Non-invasive prenatal genetic screening: an interview with Dr. Charles Strom, Senior Medical Director, Quest Diagnostics

A new category of non-invasive genetic screening tests is gaining a great deal of interest in the medical field – including from Quest Diagnostics -- for its potential to help screen women during pregnancy for genetic abnormalities known as trisomies, the most common of which is Down syndrome.

Study shows effects of maternal obesity on fetuses

Study shows effects of maternal obesity on fetuses

In a study to be presented on February 15 between 8 a.m. and 10 a.m. PST, at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in San Francisco, California, researchers from Tufts Medical Center will present findings showing the effects of maternal obesity on a fetus, specifically in the development of the brain.

Sequencing-based test effectively detects many fetal genetic defects

Sequencing-based test effectively detects many fetal genetic defects

Researchers have developed a new screening test that allows detection of fetal abnormalities in maternal blood by deep sequencing cell-free DNA extracted from plasma. [More]

Microarray analysis ‘best test for prenatal diagnosis’

Chromosomal microarray analysis is able to identify significantly more clinically relevant information for prenatal diagnosis than is karyotyping, and is equally able to highlight aneuploidies and unbalanced rearrangements, US study findings suggest. [More]
New prenatal genetic test results in more clinically relevant information

New prenatal genetic test results in more clinically relevant information

A large, multi-center clinical trial led by researchers from Columbia University Medical Center (CUMC) shows that a new genetic test resulted in significantly more clinically relevant information than the current standard method of prenatal testing. [More]
Vascular cell generation could be used to treat vascular disorders

Vascular cell generation could be used to treat vascular disorders

A study in mice has shown that large numbers of vascular endothelial cells can be generated from human amniotic fluid-derived cells. [More]
Reprogrammed vascular endothelial cells from ACs shows promise against vascular disorders

Reprogrammed vascular endothelial cells from ACs shows promise against vascular disorders

A new approach for generating large numbers of circulatory system cells, known as vascular endothelial cells (VECs), from human amniotic-fluid-derived cells (ACs) is reported in a study published by Cell Press October 18th in the journal Cell. The strategy, which shows promise in mice, opens the door to establishing a vast inventory of VECs for promoting organ regeneration and treating diverse vascular disorders. [More]
Reprogrammed endothelial cells for treatment of vascular disorders

Reprogrammed endothelial cells for treatment of vascular disorders

A research team at Weill Cornell Medical College has discovered a way to utilize diagnostic prenatal amniocentesis cells, reprogramming them into abundant and stable endothelial cells capable of regenerating damaged blood vessels and repairing injured organs. [More]

Fetal fraction of cfDNA does not vary significantly among pregnant women regardless of trisomy risk

A study published in The Journal of Maternal-Fetal and Neonatal Medicine demonstrates that the fraction of fetal cell-free DNA (cfDNA) in maternal blood is unaffected by the mother's presumed risk for trisomy, offering support for the use of non-invasive prenatal testing (NIPT) for detecting genetic conditions such as Down syndrome in a broad patient population.

Researchers use maternal blood sample to sequence genome of an unborn baby

Researchers use maternal blood sample to sequence genome of an unborn baby

Researchers at the Stanford University School of Medicine have for the first time sequenced the genome of an unborn baby using only a blood sample from the mother. [More]
Scientists reprogram amniotic fluid cells without introduction of extra genes

Scientists reprogram amniotic fluid cells without introduction of extra genes

Stem cells found in amniotic fluid can be transformed into a more versatile state similar to embryonic stem cells, according to a study published today in the journal Molecular Therapy. Scientists from Imperial College London and the UCL Institute of Child Health succeeded in reprogramming amniotic fluid cells without having to introduce extra genes. [More]

Novel assay accurately detects trisomy 21 or 18 from maternal blood samples

Current screening strategies for Down syndrome, caused by fetal trisomy 21 (T21), and Edwards syndrome, caused by fetal trisomy 18 (T18), have false positive rates of 2 to 3%, and false negative rates of 5% or higher. Positive screening results must be confirmed by amniocentesis or chorionic villus sampling, which carry a fetal loss rate of approximately 1 in 300 procedures. Now an international, multicenter cohort study finds that a genetic test to screen for trisomy 21 or 18 from a maternal blood sample is almost 100% accurate. [More]

LifeCodexx completes PraenaTest clinical study on trisomy 21

LifeCodexx today announced the successful completion of the clinical validation study of its noninvasive test method for the detection of fetal trisomy 21 from maternal blood using Next Generation sequencing. [More]

DANSR/FORTE assay more effective in diagnosing Edwards and Down syndrome

Using a noninvasive test on maternal blood that deploys a novel biochemical assay and a new algorithm for analysis, scientists can detect, with a high degree of accuracy, the risk that a fetus has the chromosomal abnormalities that cause Down syndrome and a genetic disorder known as Edwards syndrome. [More]

Obama campaign pushes back against Santorum attack on prenatal testing

Campaigning in Ohio on Saturday, Rick Santorum displayed his culture-warrior side in full force ... He lambasted the president's health care law requiring insurance policies to include free prenatal testing, "because free prenatal testing ends up in more abortions and therefore less care that has to be done because we cull the ranks of the disabled in our society". [More]

Researchers derive vessel-forming stem cells from amniotic fluid

Researchers at Rice University and Texas Children's Hospital have turned stem cells from amniotic fluid into cells that form blood vessels. Their success offers hope that such stem cells may be used to grow tissue patches to repair infant hearts. [More]

Non-invasive test for early detection of fetal gender

A new research study published in the January 2012 edition of The FASEB Journal describes findings that could lead to a non-invasive test that would let expecting mothers know the sex of their baby as early as the first trimester. [More]

A more accurate blood test to detect fetal Downs syndrome launched

Pregnant mothers in the U.S. who wish to know whether they're carrying a fetus with Down syndrome now have access to a commercial genetic blood test that has a 99 per cent accuracy rate. [More]
