Endogenous Ion Dynamics in Cell Motility and Tissue Regeneration

Directional cell migration is an essential process, including regeneration of tissues, wound healing, and embryonic development. Cells achieve persistent directional migration by polarizing the spatiotemporal components involved in the morphological polarity. Ion transporter proteins situated at the cell membrane generates small electric fields that can induce directional cell motility. Besides them, externally applied direct current electric fields induce similar kind of responses as cell orientation and directional migration. However, the bioelectric mechanisms that lead to cellular directedness are poorly understood. Therefore, understanding the bioelectric signaling cues can serve as a powerful modality in controlling the cell behaviour, which can contribute additional insights for development and regeneration.
