Connexin43 expression during Xenopus development

Mech Dev. 2001 Oct;108(1-2):217-20. doi: 10.1016/s0925-4773(01)00490-7.


The spatio-temporal expression of connexin43 in Xenopus laevis embryos was studied by in situ hybridization. Cx43 expression is first detected at stage 25 in the developing eye. In stage 32, expression was found in the margin of the lens placode, the cement gland, notochord, and in stage 37 in the branchial arches. Early limb buds show strong expression of Cx43 distally while later on expression is confined to sites of precartilage condensation.
