متن کاملCell-free fetal nucleic acids in amniotic fluid.
BACKGROUND Research into cell-free fetal (cff) nucleic acids has primarily focused on maternal plasma; however, cff DNA and RNA are also detectable in other body fluids such as amniotic fluid (AF). In AF, cff DNA is present in much greater concentrations than in maternal plasma and represents a pure fetal sample uncontaminated by maternal- and trophoblast-derived nucleic acids. The aim of this ...

متن کاملCell-free fetal DNA in amniotic fluid: unique fragmentation signatures in euploid and aneuploid fetuses.
BACKGROUND Circulating cell-free fetal deoxyribonucleic acids (cffDNA) are novel biomarkers with many clinical applications. Amniotic fluid (AF) is a rich source of cffDNA. We investigated the biophysical characteristics of cffDNA in AF, hypothesizing that they would differ from cffDNA in maternal plasma. METHODS We obtained 10 mL of fresh AF supernatant from women carrying euploid fetuses (n...
متن کاملCell-free fetal DNA in amniotic fluid supernatant for prenatal diagnosis.
In widespread conviction, amniotic fluid is utilized for prenatal diagnosis. Amniotic fluid supernatant is usually discarded, notwithstanding being a good source of fetal DNA. The aim of the present study was to assess cell-free fetal DNA extracted from amniotic fluid supernatant for application in prenatal diagnosis such as gender determination and early diagnosis of β-thalassemia. Samples of ...
