Effect of α2M* on FGF-2–induced endothelial tubule formation on collagen gel.
HUVECs were plated on collagen type I gels and incubated at 37°C for 24 hours in the absence of FGF-2 (A), 100 ng/mL FGF-2 (B), and 100 ng/mL FGF-2 incubated with 0.5 mg/mL α2M* (C). Photographs are representative fields at 10 × magnification.
