title: Chick embryo spinal cord neurons synthesize a transferrin-like myotrophic protein.
abstract: Highly enriched cultures of chick embryo spinal cord neurons synthesize and secrete a protein which is immunoprecipitable by anti-ovotransferrin. Ovotransferrin, an iron-binding glycoprotein of Mr 80 000, is also shown to stimulate in vitro myogenesis of cultured chick embryo myotubes as measured by saturable dose-dependent increase in acetylcholine receptors. This effect is probably dependent on ovotransferrin's ability to donate iron to the cells. In many respects ovotransferrin is similar to 'sciatin', a myotrophic protein isolated from chicken sciatic nerves.
