  MSC mediate numerous therapeutic effects by promoting repair directly via differentiation into critical cell types or indirectly through the secretion of a broad spectrum of soluble factors with diverse paracrine activities. However, recent discoveries indicate that MSC are sensitive to endogenous and exogenous stressors and many diseaserelated interventions can result in Therapy-Induced Senescence (TIS) in MSC. Here, we provide a detailed analysis of changes in secretory factors that occur under conditions of bleomycin treatment that triggers genotoxic stressinduced senescence of Human Adipose-Derived Stem Cells (hADSCs). The bleomycin treatment considerably alters the composition of hADSCs secretome. Our data reveal the novel unique composition of Senescence Messaging Secretome (SMS) of hADSCs and suggest that this SMS might critically influence genotoxic drug-based or MSC combinati.. View More»
