We investigated the developmental expression and cellular resolution of connexin32 and 43 mRNA in the rat brain using in situ hybridization. Utilizing 35S-labelled probes, in situ hybridization was performed on sections of embryonic day 20 and postnatal days 3, 10, 15, 30 and adult brain. Connexin32 mRNA was first detected in brainstem nuclei at postnatal day 3 and in the midbrain at postnatal day 15. The level of this message continued to increase to postnatal day 30 where the level of message reached a plateau or slightly decreased by adulthood. The distribution of signal included the medial vestibular nucleus, dorsal ...
