text: Chronic overuse of common pharmaceuticals, e.g. acetaminophen (paracetamol),
often leads to the development of acute liver failure (ALF). This study aimed
to elucidate the effect of cultured mesenchymal stem cells (MSCs) proteome on
the onset of liver damage and regeneration dynamics in animals with ALF induced
by acetaminophen, to test the liver protective efficacy of MSCs proteome depending
on the oxygen tension in cell culture, and to blueprint protein components responsible
for the effect. Protein compositions prepared from MSCs cultured in mild hypoxic
(5% and 10% O2) and normal (21% O2) conditions were used to treat ALF induced
in mice by injection of acetaminophen. To test the effect of reduced oxygen tension
in cell culture on resulting MSCs proteome content we applied a combination of
high performance liquid chromatography and mass-spectrometry (LC–MS/MS) for the
identification of proteins in lysates of MSCs cultured at different O2 levels.
The treatment of acetaminophen-administered animals with proteins released from
cultured MSCs resulted in the inhibition of inflammatory reactions in damaged
liver; the area of hepatocyte necrosis being reduced in the first 24 h. Compositions
obtained from MSCs cultured at lower O2 level were shown to be more potent than
a composition prepared from normoxic cells. A comparative characterization of
protein pattern and identification of individual components done by a cytokine
assay and proteomics analysis of protein compositions revealed that even moderate
hypoxia produces discrete changes in the expression of various subsets of proteins
responsible for intracellular respiration and cell signaling. The application
of proteins prepared from MSCs grown in vitro at reduced oxygen tension significantly
accelerates healing process in damaged liver tissue. The proteomics data obtained
for different preparations offer new information about the potential candidates
in the MSCs protein repertoire sensitive to oxygen tension in culture medium,
which can be involved in the generalized mechanisms the cells use to respond to
acute liver failure.
