LPS treatment does not modify the distribution of microglial cell and cell viability.

<p><b>A, B</b>: Distribution of microglial cells in control (A, CT) and LPS-treated (B, LPS) retinal explants. Left panels display microglial cells labeled with anti-CD45 antibody, while right panels also show cell nuclei stained with Hoechst. The distribution of microglia in LPS-treated explants is similar to that of untreated explants. Representative images of 3 different explants per condition. Scale bar, 50 μm. <b>C</b>: Bar graph showing that LPS treatment has no significant effect on cell viability in retinal explants. Bars represent mean values ± SEM of 5 explants).
