제목 Facile monitoring system of intracellular microRNA during adipogenesis via mechanical stimulus-induced exocytosis of liposomal probe
초록 Non-invasive investigation of miRNA expression in culture soup is particularly useful for monitoring of stem cell differentiation without photo-toxicity of living cells, especially when cell morphologies remain unchanged during differentiation. However, real-time detection of miRNA in culture soup is not recommended because of insufficient miRNA amounts in culture soup. In this study, we introduce facile method for real-time assessing intracellular miRNA in culture soup by using liposomal miRNA beacon (Lipo-mB) and mechanical stimulus-mediated exocytosis. Pipetting-harvest of culture soup induces exocytosis-secretion of fluorescence signal of Lipo-mB from cytoplasm into culture soup. Lipo-mB successfully monitor stem cell differentiation (adipogenesis) by sensing changes in miRNA expression from culture soup of living cells. Lipo-mB can be further developed as an accurate sensing system for analyzing subtle differences in genotype, even when changes in phenotype cannot be observed.
