We studied trophic effects of cholecystokinin (CCK) and calcitonin gene-related peptide (CGRP) on explanted cultures of ventral spinal cord from 13-14 old day rat embryo. There was a significant neurite promoting effect (NPE) in CCK-treated culture. The neuritic extension of ventral spinal cord exceeds control values 3.5-6.5 times. Otherwise, CGRP and NPE at any concentration. The possible mechanism of trophic effect of CCK on ventral spinal cord was briefly discussed. Our results may contribute to a therapeutic strategy for amyotrophic lateral sclerosis.
