  • Title: Smooth muscle regeneration in the ureter. Electron microscopic and autoradiographic observations.
    Author: Kiviat MD, Ross R, Ansell JS.
    Journal: Am J Pathol; 1973 Sep; 72(3):403-16. PubMed ID: 4728891.
    Abstract:
    The cellular events taking place during reconstitution of the rabbit ureteral wall following resection of a portion of its circumference were studied utilizing electron microscopy and autoradiography. It was shown that hyperplasia takes place in the smooth muscle of the ureteral remnant during the first 2 postoperative weeks and that spindle-shaped cells possessing the ultrastructural characteristics of myoblasts migrate from the edges of the remnant into the defect, resulting in regeneration of the muscularis within 5 to 6 weeks of the time of injury.
