Immunocytochemical identification of cytotrophoblast from other mononuclear cell populations isolated from first-trimester human chorionic villi.
Trophoblast biologists are often uncertain as to what cell types they are investigating because the mononuclear cell populations prepared from trypsinization of human first-trimester chorionic villi are morphologically very similar. In the present study, immunocytochemical and phagocytic markers have been used to distinguish cytotrophoblast populations from cell types derived from the mesenchym...
متن کاملMethod of sampling chorionic villi in first trimester of pregnancy under guidance of real time ultrasound.
Samples of chorionic villi were obtained in the first trimester by aspiration using a cannula passed transcervically under the guidance of real time ultrasound. In initial studies in 47 anaesthetised patients immediately before therapeutic abortion a method was developed giving a success rate of 89%. In 10 patients successful sampling was performed as an outpatient procedure without anaesthesia...
متن کاملLocalization of major histocompatibility complex class I and II mRNA in human first-trimester chorionic villi by in situ hybridization
Maternal immune recognition of pregnancy occurs despite the nonexpression of classical major histocompatibility complex (MHC) antigenic determinants by chorionic villous trophoblast, which comprise the major surface area where maternal blood contacts fetal-derived cells. cDNA-mRNA in situ hybridization was used to probe expression of transcripts corresponding to nonpolymorphic MHC determinants ...
متن کاملHuman chorionic gonadotropin-beta gene expression in first trimester placenta.
The hCGbeta gene family contains six genes linked in tandem on chromosome 19 and labeled beta genes 7, 8, 5, 1, 2, and 3. Previous studies on a small number of placentas have indicated that beta gene 5 was the most highly expressed gene during the first trimester of pregnancy, followed by genes 3 and 8. Beta genes 7, 1, and 2 were expressed at very low levels. The purpose of this study was to d...
متن کاملOverview of Chromosome Abnormalities in First Trimester Miscarriages: A Series of 1,011 Consecutive Chorionic Villi Sample Karyotypes.
In order to contribute to the knowledge of type and frequency of chromosome abnormalities in early pregnancy losses, we analyzed the cytogenetic results from a large series of first trimester miscarriages, using a diagnostic approach with a high success rate and no maternal contamination. A total of 1,119 consecutive chorionic villi samples were obtained before evacuation, and karyotypes were p...
