Table 1.

Statistical amounts of hemichannels and gap junction channels in the case of 2 co-expressed connexins

	Double co-expression of Connexins
	Hemichannels	Gap junction channels
	2 homomeric 12 heteromeric	2 homomeric-homotypic 1 homomeric-heterotypic 24 heteromeric-homotypic 168 heteromeric-heterotypic
Total	14	195

These amounts consider that each association is possible independently on the connexin composition of hemichannels, and are indicated without considering that each channel can be in 2 different orientations
