  • Patent number: 10808239
    Abstract: Methods of isolating DNA of a fetus of an ongoing pregnancy are provided according to the present invention which include obtaining a maternal endocervical sample containing maternal cells and fetal extravillous trophoblast cells from a pregnant subject; isolating fetal extravillous trophoblast cells from the maternal endocervical sample, producing isolated fetal extravillous trophoblast cells contaminated with maternal DNA; lysing the isolated fetal extravillous trophoblast cells; isolating fetal nuclei from the lysed fetal extravillous trophoblast cells, producing isolated fetal nuclei, thereby removing at least a portion of the contaminating maternal DNA; and purifying genomic DNA from the isolated fetal nuclei, producing purified fetal genomic DNA. The purified fetal genomic DNA can be assayed to determine a characteristic of a genomic DNA sequence of the purified fetal genomic DNA, thereby determining a characteristic of DNA of a fetus of an ongoing pregnancy.
    Type: Grant

  • Patent number: 10330680
    Abstract: Methods of isolating and assaying fetal extravillous trophoblast cells, including assays of RNA of the fetal extravillous trophoblast cells according to aspects of the disclosure include obtaining a maternal endocervical sample containing fetal extravillous trophoblast cells from a pregnant subject; fixing the maternal endocervical sample in an aldehyde fixative, removing fetal extravillous trophoblast cells from the maternal endocervical sample thereby producing isolated extravillous trophoblast cells, isolating and assaying RNA from the fetal extravillous trophoblast cells.
    Type: Grant
