These results help to guide researchers in the choice of appropriate astrocyte marker and suggest differences in …

Witryna14 maj 2024 · Nevertheless, cells in cluster 6 were also unique likely because of their immature astrocyte phenotype. In addition to cluster 6, cells in cluster 11 expressed some of the astrocytic markers ( Batiuk et al., 2024 ); however, Gfap, Aldh1L1, and many additional astrocyte markers were expressed at very low levels, and thus these cells … Witryna12 maj 2024 · Mature astrocytes partially lose these functions but gain new functions essential for adult CNS homeostasis. In pathological conditions, astrocytes become “reactive”, which disrupts their mature homeostatic functions and reactivates some immature astrocyte-like properties, suggesting a partial reversal of astrocyte …
