Cell Electrotaxis

Over the years, scientists have studied the way cells within organisms communicate. Electric signals play a crucial role in the development, growth and healing processes.

Additional Readings and Literature

Juno Biomedical, Inc. is built on years of research. The following is a list of papers that support the use of electrotaxis as a potential means of returning significant motor function to people who have experienced an ischemic stroke. Of most significance is the recent paper published by Feng and team earlier this year:
