Neuronal Differentiation of Human Neuroblastoma Cells by Retinoid

Induction of Human Embryonic Stem Cells into neuronal differentiation by increasing cyclic Adenosine Mono Phosphate

Introduction: To evaluate the cAMP -mediated IBMX (3-IsoButyle -1-Methyl Xanthin) and db-cAMP (dibutyryl cAMP) effects on differentiation of human Embryonic Stem Cells (hESCs) into nerve cells were the objectives of this study. Methods: We have used Royan H1 hESC- derived embryoid bodies with four treatment groups: six days treatment with IBMX (5×10 -4M) and db-cAMP (10 -9M) (referred to as...

Neuronal cell differentiation of human neuroblastoma cells by retinoic acid plus herbimycin A.

We investigated the effect of retinoic acid (RA) and herbimycin A (herb-A) on cell growth, cell differentiation, and colony formation of human neuroblastoma cell lines. The neuroblastoma line SK-N-SH expressed both neuroblast and nonneuronal phenotypes, whereas its subclone SH-SY5Y and the Kelly cell line were predominantly neuroblastic. Both herb-A and RA, given alone, moderately reduced cell ...

induction of human embryonic stem cells into neuronal differentiation by increasing cyclic adenosine mono phosphate

introduction: to evaluate the camp -mediated ibmx (3-isobutyle -1-methyl xanthin) and db-camp (dibutyryl camp) effects on differentiation of human embryonic stem cells (hescs) into nerve cells were the objectives of this study. methods: we have used royan h1 hesc- derived embryoid bodies with four treatment groups: six days treatment with ibmx (5×10 -4m) and db-camp (10 -9m) (referred to as cam...

Expression of retinoid receptors during the retinoic acid-induced neuronal differentiation of human embryonal carcinoma cells.

Retinoic acid (RA), a derivative of vitamin A, is essential for normal patterning and neurogenesis during development. Until recently, studies have been focused on the physiological roles of RA receptors (RARs), one of the two types of nuclear receptors, whereas the functions of the other nuclear receptors, retinoid X receptors (RXRs), have not been explored. Accumulating evidence now suggests ...
