Explants from the metencephalic region of 40-h chick embryo neural tubes containing the trigeminal (V) motor nucleus were cultured in appropriate target muscle-conditioned media (MCM) derived from chick, quail and rat embryos. Enhanced neuritic outgrowth was found only in the presence of chick MCM, indicating that this early, initial responsiveness to target-released materials within this system is species-specific.
