...Herein, for the first time, we identified 11 natural compounds from medicinal plants with both excellent proliferative and anti-senescence abilities in MSCs. The qPCR analysis indicated underlying mechanisms associated with fibroblast growth factor, transforming growth factor, Wnt/β-catenin and leukemia-induced factor in proliferation; the reactive oxygen species production, mitochondrial dysfunction autophagy and proteostasis are involved in cells senescence-related mechanism. Phytochemicals are demonstrated as novel therapeutic candidates with promising effects in both stimulating proliferation and retarding replicative senescence of stem cells with high safety.
