title: [Prenatal diagnosis of chromosomal anomalies by chorionic villi sampling: culture technic and preliminary results].
abstract: Chorionic villi biopsies made during the first trimester of pregnancy allow an early prenatal diagnosis of many fetal abnormalities. The authors described a simple and rapid method of mesenchymal cells culture which have the advantage of improving the quality and number of the mitoses examined.
