Density of oligodendrocyte types within P10, P20, and P60 CTX (GM). a Heatmaps of the density of cells for each oligodendrocyte type in P10 CTX (GM), normalized to the highest cell density per section. The scale bar is 500 μm. b Same as (a) for P20 CTX. c Same as (a) for P60 CTX. d Top: the mean normalized occurrences of P10 oligodendrocyte populations in primary somatosensory cortex (S1), primary motor cortex (M1), secondary motor cortex (M2), cingulate cortex area1 (Cg1), and cingulate cortex area2 (Cg2) (n = 4 P10 tissue sections). Bottom: the mean cortical depth profiles with the transparent shades representing the standard error of the mean. Dashed lines denote layers I, II/III, IV, V, and VI. The X-axis (top) and Y-axis (bottom) respectively represent the occurrences after smoothening non-binned data with a kernel statistical comparisons were determined using ANOVA and post hoc test with Tukey correction (*p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001). e Same as (d) for P20 CTX (n = 6 P20 tissue sections). f Same as (d) for P60 CTX (n = 6 P60 tissue sections)
