摘要

Mammalian central nervous system (CNS) neurons have negligible posttraumatic regenerative capacity while the nerves of lower vertebrates, as well as the pheripheral nervous system (PNS) of mammals regenerate spontaneously after injury. We found that application of soluble substances derived from growing nerves and of newborn rabbit optic nerves (in the form of conditioned media) to injured adult rabbit optic nerves resulted in alterations in neurons and their resident glial cells. In the course of our studies under this support, we succeeded to identify two activities within the active conditioned media derived from regenerating fish optic nerve and to purify a third molecular constituent, such as apolipoprotein-A-I. The two activities are an astrocyte-activating factor and an oligodendrocyte inhibitory factor. Lab animals; Rabbits; Fish-Carp; CNS; RA II; Mammals; Nervous systems; Neurons; Regeneration. (jg)
