Fig. 6

Model for how potassium channels and gap junction channels may interact in vivo to determine skeletal patterning. Top: Changes in potassium ion concentration are readily propagated to coupled SPCs via Cx43-GJIC. This activates an unknown voltage-sensitive effector in SPCs, which initiates a cascade that impinges on suppression of evx1 transcription. Joint formation is disfavored. Bottom: Alternatively, when Cx43-GJIC is attenuated changes in ion concentration are not propagated. The voltage-sensitive effector is not activated, permitting evx1 transcription. Joint formation is favored. Created in BioRender. Seaver, A. (2025) https://BioRender.com/4p381ok.
