Infants may benefit if resuscitation could be provided with an intact umbilical cord. Infants identified at risk for resuscitation were randomized to 1- or 5-minute cord clamping. The 5-minute group had greater cerebral oxygenation and blood pressure. Studies are needed to determine whether this translates into improved outcomes. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02827409.

Since the outbreak of methylmercury (MeHg) poisoning in Japan and Iraq, mercury (Hg) is classified as well-established teratogen. The Portuguese region of Aveiro faced some decades ago an environmental Hg contamination due to activities from a chlor-alkali plant. Until now, no apparent evaluation was conducted regarding prenatal exposure to Hg in this area. The main objectives of this study were to: i) assess maternal and fetal exposure to Hg in the Aveiro region using noninvasive biological matrices; ii) examine the influence of variables that may contribute to Hg exposure during pregnancy; and iii) improve knowledge regarding metal accumulation and distribution over the maternal-fetal-placental unit...

We are rapidly becoming an aging society, with the ongoing increase in challenges of the elderly. The age-related cognitive decline in accordance with aging society is of major importance in public health. Recent studies have proved the impacts of sex-steroid hormone on the brain; compliant with aging, menopause and decrease in estrogen have an effect on the occurrence and prevention of Alzheimer's disease. A new hypothesis states that Alzheimer's disease is a postmenopausal dementia, and is a negative form of estrogen deficiency...

The concept of Regenerative Medicine combined with Cell based Therapy and Tissue Engineering represents the fourth pillar of healthcare and provides a promising approach for the treatment of serious diseases. Recently, cell based therapies are focused on the use of mesenchymal stem/stromal cells (MSCs). Human MSCs, that represent a mesoderm derived population of progenitors, are easily expanded in culture. They are capable to differentiate into osteoblasts, chondrocytes, and adipocytes and exhibit the potential to repair or regenerate damaged tissues...

Monocytes give rise to macrophages and dendritic cells (DCs) under steady-state and inflammatory conditions, thereby contributing to host defense and tissue pathology. A common monocyte progenitor (cMoP) that is strictly committed to the monocyte lineage has been recently identified in mice. Here, we identified human cMoPs as a CLEC12A(hi)CD64(hi) subpopulation of conventional granulocyte-monocyte progenitors (cGMPs) in umbilical cord blood and in bone marrow. Human cMoPs gave rise to monocyte subsets without showing any potential for differentiating into myeloid or lymphoid cells...

Objective. Human umbilical cord mesenchymal stem cells (hUC-MSCs) potentially differentiate to various types of cells including neuron-like cells. The natural polyphenol resveratrol benefits patients with many diseases including ischemic brain injury. We hypothesize that resveratrol induces differentiation of hUC-MSCs into neuron-like cells. Methods. Flow cytometry was used to determine the surface antigens in different stage of hUC-MSCs (P2, P5, and P10). Nestin, neuron-specific enolase (NSE), and glial fibrillary acidic protein (GFAP) were detected by immunocytochemistry, Western blotting, and real time RT-PCT...

Revised methods to derive, expand, and characterize mesenchymal stromal cells (MSCs) from the umbilical cord are provided. Several considerations are taken for GMP compliance including using a closed system isolation method and eliminating several xenogenic components. With this method cells are isolated using mechanical and enzymatic digestion and then expanded with high viabilities that retain >90% viability after cryopreservation. Lastly, characterization methods have been optimized to identify these cells as MSCs according to the ISCT minimal criteria...

"Fetal Origins of Adult Diseases" (FOAD) or "Barker hypothesis," also known as the developmental origins of health and diseases (DoHaD), was initially proposed by David Barker in the 1980s. Progress in past 2 to 3 decades demonstrated that many adult disorders, including hypertension, diabetes, obesity, cancer, and others, could be linked to poor development resulting from in utero insults. Utero-environments play a critical role in fetal development. Because the placenta and umbilical cord are the only important connections between the fetus and mother in the uterus, this review pays special attention to recent research and progress in the study of the relationship between those tissues and FOAD...

Intraventricular hemorrhage (IVH) is a frequent complication of preterm newborns, resulting in cerebral palsy and cognitive handicap as well as hypoxic ischemic encephalopathy and periventricular leukomalacia. In this study, we investigated the restorative effect on neonatal IVH by umbilical cord-derived mesenchymal stromal cells (UC-MSCs) cultured in serum-free medium (RM medium) for clinical application. UC-MSCs were cultured with αMEM medium supplemented with FBS or RM. A neonatal IVH mouse model at postnatal day 5 was generated by intraventricular injection of autologous blood, and mice were intravenously administered 1×10(5) UC-MSCs two days after IVH...

BACKGROUND: A recent study has shown that it is possible to accurately estimate gestational age (GA) at birth from the DNA methylation (DNAm) of fetal umbilical cord blood/newborn blood spots. This DNAm GA predictor may provide additional information relevant to developmental stage. In 814 mother-neonate pairs, we evaluated the associations between DNAm GA and a number of maternal and offspring characteristics. These characteristics reflect prenatal environmental adversity and are expected to influence newborn developmental stage...

Mitochondria are the central hubs for cellular bioenergetics and are crucial to cell survival. It is well accepted that compromised mitochondrial function is linked with hepatocytes injury and contribute to progression of liver diseases. Despite the therapeutic potential of mesenchymal stem cells (MSCs) transplantation on hepatic disorders have been extensively investigated, the effects of MSCs on mitochondrial function in liver injury models remain unknown. Here we investigated the effects of treatment with umbilical cord (UC) MSC in a rat model of D-Gal induced liver injury, characterized by organ damage, oxidative stress and mitochondrial dysfunction...

H19 is a tumor-suppressor gene, and changes in the methylation of the H19-differential methylation region (H19-DMR) are related to human health. However, little is known about the factors that regulate the methylation levels of H19-DMR. Several recent studies have shown that maternal environmental factors during pregnancy, such as smoking, drinking, chemical exposure, and nutrient intake, can alter the methylation levels of several genes in fetal tissues. In this study, we examined the effects of maternal factors on changes in the methylation levels of H19-DMR in the human umbilical cord (UC), an extra-embryonic tissue...
