AldoC BAC-GFP transgenic mice as a reliable model for astrocyte identification and functional studies in the brain.

ABSTRACT: Astrocytes, the most abundant glial cell type in the central nervous system (CNS), are essential for maintaining neural homeostasis, forming gliovascular unit, and modulating synaptic function. However, commonly used astrocytic markers often display regional variability or lack strict specificity, limiting their reliability for consistently identifying astrocytes across brain regions. To address this limitation, we generated a novel transgenic mouse line (AldoC BAC-GFP) that expresses green fluorescent protein (GFP) under the control of the aldolase C (AldoC) promoter using modified bacterial artificial chromosome (BAC) technology. AldoC is an enzyme abundantly expressed in astrocytes. We confirmed that GFP-expressing cells in these mice co-express endogenous AldoC and are co-labeled with
