Human astrocytes are specialized glial cells of the central nervous system (CNS) that contribute to neuronal support, synaptic regulation, metabolic homeostasis, ion and neurotransmitter balance, and regulation of the blood–brain barrier (BBB). Human astrocytes exhibit substantial regional and functional heterogeneity, with properties that can differ from those of rodent astrocytes, supporting their use in human-focused neuroscience research.
Key Features
-
Primary Human Astrocytes : Isolated from human CNS tissue, retaining characteristics associated with their cellular origin, although culture conditions can influence their phenotype.
-
Astrocytic Markers : Expression of commonly used astrocytic markers, including GFAP, S100B, and AQP4, with marker profiles varying according to phenotype, maturation state, and regional origin.
-
Functional Roles : Involved in glutamate uptake, ion and water homeostasis, metabolic support, synaptic regulation, and inflammatory signaling.
-
Human-Relevant Model : Human astrocyte properties and cellular heterogeneity are relevant to translational neuroscience and human disease research.
