tRNA in developing human placenta

Experientia, 1980
Amino acid acceptor activity of tRNA in the human placenta as measured throughout gestation was found to be the lowest in post-term placenta. Aminoacylation of tRNA proceeded with maximum activity in the stage of formation of the placenta.

Human Placenta—An Antibody Sponge?

American Journal of Reproductive Immunology and Microbiology, 1988
ABSTRACT: Maternal IgG antibodies in sera and placenta eluates were studied by a cellular enzyme‐linked immunosorbent assay (CELISA) method. Antibodies were not detectable in any of the serum samples obtained before or after delivery from nine normal primigravid women.

Lectin histochemistry of human placenta

Differentiation, 1984
The human placenta was studied histochemically using 23 fluorescein-isothiocyanate-labeled lectins. Distinct patterns of staining, as well as some differences between first-trimester and term placenta, were discerned. Eleven lectins (HPA, VVA, BPA, HAA, SBA, PNA, GSA-I, MPA, RCA-I, RCA-II, and UEA-I) did not react with the trophoblast. Two lectins (LCA

Ultrastructure of the normal human placenta

Electron Microscopy Reviews, 1991
In this review, the ultrastructure of the normal human chorionic villus is examined and illustrated. The outer covering of trophoblast, comprising the generative cytotrophoblast and the multinucleated syncytiotrophoblast which is derived from it, is described, including such features as the microvillous surface, vesicles and vacuoles, endoplasmic ...

Identification of somatostatin in the human placenta

Acta Endocrinologica, 1982
Abstract. High pressure liquid chromatography (HPLC), gel chromatography and radioimmunoassay (RIA) were applied to the identification of cyclic somatostatin in human placental tissue. Methanol extracts of the placenta were treated with acetic acid and chloroform, purified on an octadecylsilane column, fractionated on HPLC and gel filtration, and ...

Neuroendocrinology of the human placenta

1990
Abstract: The frontiers of placental endocrinology have been enlarged in the last decade. The hypothesis that the placenta could produce typical neuronal substances has been largely confirmed. Indeed, human placenta is a source of brain, pituitary, gonadal, and adrenocortical hormones.
