[Cultivation of chorionic cells in studying the fetal karyotype in the 1st trimester of pregnancy].
Primary culture of chorion cells obtained during the first trimester of pregnancy (7-9 weeks) through artificial abortion or by transcervical biopsy of the chorion tissue is an object for cytogenetic examination of fetus cells. The application of this cell culture for prenatal diagnosis of human hereditary diseases has a considerable advantage in time as compared with a routine method of using amniotic fluid cell culture during the second trimester of pregnancy.
