To study the interactions between neurons of known transmitter phenotype and non‐neuronal cells of glial or fibroblastic origin, serotonergic (5‐HT) neurons were tested for their strength of adhesion and neurite outgrowth patterns on substrates of astrocytes or fibroblasts using a cell adhesion assay for transmitter‐identified neurons, and morphometry of immunocytochemically stained neurons in dissociated cell cultures. Both the strength of adhesion and the rate and complexity of neurite outgrowth by 5‐HT neurons were significantly greater on substrates of astrocytes compared to fibroblasts. These results provide evidence that 5‐HT neurons can interact selectively with glia via cell surface determinants, and that this process may be important for the development of complex (dendrite‐like) neuritic arbors. The methods developed in this study will be useful for future studies of interactions between transmitter‐identified neurons and glial cells during ontogeny of the embryonic brain.
