Inhibition of bFGF and VEGF induced capillary morphogenesis of ECs in 3D type I collagen matrix. The samples shown in the upper panels (A-E) were treated with anti-MHC class II mAbs, whereas those in the lower panels (F-J) with anti-α_vβ₃ integrin antibodies. Cross sections were stained with acidified eosin as described in methods. Magnification, 100×. Bar, 200 μM.
