Danish Biotech Company, FCMB, has discovered a breakthrough in risk-free prenatal diagnostic. (Press Release) Vejle, Denmark (MMD Newswire) December 29, 2008 -- Danish Biotech Company, FCMB, has discovered a breakthrough in risk-free prenatal diagnostic. For the first time specific gene expression information from fetal cells isolated from maternal blood samples is available. FCMB has created a cDNA library originating from fetal cells revealing expression patterns different from maternal blood cells. It has been known for the past four decades that throughout pregnancy, fetal cells pass the placenta and circulate in the maternal bloodstream. Collecting fetal cells from a maternal blood sample for subsequent molecular diagnostics is difficult because there are very few of them in a blood sample. In order to distinguish them from maternal blood cells one needs to have a very specific marker. To create such markers it’s necessary to know what is different in fetal cells in relation to maternal blood cells. The knowledge of this difference, the specific protein occurring only in fetal cells, is what allows selection of those cells. A gene expression profile, obtained by a combination of cDNA library and micro array experiments, reveals such differences and is the base for developing this fetal cell recognition system. FCMB has created this breakthrough cDNA library using proprietary preparation methods. |
