RSV-MnCDs suppresses vascular ingrowth and matrix degradation in AFP-induced disc degeneration through Hippo pathway inactivation. (A–D) Representative IF images and quantitative analyses of CD31 and Tuj1 in IVDs from AFP-induced IVDD mice treated with MCB, TRULI, or their combinations with NM-LP TK /RSV-MnCDs (n = 5). Scale bar, 100 μm. (E–H) IF staining and quantification of COL2A1 and MMP13 expression in NP regions (n = 5). Scale bar, 100 μm. Data are presented as mean ± SD. The comparisons among groups were performed using one-way ANOVA. ∗, P < 0.05; ∗∗, P < 0.01; ∗∗∗, P < 0.001; ∗∗∗∗, P < 0.0001; ns = not significant.

Article Snippet: For immunofluorescence (IF) staining, antigen retrieval was conducted using citrate buffer (0.1 M, pH 6.0), followed by blocking in 10 % normal goat serum (Solarbio, Cat. No. SL038) at room temperature for 1 h. Sections were incubated overnight at 4 °C with primary antibodies targeting ACAN (Cat. No. DF7561, Affinity), COL2A1 (Cat. No. AF0135, Affinity), MMP3 (Cat. No. AF0217, Affinity), MMP13 (Cat. No. 18165-1-AP, Proteintech), CD31 (Cat. No. AF0077, Affinity), p-LATS1 (Cat. No. AF7170, Affinity), p-YAP (Cat. No. AF3328, Affinity), Tuj1 (Cat. No. 66375, Proteintech), CGRP (Cat. No. DF7386, Affinity), SP (Cat. No. DF7522, Affinity), and PGP9.5 (Cat. No. AF5490, Affinity) followed by incubation with appropriate fluorescent secondary antibodies for 2 h at room temperature and counterstaining with DAPI (Beyotime, Cat. No. C1006).
