Evidence for the Placental Transfer of 3H-Acetyl-Melatonin

Abstract

DEVELOPMENTAL studies on the enzymes which form melatonin, the putative pineal hormone, indicate that it probably is not formed in rats before the tenth day of life1–3. Melatonin could nevertheless arise in animals younger than 10 days of age by transfer from the mother, and we now describe how we have investigated this possibility by determining whether 3H-acetyl-melatonin injected into a pregnant rat could be detected in its foetuses.
