1:Serial section
TEM of S1 acinus. Total depth of 2.2 micron of S1 acinus surveyed by
serial section TEM. Twenty-two 100 nm thin sections sequentially cut and imaged
by TEM. Images were overlaid with ImageJ
(https://imagej.nih.gov/ij/). Serial sectioning provided 3-dimensional
view across middle of an acinus, demonstrating lack of apical polarity and
high-lighting the spot-like adhesion points on lateral cell surfaces.
