Isolated adult mouse microglia have a low proliferative capacity in vitro
Representative fluorescent images of microglial cultures following the addition of Edu for 48 h (A). White arrowheads represent PU.1 positive microglia, whilst white arrows represent PU.1+ Edu+, dividing microglia. Red arrowheads represent PU.1- cells, whilst red arrows represent PU.1- Edu+ dividing non-microglial cells, which are largely pericytes. Scale bar, 50 μm. Average percentage of Edu+ microglia (PU.1+) per case, n = 6 adult mouse brain isolations (B). All data are plotted as mean ± SEM.
