متن کاملCardiomyocyte Marker Expression in Mouse Embryonic Fibroblasts by Cell-Free Cardiomyocyte Extract and Epigenetic Manipulation
Background: The regenerative capacity of the mammalian heart is quite limited. Recent reports have focused on reprogramming mesenchymal stem cells into cardiomyocytes. We investigated whether fibroblasts could transdifferentiate into myocardium.Methods: Mouse embryonic fibroblasts were treated with Trichostatin A (TSA) and 5-Aza-2-Deoxycytidine (5-aza-dC). The treated cells were permeabilized w...
متن کاملCell - free DNA: بیومارکر نوین تشخیص آزمایشگاهی
به انواع مختلف اسیدهای نوکلئیک آزاد در پلاسما شامل قطعات DNA ژنومی،DNA میتوکندریایی، DNA و mRNA های ویروسی و همچنین انواع miRNA اصطلاحا Cell–free nucleic acid گفته می شود. بخش مهمی از این اسیدهای نوکلئیک آزاد در پلاسما را Cell–free DNA (cfDNA) تشکیل می دهد. cfDNA به صورت قطعاتی با وزن مولکولی حدود KB 21-0.18 در سرم یا پلاسمای افراد سالم و افراد مبتلا به بسیاری از بیماری ها قابل تشخیص هستند. ...
متن کاملImpact of Cell-Free Fetal DNA Screening on Patients’ Choice of Invasive Procedures after a Positive California Prenatal Screen Result
Until recently, maternal serum analyte levels paired with sonographic fetal nuchal translucency measurement was the most accurate prenatal screen available for Trisomies 18 and 21, (91% and 94% detection and false positive rates of 0.31% and 4.5% respectively). Women with positive California Prenatal Screening Program (CPSP) results have the option of diagnostic testing to determine definitivel...
متن کاملFalse Negative Cell-Free DNA Screening Result in a Newborn with Trisomy 13
Background. Noninvasive prenatal screening (NIPS) is revolutionizing prenatal screening as a result of its increased sensitivity, specificity. NIPS analyzes cell-free fetal DNA (cffDNA) circulating in maternal plasma to detect fetal chromosome abnormalities. However, cffDNA originates from apoptotic placental trophoblast; therefore cffDNA is not always representative of the fetus. Although the ...
