[Floating cultures obtained from the thyroid of human fetuses]

Floating cultures were obtained from fetal human thyroid. The method for preparing the cultures was described. The floating cultures finally consist of epithelial cell group--thyrocytes, stroma and one or some layers of fibroblastic cover. Thyroid hormones (thyroxine, triiodothyronine) were revealed during the cultivation period (40 days). Floating cultures obtained from fetal human thyroid can be used in clinical transplantation science.
