[Development of the human parathyroid during the fetal period]. 1981

P Gouget, and G Godlewski, and P Baudin

Study of te human foetal parathyroid in 10 specimens from 27 to 360 mms 1.06 to 14, 18 inches) in length. Macroscopically the gland can be located by the recognition of its arterial pedicle and in the fetus from 4 to 6 months old by the presence of pseudocysts of Kursteiner. The histologic investigation in optic microscopy shows the increasing density of cells with a dark nucleus placed beside the other cells without interposition of fat cells. The oxyphil cells and the clear cytoplasm cells are missing. Kursteiner's cysts are situated at the periphery of the gland. The organotypic cultures can be maintained during 5 to 7 days. The viability of the cells is checked with microscopy and with dosage of parathormon in the medium by radio-immuno-assay. The favorable results incite us to follow up the cultures in view of further grafts.

D005865 Gestational Age The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.
