Photomicrograph of CAM: inhibition by HK D5 and HKa.

Few vessels are seen when CAM is incubated with a disk containing control (PBS). When the CAM is incubated with a disk containing GST (0.2 μM), no differences from control are observed (not shown). Many new vessels are seen with stimulation by FGF₂. When the CAM is incubated with FGF2 and GST (0.2 μM), no differences from FGF2 alone are observed. The formation of new vessels by FGF2 + GST-D5 (0.2 μM) is markedly decreased compared to FGF2 alone and does not differ from control (original magnification × 40).
