Figure 6: (a) A histological view of the yellow box in Figure 5(a). The lengths of three intervening parts are measured (yellow arrows and yellow figures). A scale bar is shown at the bottom. Height and lengths of intervening parts: The protruding parts between crypts have a shape resembling an ellipse (as indicated by the yellow dotted lined), allowing the major axis (yellow line) of the ellipse to be drawn. The vertical line representing the major axis was defined as the height of the intervening part. The width of the widest part less than 100  m from the top of the intervening parts was adopted as the length of the intervening parts. (b) A histological view of the yellow box in Figure 5(b). The lengths of three intervening parts are indicated (yellow arrows and yellow figures). A scale bar is shown at the bottom. (c) A histological view of the yellow box in Figure 5(c). The lengths of three intervening parts are indicated (yellow arrows and yellow figures). A scale bar is shown at the bottom.
