The targeted migration of neural progenitor cells (NPCs) towards brain injuries is mediated by chemokines, such as stromal cellVderived factor-1 (SDF-1). It is thus hypothesize that the transplantation of NPCs with an elevated SDF-1 gradient leads to stronger migration to the tumor site, which may cause a different growing pattern and morphology of the tumor. The present study demonstrates that combinative treatment of NPC with SDF-1 rendered tumors exhibit rapid growth with sever hemorrhage. The finding identified an important role of NPCs facilitated by SDF-1 in tumor expansion.
