Splanchnic vascular cast images of PPVL and sham mice after the injection of Batson's solution into the ileocolic vein. Representative stereomicroscopic and scanning electron microscopic photographs of the mesentery showing increased splanchnic neoangiogenesis in PPVL mice (c, d) in comparison with sham mice (a, b), as also confirmed on CD31 immunohistochemistry (e, f, arrows indicate blood vessels). Sprouting angiogenesis (g, arrows) was observed more frequently in PPVL than in sham mice. Illustration of intussusceptive angiogenesis in PPVL mice is additionally shown (h, arrow).
