Fig. 6From: Exosomal miR-17-5p from human embryonic stem cells prevents pulmonary fibrosis by targeting thrombospondin-2The mechanism of hESC-exo protects against BLM-induced pulmonary fibrosis. miR-17-5p was delivered by hESC-exo into recipient cells like AECs to regulate the mRNA transcription of Thbs2 in nucleus, resulting in the decreased translation of Thbs2 in the cytoplasm. Downstream fibrosis-related proteins like α-SMA, Fn, and Collagen I were downregulated due to the inhibited Thbs2, subsequentlyBack to article page
