CXCR2 and CXCR4 levels were higher in the migrated EPCs induced by MSCs. (a) Representative images of migrated EPCs. The migration capacity of EPCs was observed using a Transwell culture system. Migrated EPCs were stained with DAPI. Scale bar, 50 μm. The amount of migrated EPCs was quantified and presented as a bar graph (n = 3; ∗∗p < 0.01). (b) Changes of protein expressions of CXCR2 and CXCR4 after blocking CXCR2 or CXCR4. After migration, EPCs were collected and subjected to western blot. BCM: basic culture medium; MSC-CM: conditioned media of mesenchymal stem cells.
