Brain lesion with regenerative astrocytes

Caption

The image on the left shows a brain lesion (diameter: just under 0.5 mm). Around the perimeter of the lesion, the newly discovered “regenerative” astrocytes begin to seal the defect by forming long cellular extensions (shown in red). Newly formed cell nuclei (shown in blue) migrate along the cellular extensions toward the damaged area. Unaltered astrocytes (shown in green) surround the lesion area. The image on the right shows an enlargement of the marked area in the left image.
