a–f, Enhanced surface shape information. a,
Standard FFPE-H&E histology of human kidney with proteinaceous casts filling
some tubules. b, Same kidney imaged with MUSE, and pseudocoloured
for clarity. Casts can be seen as cylindrical structures, including one that was
dislodged from its original site. c, H&E Schwannoma. Swirling
nature of this tumor can be appreciated. d, MUSE of same specimen,
in which the 3D organization of the tumor can be appreciated. e,
Seromucinous ovarian carcinoma, H&E. Carcinoma-lined tufts surround
fibrovascular cores are visible. f, Same tumor imaged with MUSE,
revealing cauliflower floret-like clumps of malignant epithelial cells outside
fibrovascular cores. A window into a core is visible, top right.
g–j, Broader colour gamut reveals novel tissue contrast.
g,h, Corresponding regions of normal human stomach fundus and
i,j, porcine renal pelvis are shown, with MUSE specimens
stained using rhodamine and Hoechst. g, Conventional FFPE H&E;
h, MUSE, fluorescence image from a similar region. The chief
(brown) and parietal cells (orange) are much easier to distinguish in the
fluorescence MUSE image. i, Fixed porcine renal tissue, H&E;
j, corresponding region, MUSE fluorescence mode. Stromal
features, some identified by number, are easier to distinguish in the MUSE image
vs. H&E. Scale bar = 100 μm.
