Astrocyte Blossom
This fluorescence microscopy image showcases astrocytes in culture, with GFAP proteins labeled in yellow and nuclei stained blue. A notable characteristic of astrocytes is their response to injury, where they cluster together and form a reactive aura that appears as an "astrocyte blossom." This phenomenon highlights the astrocytes' role in neuroinflammation and tissue repair, emphasizing their significance in both protective and pathological processes within the brain.
