Retinoids, retinoic acid and its bioisomers regulate many biological functions such as cell differentiation, proliferation and embryonic development in vertebrates, through binding to and activating their specific nuclear receptors.
Five representative synthetic retinoids are available for the researchers investigating in signal transduction system through retinoids receptors.
