Amniotic Mesenchymal Stem Cells Can Enhance Angiogenic Capacity via MMPs In Vitro and In Vivo

Figure 5

Inhibitory effect of MMPs in HUVEC tube formation under serum-free 3D fibrin matrices. HUVEC-sprouting had been inhibited significantly across all timepoints (a–r). Microscopic view is . The length of HUVEC-sprouting and average EC vessel area were decreased remarkably (s–x). There was no significant difference among three groups.
