Abstract (original English)
Adipose-derived stem cells (ASCs) can shift toward proinflammatory and fibrotic phenotypes, but factors triggering this transition are not fully understood. This study aimed to elucidate the impact of exposure to regulated cell death environments on the fibroinflammatory potential of surviving subcutaneous ASCs (sub-ASCs). Surviving sub-ASCs were characterized by transcriptional analysis of genes associated with inflammation and extracellular matrix remodeling. Phenotypical markers of fibroinflammatory progenitor cells were monitored by immunoblotting and flow cytometry. We determined post-translational modifications (PTMs) of histone proteins by immunoblotting and mass spectrometry, including individual and combinatorial histone marks. Four days after transient exposure to serum starvation- or tumor necrosis factor-alpha (TNFα)-induced cell death, surviving sub-ASCs cultured under hypoxic proliferative conditions showed elevated mRNA levels of inflammatory mediators, fibrillar collagens, matricellular proteins, and cytoskeletal components. This fibroinflammatory transcriptional activation was accompanied by decreased expression of fibroinflammatory progenitor cell markers. Surviving sub-ASCs exhibited variations in histone methylation marks associated with transcriptional regulation. Inhibiting calcium-dependent μ- and m-calpains during TNFα-induced cell death increased histon
