Highly enriched cultures of Schwann cells were obtained from adult rat dorsal root ganglia and implanted (5 x 10(5) -9 x 10(5) cells) in the spinal cord of syngenic adult rats at the site of an acute compression lesion produced by a subdural inflatable microballoon. These autografts survived and invaded the host tissue, reducing central cavitation and astrocytic gliosis. They dramatically promoted ingrowth of axons, the majority of which appeared to come from the dorsal roots as judged by their neuropeptide content. Invasion of the transplants by descending, e.g. aminergic fibers, was negligible at survival times of up to 4 months. Nonetheless, autologous Schwann cells, which are readily available in the host, represent a promising material for grafts into the injured spinal cord. [less ▲]

In Meniere's disease, the increase of extracellular potassium concentration in the perilymph is thought to play a key role in determining the progressive loss of cochlear hair cells. In this paper, we describe a serum-free culture preparation of hair cells from 5 day-old rat and report the release by the cochlea, in response to an increase of extracellular potassium concentration, of a cytotoxic activity active on hair cells and auditory neurons. The toxic activity is associated with low molecular weight (less than 10,000 Dalton) molecule(s) as revealed by ultrafiltration. Morphological studies performed on the organ of Corti incubated during 24 h in the presence of the cochlea-derived toxic activity (CTA), show that this factor is toxic for hair cells and not for supporting or surrounding cells. The release of CTA occurs both in the spiral ganglion and in the organ of Corti. We suggest that this cochlea-derived toxic activity may play an important role in the pathophysiology of the hearing loss that occurs during the progression of Meniere's disease. [less ▲]

In the developing inner ear, the existence of a neuronal death and of a peripheral target-derived trophic effect on cochleovestibular neurons has been documented. Using cultures of rat cochleovestibular neurons, we show that the E12 otic vesicle releases a factor promoting the survival and the neuritogenesis of these neurons, and that this effect is mimicked by NGF. The effect of the optic vesicle conditioned medium (OVCM) on cochleovestibular neurons is suppressed by anti-NGF antibodies. OVCM is neuronotrophic for NGF-sensitive sympathetic neurons, an effect that is also suppressed by anti-NGF antibodies, further demonstrating the presence of biologically active nerve growth factor.
