The depletion by neutralization or immunoprecipitation of VEGF, HGF or zonulin in glioma C6 CMwas not sufficient to eliminate ReNcells CX transmigration, thus indicating that no one singlefactor is responsible for this process and that instead the concomitant participation of all of themcontributes to NSC transmigration. The gene discussed is VEGFA; the disease is glioma.
