Effect of α2M* on FGF-2–induced endothelial tubule formation on Matrigel.
FBHE cells were plated on Matrigel and incubated at 37°C for 96 hours in the absence of FGF-2 (A), 0.625 ng/mL FGF-2 (B), and 0.625 ng/mL FGF-2 incubated with 0.5 mg/mL α2M* (C). Photographs are representative fields from 4 experiments at 25 × (A) or 50 × (B,C) magnification.
