Height of cell edges of brain tumour cells indicative of invasion?

What is it about?

Highly invasive brain tumours (Glioblastoma multiforme, GBM) have a very poor prognosis for patients with the condition (median survival 14.2 months). Using an atomic force microscope, we have shown that the leading edges (lamellipodia) of these moving brain tumour cells are significantly higher than normal (non-cancerous) brain cells. The edges of GBM cells are also higher than those of low-grade glioma cells.

Why is it important?

These results indicate that the heights at the leading-edges of brain cells might be related to invasion potential and therefore may provide new insights for monitoring and controlling cellular invasion in brain tumours.
