Figure Lengend Snippet: ( A – C ”) Representative images of fluorescent isolectin B4-stained retinas either from P6 neonates fed for 3 days by dams injected on P3 with PBS ( A ), control IgG2a/b Abs ( B ), or BMP9/10 blocking Abs ( C – C ”). ( C’ , C” ) are higher magnification images of the relevant boxed areas in C. a, artery; v, vein; scale bars, 500 μm. ( D–L ) Higher magnification showing retinal vasculature fields between an artery and a vein (Plexus, D–F ), or at the front of an artery ( G–I ) or a vein ( J–L ) from neonates treated as in ( A–C ). Scale bars, 100 μm. ( M–O ) Scatter plots showing the vascular density on retinal ‘petals’ at the plexus ( M ), artery front ( N ), or vein front ( O ). Data represent mean ± s.e.m. (n = 6 pups per group from 2 dams); **** P < 0.0001, ANOVA and Kruskal-Wallis test. Arrows indicate AVMs, defined as direct shunts between an artery and a vein.
Article Snippet: After washing 3 times with PBST, serial dilutions of individual mouse serum samples and reference mouse anti-BMP9 Ab (MAB3209, R&D Systems) (diluted in 1% BSA PBS) were prepared and 100 μL/well were incubated for 2 h at RT.
Techniques: Staining, Injection, Control, Blocking Assay
