Engulfment of apoptotic neurons by Cx3cr1-expressing microglia/macrophages in the injured cortex following CCI. A–E Representative confocal images for TUNEL (red, D)- and NeuN (purple, B)-stained coronal section of Cx3cr1^{EYFP−CreER/+} mice at 3 dpi. F–O Region of interest (ROI) showing Cx3cr1⁺ cells (green) containing TUNEL + cells (yellow arrowhead), NeuN + cells (white arrow), and TUNEL + /NeuN + cells (white arrowhead) in the peri-lesion cortex. Scale bar = 100 µm in A–E and 10 µm in F–O
