Age-Related Features of the Response of the Liver and Stem Cells during Modeling of Liver Cirrhosis
We studied the age-related characteristics of the response of stem cells and liver in male Wistar rats to administration of carbon tetrachloride (CCl 4 ) and ethanol. It was shown that modeling of liver cirrhosis caused inflammation, fibrosis, damage to sinusoidal capillaries, necrosis, and disturba...

Summary: | We studied the age-related characteristics of the response of stem cells and liver in male Wistar rats to administration of carbon tetrachloride (CCl

) and ethanol. It was shown that modeling of liver cirrhosis caused inflammation, fibrosis, damage to sinusoidal capillaries, necrosis, and disturbances in the functional activity of hepatocytes in young rats. These processes were accompanied by mobilization of profibrotic mesenchymal stem cells (MSC), proinflammatory hematopoietic stem cells (HSC) and lymphocytes (CD45

) from the bone marrow into the blood and migration to the liver. On the other hand, the number of hepatocyte precursors expressing Sox9 (cells of Hering’s canal), immature cholangiocytes, Ito cells, oval cells, and endothelial cells of the liver sinusoids) sharply increased in the liver. In young rats, mobilization and migration of MSC, HSC, and hepatocyte precursors against the background of liver cirrhosis were more intensive than in old animals. The higher resistance of old rats to exposure is associated with age-related changes in the niches as well as in mobilization and migration of cells. |
