New vessel formation after surgical brain injury in the rat?s cerebral cortex. II. Formation of the blood vessels distal to the surgical injury
Languages of publication
We investigated the features of newly formed blood vessels after surgical brain injury of the rat?s cerebral cortex distal to the operated region. We document the process of split mature blood vessels by an endothelial bridge and morphological features of newly formed vessels. We did not observe a disruption of brain parenchyma. The endothelial lining in vessels was complete. The morphological features of the endothelial cells and basement membrane show that non-sprouting angiogenesis takes place distally to the surgical injury.
