Short-term infusion of BMP4 during demyelination increases the proliferation of OPCs, microglia and astrocytes. A–D. Immunostaining and quantification of the density of BrdU⁺Olig2⁺, BrdU⁺IBA1⁺, and BrdU⁺GFAP⁺ cells in the CC after 5 d of either vehicle or BMP4 infusion. Arrows indicate double-positive cells. n = 4–5 animals per group. *p < 0.05. Scale bar, 50 μm.
