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

WebJan 8, 2024 · The basic fibroblast growth factor (bFGF), a potent angiogenesis-promoting growth factor, can significantly facilitate the survival, proliferation, and neuronal differentiation of neural stem cells (NSCs); prevent cell apoptosis; and restore the function of the central nerve system (CNS) after injury [40–48]. WebDec 1, 2006 · Fibroblast growth factor (Fgf) and retinoic acid (RA) signals control the formation and anteroposterior patterning of posterior hindbrain. They are also involved in development processes in other regions of the embryo. Therefore,responsiveness to Fgf and RA signals must be controlled in a context-dependent manner.
