One classic “artifact” is the loss of fat from liver tissue obtained from a patient with fatty liver masson’s trichrome stain (hematoxylin, acid fuchsin, and neurofibrils of neurons and granules in enteroendocrine cells these structures are stained black whereas other tissue components may take on a faint gray background stain. In addition and similar as with the h&e staining, masson trichrome stained sections also reveal adipose tissue, the variation in muscle fiber diameters, the presence of small or rounded fibers (de-/regeneration) as well as centralized nuclei (indicative of regeneration.

Masson’s trichrome-stained liver tissue sections exhibited prominent restoration of liver function the fibrous materials were entirely absent from the ecm and there were no signs of lipid droplets ( fig 4e . Hematoxylin-eosin and masson trichrome staining were performed on the liver tissue hepatic fibrosis stage was determined by a fellowship-trained liver pathologist (ad, 1 year of experience) by using the 0–4 batts-ludwig staging system as well as the 0–6 ishak staging system ( 13 , 14 . (masson trichrome and silver staining are frequently used in pathology to determine if connective tissue has proliferated--a sign of damage and attempted repair--in the liver, kidney and lung) back to top.
The first slide, a normal liver tissue stained with masson’s trichrome showed single layered well defined hepatocytes with nucleus stained black, cytoplasm and muscle stained red the second slide stained with masson’s indicates liver cirrhosis. Liver tissue sections sampled from different groups were stained with masson-trichrome to measure collagen accumulation and to score fibrosis (fig1) the degree of liver fibrosis was decreased in animals treated with rhbmp-7 in a time dependent manner. Diagnostic evaluation of liver tissue is largely based on a thorough examination of sections stained with hematoxylin and eosin (h&e) masson's trichrome stain is among the most common special stains applied to liver specimens the stain imparts a blue color to collagen against a red background of hepatocytes and other structures. In addition, hepatic sections from polluted area fishes showed more fibrotic changes and collagen deposition by hematoxylin-eosin staining and masson’s trichrome staining, respectively, compared to samples taken from the reference area.
These sections were stained with h&e in order to observe the structure of the liver lobule, and were also stained by masson's trichrome method and ishii and ishii's silver impregnation method to visualize the connective tissue of the liver.
