Fig. 6.18
Bright-field TEM
image of a liver cell prepared
using chemical fixation,
embedding in epoxy resin,
and ultramicrotomy, showing
a triglyceride phase (
arrow
)
that has undergone
compression phenomena:
ridges and matter
displacement, resulting in
holes followed by folds in the
sectioning direction
(indicated by the
arrow
direction
). From this we
conclude that the softer phase
is poorly embedded
