Abstract

The aim of this study was to investigate the expression of Nodal (NODAL Homolog (mouse), Nanog (Nanog Homeobox), DAZL (Deleted in Azoospermia Like) and SMAD (SMAD Family member) genes and their potential role in the regulation of self-renewal in human amniotic fluid-derived stem cells. In this experimental study human amniotic fluid-derived stem cells were analyzed for messenger RNA expression of Nodal. Immunocytochemistry also was performed to determine Nanog and DAZL. SMAD genes expression analysis was performed using cDNA Microarray analysis. Nodal mRNA was positively expressed in all samples of amniotic fluid derived stem cells. Amniotic fluid-derived stem cells showed strong immunoreactivity for molecular markers of undifferentiated human embryonic stem cells including Nanog and DAZL. Among the 8 SMAD genes expressions analyzed SMAD1, SMAD2, SMAD3, SMAD4 and SMAD7 showed positive expression. In conclusion amniotic fluid-derived stem cells seem to express Nodal, Nanog and DAZL and it speculated that the regulation of self-renewal in AFSc could be similar as in human embryonic stem cells.

Nodal、Nanog、DAZL和SMAD基因在人羊水干细胞中的表达。

本研究的目的是研究Nodal(小鼠)、Nanog (Nanog Homeobox)、DAZL (Deleted in Azoospermia Like)和SMAD (SMAD家族成员)基因的表达及其在人羊水来源干细胞自我更新调控中的潜在作用。本实验研究分析了人羊水干细胞中Nodal信使RNA的表达。免疫细胞化学检测Nanog和DAZL。采用cDNA Microarray分析SMAD基因表达。在所有羊水干细胞样本中，淋巴结mRNA均呈阳性表达。羊水干细胞对Nanog和DAZL等未分化人胚胎干细胞分子标记具有较强的免疫反应性。在分析的8个SMAD基因表达中，SMAD1、SMAD2、SMAD3、SMAD4和SMAD7表达阳性。综上所述，羊水干细胞似乎表达Nodal、Nanog和DAZL，推测AFSc中自我更新的调控可能与人类胚胎干细胞相似。
