A role for fibrillar collagen deposition and the collagen internalization receptor endo180 in glioma invasion.

<h4>Background</h4>Glioblastoma multiforme (GBM, WHO grade IV) is the most common and most malignant of astrocytic brain tumors, and is associated with rapid invasion into neighboring tissue. In other tumor types it is well established that such invasion involves a complex interaction be...
