domain. Retinoolhape indutseerib mitmeid kasvufaktoreid ja ka protoonkogeene. ... Vitamiin A :(retinool): organismile tasakaalu ja kaitset pakkuv antioksüdant, tagab silmade, limaskesta ja maksa tervise, vajalik luukoe, hammaste ja kõhrede arenguks, oluline spermatosoidide ja platsenta arenguks ja rakkude ehituseks kasvavale organismile. Retinoic acid is a derivate of vitamine A and a member of the steroid supefamily. Retinoic acid activates a unique class of transcription factors - retinoid receptors- that modulate the expression of a number of target genes. Peptide hormone provide another class of inuctive signals, including those that belong to the fibroblast growth factor (FGF) and transforming growth factor(TGF) families. Ano their petide hormone essential for neural induction is sonic hedgehog(shh). These
