Fetal liver is the major embryonic hematopoietic organ and is extrinsically colonized by circulating hematopoietic stem cells (HSCs). Integrin beta-1 expression on HSCs is crucial for colonization, suggesting that interaction of Integrin beta-1 with extra-cellular matrix (ECM) factors promotes HSC adherence to fetal liver. However, little is known about how ECM production is regulated in fetal ...

Three hundred twenty fetuses were obtained from 33 pregnant gilts (Camborough-22, Pig Improvement Co.) to determine rates of nutrient deposition in fetal tissues and to estimate nutrient requirements for fetal growth. Pregnant gilts were fed an equal amount of a gestation diet (2.0 kg/d; as-fed basis), and were slaughtered at d 0, 45, 60, 75, 90, 102, or 110 of gestation (n = 3 to 6 per day). F...

Maternal thyroid hormone (TH) crosses the placenta and is postulated to regulate fetal brain development. However, TH-dependent stages of fetal brain development remain to be characterised. We have therefore compared the levels of several neuronal and glial cytoskeletal proteins in fetal brains from normal (N) and partially thyroidectomised (TX) rat dams by immunoblotting. Pregnancies were stud...

Hereditary thrombophilia is associated with an increased risk of fetal loss. Assuming that fetal loss is due to placental thrombosis, anticoagulant treatment might improve pregnancy outcome. In an observational family cohort study, we prospectively assessed the effects of anticoagulant drugs on fetal loss rates in women with hereditary deficiencies of antithrombin, protein C or protein S. The c...

OBJECTIVE To investigate the abundance of metabolic proteins in adult and fetal human livers. METHODS Adult liver homogenate proteins, fetal liver homogenate proteins, adult liver mitochondrial proteins and fetal liver mitochondrial proteins were obtained from fetal or adult liver tissues and examined using the antibody microarrays containing 19 liver monoclonal mitochondrial antibodies. The ...

Uniformly labeled [14C]lysine was infused at constant rate into the inferior vena cava of eight ovine fetuses with gestational ages ranging from 110 to 145 days. The infusion lasted 9 to 13 h and produced a steady-state specific activity of free lysine in the fetal plasma. In the steady state, approximately 9% of the infused radioactivity was excreted by the fetus as 14CO2, indicating fetal cat...

Insulin has long been assigned a key role in the regulation of growth and metabolism during fetal life. Our prior observations indicated that hepatic insulin signaling is attenuated in the late-gestation fetal rat. Therefore, we studied the perinatal ontogeny of hepatic insulin signaling extending from phosphatidylinositol 3-kinase (PI3K) to the ribosome. Initial studies demonstrated markedly d...

The protein Z-protein Z-dependent inhibitor complex is a factor Xa inhibitor. Protein Z deficiencies have recently been described in patients with ischemic stroke. As placenta infarction leads to poor pregnancy outcome, we studied protein Z plasma concentrations in nonthrombotic, nonthrombophilic consecutive patients with unexplained pregnancy wastage. A significant amount of protein Z deficien...

Vitamin D-binding protein is a multifunctional serum protein with multiple actions related to normal health. Vitamin D-binding protein transports vitamin D and influences the metabolism of this key hormone but it also has additional immunomodulatory and actin-clearing properties. We investigated whether vitamin D-binding protein expression is altered in fetal growth restriction-associated place...

Abstract
 Aim: The 97-kDa Valosin-containing protein has important functions in proteolysis. Although the expression of p97 / VCP been studied many types cells and tissues, localization at cellular level developing mouse pancreas liver not determined. Therefore, aim our study was investigate immuolocalization p97/VCP rat fetal postnatal pancreas. 
 Material Methods: from fetal, (1, 5,...
