Fig. 2

a Representative TEM images of choroid plexus epithelial cells at different ages. Asterisks indicate microvilli; arrow: tight junction; arrowhead: mitochondria. Quantification of cross-sectional cell area (b), cell axis ratio (c), and microvilli length (d). Representative high magnification TEM images of microvilli (e) and tight junctions (f) from all age groups, n = 3 (each dot represents the average of seven images per animal). 1 M; turquoise, 3 M; green, 6 M; orange, 12 M; red, 18 M; purple, 24 M; grey. Data are presented as mean ± SEM, and statistical significance was tested with the Kruskal-Wallis test followed by Dunn’s multiple comparisons test. Non-significance is not illustrated for clarity. Scale bar 5 µm (a), 1 µm (e), 2 µm (f). Source data are provided as a Source Data file.
