Maternal-fetal glucose exchange: necessity of a three-pool model

American Journal of Physiology-Endocrinology and Metabolism, 1984
Tracer glucose was infused simultaneously into mother ( [6-3H]glucose) and fetus ( [U-14C]glucose) in pregnant sheep in the last month of gestation to study the exchange of glucose molecules between maternal and fetal blood. Net rates of entry and exit of tracer glucose via the uterine and umbilical circulations were measured by application of the ...

113 INTERACTIONS BETWEEN THE VISCERAL YOLK SAC PLACENTA AND THE UTERINE WALL IN NECROMYS LASIURUS (RODENTIA, CRICETIDAE)—AN EXPERIMENTAL MODEL TO UNDERSTANDING THE MATERNAL–FETAL EXCHANGE

Reproduction, Fertility and Development, 2011
The establishment of pregnancy results from the interaction between the trophoblast and maternal tissues. Evolutionarily, the yolk sac (YS) is the only fetal membrane present in all vertebrate taxa. In mammals, it results in the development of the YS placenta, which is responsible for maternal–fetal exchange in the beginning of gestation. Its functions

Effects of maternal-fetal blood exchange transfusion in fetal lambs

American Journal of Obstetrics and Gynecology, 1971
Abstract An attempt to evaluate experimentally the effects of intrauterine fetal exchange transfusion on placental function is reported. In a series of acute experiments carried out on pregnant sheep and their fetal lambs, maternal-fetal cross transfusion, sufficient significantly to increase the content of maternal blood in the fetus, was ...

Comprehension of maternal-fetal exchange

Endocrine, 2002
1 During the twentieth century, major scientific studies focused on a discovery the etiology and treatment of adult pathologies and, to a lesser extent, neonatal pathologies, in order to provide better health for our society. Newborns represent our future, so it is important to ameliorate fetal and newborn health.

Maternal-Fetal Exchange of 59 Fe: Radiation Dosimetry and Biokinetics in Human and Sheep Studies

Radiation Research, 1973
The estimation of the absorbed radiation dose to the human fetus from59 Fe administered to the mother requires information on the biokinetics of the59 Fe within the mother and fetus. For the first part of pregnancy, up to about 24 wk gestation, information from studies done on women receiving therapeutic abortions is available.

Calcitropic gene expression suggests a role for the intraplacental yolk sac in maternal-fetal calcium exchange

American Journal of Physiology-Endocrinology and Metabolism, 2002
The expression of calcitropic genes and proteins was localized within murine placenta during late gestation (the time frame of active calcium transfer) with an analysis of several gene-deletion mouse models by immunohistochemistry and in situ hybridization. Parathyroid hormone-related protein (PTHrP), the PTH/PTHrP receptor, calcium receptor, calbindin-

GATA-regulated transcriptional program dictate cell fate equilibrium to establish the maternal-fetal exchange interface and fetal development

2023
Abstract The placenta establishes a maternal–fetal exchange interface to transport nutrients and gases between the mother and the fetus. Establishment of this exchange interface relies on the development of multinucleated syncytiotrophoblasts (SynT) from trophoblast progenitors and defect in SynT development often leads to pregnancy ...
