Pgrmc1 and Pgr (PR) expression in rat brain glia and neurons by immunocytochemistry. (A) Neuronal Pgrmc1 and Pgr expression in adult rat hippocampus was equivalent in the hippocampus CA1, CA3, and dentate gyrus (DG) layers. In contrast, neuronal Pgr expression was lower DG vs. CA1 and CA3 layers. (B) Astrocyte Pgrmc1 in DG molecular layer co-stained with GFAP. Arrowheads point to co-labeled astrocytes. (C) Microglial Pgrmc1 in DG molecular layer co-stained with IBA1. Arrowheads point to co-labeled microglia. (D) Astrocyte Pgrmc1 in primary cultures from cerebral cortex co-stained with GFAP. (E) Microglial Pgrmc1 in primary cultures co-stained with CD11b. Scale bars, 20 μm. Modified from Bali et al. (2012) and Bali et al. (2013).
