Rh-CSF1 Attenuates Oxidative Stress and Neuronal Apoptosis via the CSF1R/PLCG2/PKA/UCP2 Signaling Pathway in a Rat Model of Neonatal HIE

Figure 3

Immunofluorescence staining of CSF1R and CSF1 with NeuN in the brain at 48 h after HI. (a) Representative microphotographs of CSF1R or CSF1 with NeuN staining in the ipsilateral cortex of the sham, HI+vehicle, and HI+rh-CSF1 groups. (b) Quantitative analysis of CSF1R-positive NeuN cells in the ipsilateral cortex at 48 h after HI. (c) Quantitative analysis of CSF1-positive NeuN cells in the ipsilateral cortex at 48 h after HI. Green indicated CSF1R- or CSF1-positive staining, red indicated NeuN-positive neuron staining, and blue indicated DAPI-positive nuclear staining. Merge showed the colocalization of CSF1R or CSF1 with neurons. vs sham; # vs vehicle; ; . The upper right panel of the brain slice indicates the location for staining analysis (small blue box).
