Cell migration and invasion

Cell migration and invasion


Cellular migration is a highly integrated, multi-stage process that plays an important role in the progression of various diseases, including cancer, atherosclerosis and arthritis. There are different types and definitions of cell migration.
Cellular invasion is related to and dependent on cell migration, except that cells do more than migrate. Invasive cells move through the extracellular matrix (ECM) in neighboring tissues in a process that involves extracellular matrix degradation and proteolysis.
We propose tests to study migration and cell invasion in two formats:
  • Boyden chamber assays consist of a cell culture insert tucked into the well of the cell culture plate. The cells are seeded in the insert and migrate through the pores of the membrane at the bottom thereof.
  • Gap closure assays create a defined area through which cells migrate. Cell migration can be monitored in real time by microscopy.
