Experimental details: Figure 8 VEGF expression. Tissue samples were collected, decalcified and processed for immunohistochemistry at day 17 of the study. Staining intensity for VEGF based on the number of pixels associated with the DAB staining. The results are represented as mean +- standard deviation of eleven animals. One-way ANOVA with Tukey's multiple comparison test was used to assess intergroup differences ( ** P < 0.01, *** P < 0.001, **** P < 0.0001).

PCR ( a ) and WB ( b ) analysis of the RNA and protein levels of NOTCH2, VEGF, and bFGF in ECFCs after NC and NOTCH2 inhibitor transfection. c ELISA analysis of VEGF secretion from ECFCs after transfection. Tube formation ( d , e ), Transwell ( f , g ), wound healing ( h , i ), and proliferation ( j ) assays revealed that inhibiting NOTCH2 impairs angiogenesis. k , l CAM angiogenesis assays revealed that when injected with ECFCs in which NOTCH2 was inhibiting, new chick embryo vessel density decreased.

Experimental details: 4 FIGURE Citrulline ameliorates fibrosis and promotes angiogenesis in the placenta. l -Citrulline (2.5 g*L -1 in drinking water) was administered from the day of mating to the end of the experiments. At GD21, the placentas were fixed in formalin and embedded in paraffin. Placenta sections were stained using Masson's trichome staining kit, and the blue colour indicates positive stain for collagen. Magnification: 100x (a). Collagen staining was quantified using ImageJ software (b). n = 6 animals per group. The expression of remodelling genes, for TGF-beta ( Tgfb ) and MMP 2 and 9 ( Mmp2 and Mmp9 ), in the placenta was analysed by quantitative PCR (c). The expression of endothelial cell marker CD31 was examined by immunohistochemistry (IHC) staining using anti-CD31 antibody. Magnification: 100x (d). Black arrows indicate small vessels with positive stain. The expression of angiogenic ( Plgf , placental growth factor; Vegf , vascular endothelial growth factor; Fgf2 , fibroblast growth factor) and anti-angiogenic ( Flt-1 , fms-like tyrosine kinase 1; Thbs , thrombospondin; Angpt2 , angiopoietin 2; Lkb1 , liver kinase b1) genes in the placenta was measured by quantitative PCR (e). The protein expression of CD31 (f), placental growth factor (PlGF), and vascular endothelial growth factor (VEGF) (g) in the placenta was measured by Western blotting. beta-tubulin was used as internal control. Data are presented as means +- SEM, with individual values. * P < 0.05, significantly different
