Electron micrographs of collagen lamellae from WT and P2X7 −/− mice. (A) Lamellae are more numerous in WT than P2X7 −/− in the middle of the central stroma. Scale bar, 500 nm. (B) Mean lamellae thickness. A minimum of 34 orthogonal and perpendicular lamellae throughout the stroma were measured for each group. Data are presented as ± SEM. *P < 0.001; t-test.
