Figure 7. Summary scheme of how KCa3.1 and TRPC3 channels cooperate with each other in order to support migration.
KCa3.1 channels provide electrochemical driving force for Ca2+ entry via TRPC3 channels. [Ca2+]i in turn maintains activity of KCa3.1 channels and, among others, activates calpain thereby promoting deadhesion of migrating stellate cells.
