WebJun 1, 2011 · The zebrafish epiphysis or pineal gland provides a powerful model for the study of cell fate choice, owing to its simplicity. Indeed, the epiphysial vesicle, which is located in the dorsal diencephalon, contains only two types of neurons: photoreceptors (PhRs) and projection neurons (PNs) (Masai et al., 1997).Previous studies have shown … WebThe pineal gland is a neuroendocrine structure in the brain, which produces and secretes the hormone melatonin at nighttime and is considered a key element in the circadian clock system. Early morphogenesis of the gland is controlled by a number of transcription factors, some of which remain active in adult life.
