Retinal axons in Xenopus laevis recognise differences between tectal and diencephalic glial cells in vitro.
Explants of retina from Xenopus laevis were cultured on monolayers of tectal and diencephalic glial cells in order to determine whether the glia, normally encountered by optic nerve fibres as they grow to the optic tectum, can influence the growth of these neurons in any way. Explants of nasal retina produced prolific radial outgrowth patterns on both tectal and diencephalic monolayers. Explants of temporal retina produced similar outgrowth patterns on diencephalic glia, but on tectal glia the outgrowth was restricted and fibres were fasciculated in short, fat bundles.
