The requirement for vitamin A in reproduction was first recognized in the early 1900's, and its
importance in the eyes of developing embryos was realized shortly after. A greater …

The key role of vitamin A in embryonal development is reviewed. Special emphasis is given
to the physiological action of retinoids, as evident from the retinoid ligand knockout models …

Neuraxial patterning is a continuous process that extends over a protracted period of
development. During gastrulation a crude anteroposterior pattern, detectable by molecular …

The molecular mechanisms that control regional specification, morphogenesis and
differentiation of the embryonic forebrain are not known, although recently seueral …

Retinoic acid (RA) is a morphogen derived from retinol (vitamin A) that plays important roles
in cell growth, differentiation, and organogenesis. The production of RA from retinol requires …
