Measuring migration of individual cells

Yanyi Huang and colleagues at Peking University have developed a microfluidic-based assay to allow them to quantitatively measure single cell migration speeds.  Existing methods for determining cell migration are abundant, as the process is important for processes such as cancer metastasis, embryonic development and wound healing, but it is very difficult to distinguish between migrating and proliferating cells in current assays.

Using their migration assay, Huang and colleagues were able to show that HUVEC migration is epigenetically regulated:
