Figure Lengend Snippet: Histological analysis of the fibrosis in response to an elevated PA gradient. A, Picrosirius red stain demonstrating dense fibrosis in the RV of a rabbit that underwent PAB. B, Picrosirius red stain demonstrating lack of fibrosis in the RV of the control rabbit. C, Masson's trichrome stain demonstrating dense fibrosis in the RV of a rabbit that underwent PAB. D, Masson's trichrome stain demonstrating relatively little fibrosis in the RV of the control rabbit. E, Masson's trichrome stain of the RV of a 2-month-old that had undergone bilateral banding of the branches of the PA, demonstrating prevalent fibrosis. F, Masson's trichrome stain of the RV from a 20-year-old with severe PAH, demonstrating prevalent fibrosis. G, Masson's trichrome stain of the RV from a 38-year-old with severe PAH, demonstrating prevalent fibrosis. H, Masson's trichrome stain of the RV from a 20-year-old otherwise healthy female brain-dead donor. Scales are 200 μm.

Article Snippet: Samples were stained using StatLab's Masson's Trichrome Stain Kit (StatLab, Cat: KTMTR EA).

Article Title: The Vasopressin Receptor Antagonist Tolvaptan Counteracts Tumor Growth in a Murine Xenograft Model of Small Cell Lung Cancer

Figure Lengend Snippet: Masson’s trichrome staining and angiogenesis evaluation. ( a ) Masson’s trichrome staining labels collagen in blue, nuclei in dark brown, muscle tissue in red, and cytoplasm in pink. Images are representative of tumor masses of control and tolvaptan groups, whereas dot blots represent mean of tumoral fibrotic area (number of blue pixels) from each group (magnification 100× and 400×) (n = 5). ( b ) IHC analysis of CD34: images are representative of positive stain and the graph shows relative quantification (magnification 100× and 400×) (n = 5). ( c ) Western blot analysis of VEGF and CD34 and their normalized quantification vs. stain-free (n = 5). (* = p ≤ 0.05 vs. control group).

Article Snippet: Tumor mass sections (5 μm thick) were stained with Masson’s trichrome (MT) staining procedure (14-118 DDK Italia S.r.l., Milan, Italy) according to the manufacturer’s instructions.

Techniques: Staining, Control, Quantitative Proteomics, Western Blot
