Figure 9.

Coexpression of NG2 and α3β1 integrin at the pericyte-EC interface. Sections from healing wound tissue at 7 days after surgery were immunostained for NG2, α3 integrin subunit, and CD31. Cross section of a newly formed capillary reveals the investment of CD31-positive EC by NG2-positive pericytes (bottom panels). α3 integrin is also expressed in EC surrounded by NG2-expressing pericytes (top panels). Galectin-3 staining is also found in these blood vessels, but is not restricted to the vasculature (unpublished data). Scale bar, 20 μm.
