WebRetinoic Acid-FGF Antagonism during Motor Neuron Differentiation of Human ES Cells Public Abstract: Retinoic acid is a metabolic derivative of vitamin A that has recently been shown to stimulate differentiation of human embryonic stem cells into motor neurons. However, almost nothing is known about how retinoic acid may perform this function. Webbetween, retinoic acid (RA), Fgf and Wnt signals in the promotion of posterior fates in the ectoderm. We analyze expression and function of cyp26/P450RAI, a gene that encodes retinoic acid 4-hydroxylase, as a tool for investigating these events. Cyp26is first expressed in the presumptive anterior neural ectoderm and the blastoderm

WebThe nested domains of Hox gene expression, which provide a combinatorial code for axial patterning, arise in part through a differential response to retinoic acid (RA) diffusing from anabolic centers established within the embryo during development. Hence, Hox genes are important direct effectors of retinoid signaling in embryogenesis. WebAfter a 6-day treatment, FGF and retinoic acid induced a significant increase in the number of follicle-stimulating hormone (FSH) receptors per cell, and in FSH-induced cyclic adenosine 3',5'-monophosphate (cAMP) production.
