Fig 3. TGF-β neutralization (5 mg/kg, 3/week) had no effect on early ascending and suprarenal aortic dilation confirmed by in vivo ultrasonography.

Aortas of infused mice were ultrasonically scanned at day 4 of infusion. (A) Aortas were imaged in the parasternal long axis view to obtain the measurements of ascending aortas. (B) Two-dimensional images (B mode) of short-axis scans were acquired to determine the maximal diameters of suprarenal aortas. Histobars represent mean ± SEM.
