AI Article Synopsis
- Amniotic and allantoic fluids, along with afferent lymph, promote DNA synthesis in bovine fetal myoblasts at low concentrations (5%), but higher doses inhibit this effect.
- The negative impact on DNA synthesis is more pronounced when the fluids are lyophilized before use.
- Afferent lymph enhances protein synthesis in bovine fetal myoblasts in a dose-dependent manner.
Article Abstract
Amniotic and allantoic fluids, as well as afferent lymph (tissue fluid), stimulated DNA synthesis in bovine fetal myoblasts (BFM) at low concentrations (5%). Higher doses abolished the mitostimulatory effect of these fluids and led toward inhibition of [3H]mTdR incorporation into DNA. These effects were much more evident (particularly in the case of amniotic fluid) when fluids were lyophylized prior to the experiment. BFM protein synthesis was accelerated by lymph in a dose dependent manner.

Effect of gestational age and fetal sex on metabolism of creatine by uteri, placentae, and fetuses of pigs†.

The creatine (Cr) biosynthesis pathway buffers ATP in metabolically active tissues. We investigated whether sex of fetus and day of gestation influence Cr in endometrial and conceptus tissues from gilts on Days 60 and Day 90 (n = 6 gilts/day) of gestation. Uterine and conceptus tissues associated with one male and one female fetus from each gilt were analyzed for creatine, mRNAs, and proteins for Cr biosynthesis.

The present study aimed to evaluate the acute phase proteins (serum amyloid A, alpha-1 acid glycoprotein, and C-reactive protein) profile in canine and feline fetal fluids during the second half of gestation. Seventeen pregnant domestic short-hair queens and 19 pregnant mixed-breed bitches were enrolled. Animals were divided into three groups according to their gestational age (30-39, 40-49, and 50-60 days).

One-carbon metabolites (OCM) are metabolites and cofactors which include folate, vitamin B12, methionine, and choline that support methylation reactions. The objectives of this study were to investigate the effects of moderate changes in maternal body weight gain in combination with OCM supplementation during the first 63 d of gestation in beef cattle on (1) B12 and folate concentrations in maternal serum (2) folate cycle intermediates in maternal and fetal liver, allantoic fluid (ALF), and amniotic fluid (AMF) and (3) metabolites involved in one-carbon metabolism and related metabolic pathways in maternal and fetal liver. Heifers were either intake restricted (RES) and fed to lose 0.

Embryonic mortality is a significant problem in the commercial duck industry worldwide. Therefore, identification of new biomarkers for duck embryo development is necessary. In the chicken (order Galliformes), we previously showed that chemerin is a hormone locally produced by the reproductive tract in hens, particularly in the magnum area, leading to its accumulation in the egg white and within the embryo annexes during embryonic development.

The placenta links feto-maternal circulation for exchanges of nutrients, gases, and metabolic wastes between the fetus and mother, being essential for pregnancy process and maintenance. The allantois and mesodermal components of amnion, chorion, and yolk sac are derived from extraembryonic mesoderm (Ex-Mes), however, the mechanisms contributing to distinct components of the placenta and regulation the interactions between allantois and epithelium during chorioallantoic fusion and labyrinth formation remains unclear. Isl1 is expressed in progenitors of the Ex-Mes and allantois the Isl1 mut mouse line is analyzed to investigate contribution of Isl1 Ex-Mes / allantoic progenitors to cells of the allantois and placenta.
