Effects of Placenta-Derived Mesenchymal Stem Cells on the Particulate Matter-Induced Damages in Human Middle Ear Epithelial Cells

Figure 4

Changes in mRNA expression levels of placenta-derived mesenchymal stem cells (PL-MSCs) after coculture with particulate matter- (PM-) treated human middle ear epithelial cells (HMEECs). The mRNA levels of TGFβ, VEGF, and PTGES were increased after coculture with PM-treated HMEECs (transforming growth factor beta (TGFβ), vascular endothelial growth factor (VEGF), and prostaglandin E synthase (PTGES)).
