Six Marker Immunohistochemistry Connexins on Astrocytes Predominantly in the Parenchyma in the Retina of a Middle Aged Rat.

<p>Cx26 (blue, A), Cx30 (red, B), Cx43 (green, C), Cx45 (pale brown, D) were colocalised (E) on GFAP positive-astrocytes (pale purple, F). Connexin heterogeneity in gap junction plaques are indicated as follows: Cx26⁺/Cx43⁺ (large arrows), Cx26⁺/Cx45⁺ (small arrows), Cx26⁺/Cx30⁺/Cx43⁺ (curved arrows), Cx26⁺/Cx43⁺/Cx45⁺ (arrowheads). Scale bar, 50 µm (A–F).
