SOL-neuron material transfer in the postnatal mouse brain. (A) Schematic representation of regional distribution of nuclear and ribosomal reporter-positive neurons and reporter-positive Olig2⁺ oligodendrocyte-lineage cells at P5, P14, and P30. (B–F) Representative images showing Rpl10a-EGFP⁺ neurons (arrowheads) and Olig2⁺ oligodendrocyte-lineage cells in the cortex, hippocampal DG, striatum, and thalamus during postnatal development. (G and H) Quantification of Olig2⁺GFP⁺ oligodendrocyte-lineage cells and NeuN⁺GFP⁺ neurons in the postnatal brain of Sox10-Cre:Rpl10a-EGFP mice. All data are presented as mean ± SEM. Each circle represents an individual animal. Data are representative of three independent experiments. P values were determined by one-way ANOVA with Bonferroni post-hoc test. *, P < 0.05; ***, P < 0.001; ****, P < 0.0001. Scale bar: 500 µm for C; 100 µm for F; 50 µm for B, D, and E. A, amygdala; CP, caudate putamen; CC, corpus callosum; Cx, cortex; Hip, hippocampus; Hy, hypothalamus; Th, thalamus.
