LCT

aldehyde-fuchsin staining high power
LCD slice
HE Staining lower power
fibroblast
Most numerous, and
only nuclei can be
seen, which are
ovoid, large with fine
chromatin granules
and anucleolus.
macrophage

A. 疏松结缔组织铺片，箭示2个巨噬细胞，胞质
中含吞噬的染料颗粒 醛-复红-伊红染色 高倍
round, oval or irregular cells with clearcut outline, red
cytoplasm and small dark nucleus
Adipose HE staining lower power
Adipose cells are filled with fat and shape of the cell is nearly
spherical. Nucleus is flattened and pressed against the cell membrane
giving a signet ring appearance
Adipose cell
