We have been studying the response of neural crest cells from 56-h-old quail embryos to small, imposed d.c. electrical fields. These cells exhibit directed translocation or galvanotaxis towards the negative pole of fields as low as 7 mV/mm. With an average cell length of 60 µm, these cells respond to fields as low as 0.4 mV along their length. A significant change in the average cosine of the cellular translocation distribution can be detected as early as 7 min after field application for all… CONTINUE READING
