To study the expression pattern of innexins in the male worm, we crossed innexin reporter strains (Altun et al., 2009) with him-5(e1490) strains and analyzed GFP expression using a compound microscope. As describe in the table, innexins are expressed in different tissues and cells of the male worm. These results will be compared to the male connectome project where a lot of gap junctions have been observed in the nervous system.
