Unlike Sema3A, Sema3F and Sema3B do not induce VP. (A) Balb/c mice were injected with 30 μg/mL Sema3A or Sema3F (n = 9), and 1% Evans blue dye extravasation was quantitated. Data represent mean plus or minus SEM. (B) Balb/c mice were injected with 30 μg/mL Sema3A or Sema3B (n = 6). Data represent means plus or minus SEM.
