Unphosphorylated connexin 43 distribution in myometrium during term labour. (a) Antibody for unphosphorylated (serine 368) connexin 43 binds only to cells on the boundaries of the smooth muscle bundles (arrowhead) and to vascular endothelial cells (arrows) but not to smooth myocytes (Magnification ×10, Bar 100 micrometres). (b) At higher magnification, these cells show homogenous staining throughout the cell membrane, an oval shaped nucleus, elongated cell body and extended dendritic processes. (Magnification ×100, Bar 10 micrometres).
