Smooth muscle regeneration in the ureter. Electron microscopic and autoradiographic observations.

摘要: The cellular events taking place during reconstitution of the rabbit ureteral wall following resection a portion its circumference were studied utilizing electron microscopy and autoradiography. It was shown that hyperplasia takes in smooth muscle remnant first 2 postoperative weeks spindle-shaped cells possessing ultrastructural characteristics myoblasts migrate from edges into defect, resulting regeneration muscularis within 5 to 6 time injury.
