Slices of foetal spinal cords in culture were used to establish possible trophic effects of alpha-melanocyte stimulating hormone (alpha-MSH) and a fragment of the adrenocorticotropic hormone (ACTH4-10) on the outgrowth of neurites from spinal neurons. The spinal cord slices were treated with peptides over a wide concentration range. Using monoclonal antibodies against (subunits of) neurofilament followed by immunofluorescence, we could show that the extension consisted mainly of axons. After 5 and 7 days, outgrowth was quantified with 2 different techniques, namely by visual scoring under phase contrast and by means of an ELISA for neurofilament protein. Both methods yielded the same dose-response profile. Both alpha-MSH and ACTH4-10 stimulated the formation of neurites in a dose-dependent manner, with a maximal stimulatory effect at 0.001-0.01 nM (ACTH4-10) or 0.1-1.0 nM (alpha-MSH). The maximal effect of the peptides was 30-40% compared to controls. We conclude that alpha-MSH and ACTH4-10 stimulate axonal outgrowth from foetal spinal cord slices in vitro in a dose-dependent way.
