Invadopodia Detection and Gelatin Degradation Assay
Author:  Begoña Díaz, date: 12/20/2013, view: 20900, Q&A: 0
This protocol is designed to quantify invadopodia formation and activity. Invadopodia are protrusive structures elaborated by cancer cells that mediate cell attachment and remodeling of the extracellular matrix. These structures contribute to the ...
