Isolation and culture of auditory cells from the goldfish (Carassius auratus).
Large numbers of hair cells and VIIIth nerve ganglion cells are obtained from the inner ears of adult goldfish by a combination of enzymatic and mechanical dissociation. Centrifugation of the dissociated tissue through a discontinuous density gradient produces one fraction enriched in hair cells and another enriched in nerve cells. The fraction of cells enriched in neurons can be put into cell culture and kept for a period of weeks. During that period, the neurons send out processes that can extend for millimeters. The morphology of these cultured neurons is similar to that of the goldfish auditory neurons in histological material.
