Purified exosome product enhances chondrocyte survival and regeneration by modulating inflammation and promoting chondrogenesis.
Regenerative medicine(2023)
摘要
This study was to detect the effects of purified exosome product (PEP) on C28/I2 cells and chondrocytes derived from osteoarthritis patients. Cell viability and apoptosis assays were used to detect the effect of PEP on cells. qRT-PCR and cell fluorescence assays were used to investigate the potential mechanism of PEP on cell chondrogenesis. PEP was internalized by cells at a fast rate and enhanced cellular proliferation and migration while attenuating apoptosis. These findings reflect the fact that PEP can increase the expression of and reduce the expression of // and . This study suggests an innovative strategy for chondrogenesis that could be applied to osteoarthritis repair in the future.
