Midkine (MK), a retinoic acid responsive gene product, is a novel neurotrophic factor with a molecular weight of 14,000. MK at the optimal concentration of 10 ng/ml promoted the survival of mouse mesencephalic neurons in culture as demonstrated by the increased number of microtubule-associated protein-2 (MAP2) immunostaining-positive and tyrosine hydroxylase immunostaining-positive neurons and an elevated uptake of radiolabeled dopamine. These results suggest that MK has ubiquitous neurotrophic activity towards mesencephalic neurons which contain a large number of dopaminergic neurons.

D008636	Mesencephalon	The middle of the three primitive cerebral vesicles of the embryonic brain. Without further subdivision, midbrain develops into a short, constricted portion connecting the PONS and the DIENCEPHALON. Midbrain contains two major parts, the dorsal TECTUM MESENCEPHALI and the ventral TEGMENTUM MESENCEPHALI, housing components of auditory, visual, and other sensorimoter systems.

D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
