What makes cells migrate – and what can stop them

A team of scientists from the University of Konstanz has identified the PPM1F enzyme as essential for cell migration in both embryonic development and tumor cell invasion. The study found that increased levels of PPM1F enhance the invasive potential of cancer cells, while its absence impairs cell adhesion and migration.
