Figure Lengend Snippet: Connexin 43 and Dlg1 are located in the cytoplasm of cells during wound closure. a Confocal microscopy images over time showing unwounded control cells and images taken at 0, 4, 8, 16 and 24 h post-wounding of the leading edge of a scrape wound in a confluent HaCaT cell culture. In the merged images, Cx43 is shown in magenta and Dlg1 is shown in green. Blue staining (DAPI) shows the nuclei. Dotted lines indicate the edge of the wounds. White arrowheads indicate examples of gap junction plaques in the Cx43 images. White asterisks indicate examples of Dlg1 at the plasma membrane and yellow asterisks indicate examples of cytoplasmic Dlg1 in the Dlg1 images. In the merged and enlarged merged images, white arrows indicate examples of co-location of Cx43 and Dlg1 on the plasma membrane. Yellow arrows indicate examples of intracellular co-location of Cx43 and Dlg1. Scale bar = 20 µm. b Graph of percentage co-localisation of Cx43 with Dlg1 (Manders coefficient) at 0, 8 and 16 h post-scrape wounding. c Graph of percentage co-localisation of Dlg1 with Cx43 (Manders coefficient) at 0, 8 and 16 h post-scrape wounding. * p < 0.05, ns, not significant. Calculations were carried out across five images at each time point. Each image had an average of 23 cells
Article Snippet: To generate a plasmid containing the sequence of human Cx43 with a C-terminal mCherry tag, we designed primers to clone human Cx43 into the pmCherry-N1 vector (Clontech) (primer sequences shown in Table ).
