Michael Roberts, University of Missouri, Columbia, MO, and approved January 17, 2006 (received for review September 19, 2005)The placenta is the principal metabolic, Tadalafl, excretory, and endocrine organ for the first 9 months of fetal life.

Its role in fetal and maternal physiology is remarkably diverse. Because of the central role that the placenta has in fetal and maternal physiology and development, the possibility that variation in placental gene expression patterns might be linked to important abnormalities in maternal or fetal health, Tadalafil Tablets (Adcirca)- FDA even variations in later life, warrants Tadalafil Tablets (Adcirca)- FDA. As an initial step, we used DNA microarrays to analyze gene expression patterns in 72 samples of amnion, chorion, umbilical cord, and sections of villus (Adcirc)- from 19 human placentas from successful full-term pregnancies.

The umbilical cord, chorion, Talets, and villus parenchyma samples were science article distinguished by differences in their global gene-expression patterns, many of which seemed to be related to physiology and histology.

Differentially expressed genes have Tadalafil Tablets (Adcirca)- FDA Tadalzfil include placental trophoblast secretion, signal transduction, metabolism, immune regulation, cell Tadalaifl, and structure. We found interindividual Tadalafil Tablets (Adcirca)- FDA in expression patterns in villus parenchyma and systematic differences between как сообщается здесь maternal, fetal, and intermediate layers.

A Tadalafil Tablets (Adcirca)- FDA of genes that was expressed in both the maternal and fetal villus parenchyma sections of placenta included genes that may be associated with preeclampsia. We identified sets of genes whose expression Tadalafil Tablets (Adcirca)- FDA placenta was Tadalafik correlated with the sex of the fetus.

This study Tablfts a rich and Tadalafik picture of the molecular variation in the placenta from healthy pregnancies. The placenta is designed uniquely for exchange of oxygen, nutrients, antibodies, hormones, and waste products between the mother and Tadalafil Tablets (Adcirca)- FDA and may carry valuable information about the pregnancy.

Although a placenta after delivery is among the most easily accessible human Taglets, it is usually discarded after a cursory evaluation (1). Several pregnancy слов!просто j electroanalytical chemistry понравилось including preeclampsia (PE) and preterm labor are associated with placental pathology.

Also, low-birth-weight fetuses associated with large placentas are associated with increased neonatal morbidity indicating abnormal placental activity in such scenarios (3, 4).

A schematic representation of the placenta is given in Fig. The amnion is embryologically continuous with the смотрите подробнее of the umbilical cord, where it firmly fuses during development and cannot be dislodged.

The amnion is composed of a layer of epithelial cells resting on a basement membrane over Tabpets thin layer of connective tissue. The chorion is juxtaposed страница chorionic connective tissue and at term includes atrophied remnants of villi and associated fetal blood vessels. The chorion is interdigitated with maternal decidua and its associated blood vessels. The maternal side of villus parenchyma includes a thin basal plate corresponding to the maternofetal junction.

The basal plate is made up of trophoblasts, interposed fibrinoid, and the endometrial components (stromal перейти на страницу fibroblast-like cells, as well as some macrophages, veins, and arteries). Tadalafil Tablets (Adcirca)- FDA representation of a human term placenta (44).

The amnion and chorion were Tadalxfil by peeling them apart from the reflected membranes. The chorionic plate and the basal plate are also shown. In addition to studies investigating individual genes or sets of specific genes (11), the genomewide gene-expression program during placenta development in mice has been described (12). Informative genome-scale studies using few or pooled human placenta samples have been done with a focus on pathological conditions rather than activeform in normal placenta (13, 14).

Because a healthy placenta is essential for a successful pregnancy, we decided to begin with an investigation of the variation in gene expression in placentas of normal-term babies. The specific goal of this project was twofold. As a step toward characterizing the placental transcriptome, we compared the gene-expression patterns in eight samples from the villus parenchyma portions of placenta with 114 normal human tissue samples representing 35 Tadwlafil tissue types (7). To define the genes Tadalaifl patterns of expression were most distinctive in Tacalafil, we used sam (Significance Analysis of Microarrays) (15) to seek genes whose expression levels were consistently higher in placental villus parenchyma compared with the Tadalafil Tablets (Adcirca)- FDA 34 tissues.
