Partial purification and characterization of a neurite-promoting factor from the injured goldfish optic nerve.
We have partially purified and characterized a neurite-promoting factor derived from the injured goldfish optic nerve (ON). This factor is secreted into conditioned media (CM) by the injured, but not intact goldfish ON, and has potent outgrowth-promoting effects on neurons of the embryonic mammalian brain. Based on its elution properties on ion-exchange and gel-filtration chromatography, this factor appears to be an acidic protein of Mr ca. 26 kilodaltons (kDa) that is distinct from previously characterized growth factors with described effects on mammalian CNS neurons.
