.... The electrical signal across the epithelium could serve as a coordinating cue, orienting and polarizing enterocytes. Here, we show that applying a physiological electric field to intestinal epithelial cells, to mimic the natural electric field created by the transepithelial potential difference, polarized...

... of the tube after 1-2 months. This is expected, because adult mammalian spinal-cord axons do not normally regenerate. In the presence of an electric field, however, significant regenerative axonal growth (green lines) was stimulated. Axons were attracted towards the tube and penetrated several millimetres...

... on the skin and are used to differentiate malignant from benign breast tumours. Could the electrical signals play a role in metastasis by promoting tumour cell migration? We report that electric fields stimulate and direct migration of human breast cancer cells. Importantly, these effects were more...

...Ann M. Rajnicek; Louise E. Foubister; Colin D. McCaig Although it is known that neuronal growth cones migrate towards the cathode of an applied direct current (DC) electric field (EF), resembling the EF present in the developing nervous system, the underlying mechanism remains unclear. Here, we...

...Ann M. Rajnicek; Louise E. Foubister; Colin D. McCaig Electric fields (EFs) resembling those in the developing and regenerating nervous systems steer growth cones towards the cathode. Requirements for actin microfilaments, microtubules and their interactions during EF growth cone steering have been...

... electric fields induce directional cell migration in a wide variety of cells. Here we show that electric fields of 300 mV/mm induce robust Golgi polarization and directional cell migration in CHO cells. Asymmetric Src and PI 3-kinase signalling as well as actin polymerization are essential for electric...

...Bing Song; Min Zhao; John Forrester; Colin McCaig Biological roles for naturally occurring, extracellular physiological electric fields have been proposed over the past century. However, in the molecular era, many biologists presume that electric fields have little physiological relevance because...
