An object of the present invention is to provide a highly safe transcellular differentiation promoter having neuronal cell differentiation promoting activity. A neuronal differentiation promoter comprising a peptide represented by Gly-Pro-Ala or a salt thereof as an active ingredient. The nerve cell differentiation promoting agent has a high nerve cell differentiation promoting activity, and the peptide (Gly-Pro-Ala) which is an active ingredient is derived from a living body such as collagen, and therefore has high safety. The neuronal differentiation promoting agent can be used as a therapeutic agent for neurological diseases (for example, Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, dementia, depression) in the brain of humans and non-human animals. .
