Identification of trophoblast in chorionic villi biopsy samples

Human Genetics, 1986
We have investigated a test for rapid discrimination between foetal and maternal origin of chorionic villi biopsy samples. A monoclonal antibody named H315 reacting against a specific antigen present on the surface of foetal trophoblastic cells, plus a double-colour staining technique (FITC + PI), have been used for the identification of foetal cells ...

Chorion Villi Sampling (CVS)

1994
Die Technik der Chorionzottenbiopsie (CVS) wurde in der VR China und in der Sowjetunion entwickelt (218). Das Konzept hierzu stammt schon aus dem Jahre 1968 (307, 638). Unter Verwendung von Aspirationskathetern oder — kanulen sowie Biopsiezangen last sich im I. Trimester zwischen der 7. und 12.

[Experience with chorionic villi sampling].

Orvosi hetilap, 1991
The authors discuss their experiences from 412 chorion villus samplings, (CVS), which they have done under four and a half years since 1985. They used eight types of instruments in performing their examinations and each instrument proved to be satisfactory in the gaining of chorion villus samples, suitable for further tests.

Investigations of chorionic villi after chorionic villus sampling (CVS)

Human Genetics, 1989
This report documents the first 262 cases of chorionic villus sampling (CVS) performed in parallel with cytogenetic and morphological investigations. Histomorphological examination of these CVS specimens gave suitable results in about 96% (251 cases). Of the latter, 201 samples (80.1%) exhibited villi and 176 (70.1%), maternal tissue.

Monitoring of Pregnancies at Risk for Fanconi’s Anemia by Chorionic Villi Sampling

Acta Haematologica, 2009
Two pregnancies at risk for Fanconi’s anemia have been monitored by a cytogenetic method in the first trimester of gestation. The rate of chromosome breakage was evaluated in spontaneous mitoses from a direct preparation of trophoblasts in one case and from mitoses obtained from standard cultures and from mitoses treated with diepoxybutane in both ...

Chorionic villi sampling: Laboratory experience with 4,000 consecutive cases

American Journal of Medical Genetics, 1994
AbstractExperience with 4,000 consecutive CVS cases shows that 1) the combination of both the direct and culture methods greatly reduces false diagnoses and maternal cell contamination; 2) the time interval between the sampling procedure and processing of villus specimens influences the quality of direct preparations; 3) maternal cell contamination ...

[Sampling, culturing and karyotyping of chorionic villi].

Journal de gynecologie, obstetrique et biologie de la reproduction, 1984
The authors report on 69 samples of chorionic villi taken from patients who were undergoing therapeutic termination of pregnancy. These samples were taken using small forceps which were guided by ultrasound. The reliability and the chances of culturing these villi in order to work out the caryotype of the fetus and to study the enzymes is discussed.

[Chorionic villi sampling. Amniocentesis. Cordocentesis].

Revue francaise de gynecologie et d'obstetrique, 1990
For early antenatal diagnosis, chorionic villus sampling (CVS) represents a valid alternative to early amniocentesis. It gives rapid results with minimal increase in risks (miscarriage about 1.5 p. cent). The indications of CVS are therefore likely to broaden. For late antenatal diagnosis, linked to an echographic or clinical anomaly, sampling of fetal
