Figure 7. lncRNA GAS5 in exosomes from hUC-MSCs-CM alleviating EMT through Wnt/β-catenin pathway. (A) Exosomes from hUC-MSCs could suppress the Wnt/β-catenin pathway in HG HPMCs by Western Blot. (B) Statistical results of Wnt/β-catenin pathway changes after HG and hUC-MSCs/hUC-MSCs exosomes treatment. (C) The expression of Wnt3a and β-catenin was detected by real-time PCR. (DF) Exosomes from hUC-MSCs could suppress the Wnt/β-catenin pathway in HG HPMCs by transferring lncRNA GAS5 to HPMCs. (G) After transfection with β-catenin vector, alleviated EMT all reversed in HG+ lncRNA GAS5 group by Western Blot. (H) Statistical results of EMT changes after HG and transfection with lncRNA GAS5 and β-catenin vector. (I) The expression of EMT markers was detected by real-time PCR in HPMCs. (J) Exosomes secreted from hUC-MSCs alleviated the transfer into the nucleus of β-catenin in HG-treated HPMCs.
