干细胞信号传导和治疗中的旁分泌/自分泌机制:
# y! i$ L2 W# v9 z/ H. x/ J4 g- NASCs release biologically active substances in a temporal and spatial manner in response to specific environmental stimuli such as ischemia. These factors influence the microenvironment by exerting paracrine actions on different cell types, leading to tissue protection, repair, and regeneration. The putative factors may also exert autocrine actions modulating the biology of stem cells including self-renewal and proliferation.
