摘要: Objectives: Nerves and blood vessels form a close association during embryogenesis. Growth guidance factors initially attributed to either nerves or are now known affect both tissues; prominent among these is vascular endothelial growth factor (VEGF). The authors investigated whether axons would associate with in regenerating system questioned VEGF integral neurotization following axotomy.Methods: In hamsters 8–12 weeks of age, the accessory nerve (CN XI) retractor muscle cheek pouch was cut proximal stump reattached ectopically onto muscle. Vascular casting immunolabeling were used quantify extent neurovascular regeneration. A role for using immunolocalization its receptor (sVEGFR2) as well local sequestration soluble (sVEGFR1).Results: Regenerating aligned microvessels vasa nervorum along “chaperone” region o...
