Remodeling of the gross morphology of choroid plexus epithelial cells during aging. A Representative TEM images of choroid plexus epithelial cells at 2, 8 and 20 months old (m.o.). Yellow lines indicate horizontal and vertical cellular axes. Quantification of cell axis ratio (B) and cell profile area (C) averaged per cell. n = 30 cells per animal, 3 animals per age; black dashed line: median; Kruskal–Wallis; *p < 0.05, **p < 0.01. Scale bar: 2 µm
