Neuronotrophic factors (e.g. basic fibroblast growth factor, bFGF and nerve growth factor, NGF) have been demonstrated to respectively promote survival and neuritogenesis in cultures of dissociated adult rat spiral ganglia. Transforming growth factor beta (TGF beta 1) has been shown to modulate the response of cultured auditory neurons to bFGF through the induction of high affinity receptors for bFGF in the neurons. In this study, we show that TGF beta is expressed in situ by adult auditory neurons in response to traumatic injury (i.e. transection of the eighth cranial nerve). Based on these in vivo results and on the results from our previous in vitro studies, we propose that TFG beta 1 acts as an early autocrine signal involved in the response to injury by neurons of the peripheral auditor system.

Ante- and post-mortem MRI and detailed pathological examination were performed in a patient with a typical acute traumatic central cord syndrome (ATCCS) after a minor hyperextension injury to the neck who died 60 h later from heart failure. T2-weighted MRI showed a central hyperintense area at C3-4. There were disc protrusions, but no vertebral fracture or displacement. Histopathology disclosed severe axonal swelling and oedema in the dorsolateral fasciculi and, to a lesser degree, in the dorsal columns. In addition, an area of recent necrosis was found in the right anterior horn at C4-5. These findings suggest that the pathological hallmark of typical ATCCS is mechanical axonal disruption at a segmental level, but that more severe trauma may be accompanied by tissue destruction.

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 ▲]Detailed reference viewed: 19 (3 ULg)
