SOLUTION: no

PROBLEM: Question: Does nifedipine interfere with migration of vascular smooth muscle cells via inhibition of Pyk2-Src axis?
Answer: These data suggest that nifedipine interferes with VSMC migration via inhibition of the Pyk2-Src axis and inhibition of actin remodeling processes, including membrane ruffling and lamellipodium formation.

SOLUTION:
yes
