Our data also indicate that MT1‐MMP endothelial targeting could be useful in other conditions that involve pathological IA, such as cancer (Ribatti & Djonov, 2012) and also bronchopulmonary dysplasia of the pre‐term lung, in light of the reported role of MT1‐MMP in postnatal lung expansion (De Paepe et al, 2017; Oblander et al, 2005). Here, MMP14 is linked to cancer.
