    Particle Hydrogels Decrease Cerebral Atrophy and Attenuate Astrocyte and Microglia/Macrophage Reactivity after Stroke

    The authors showed that the direct injection of a hyaluronic acid-based microporous annealed particle hydrogel into the stroke core in mice reduced the percent of highly reactive astrocytes, increased the percent of alternatively activated microglia, decreased cerebral atrophy, and preserves NF200 axonal bundles.
