OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

...pment problems. Specifically, nicotine crosses the placenta where it interacts with cells in the unborn infant's developing lungs. While past research in the Spindel lab has helped define how nicotine causes these changes, many of the specific mechanisms for infant lung development problems remain unknown. H...

Discarded placentas deliver researchers promising cells similar to embryonic stem cells

... publication in Stem Cells Express. A part of the placenta called the amnion, or the outer membrane of the amniotic sac, is comprised of cells that have strikingly similar characteristics to embryonic stem cells, including the ability to express two key genes that give embryonic stem cells their unique capab...

Baby's genes affect mom's cholesterol levels

Study uncovers placental microtransfusions lead to transmission of AIDS virus during childbirth

Liquid ventilation

... being born we carry this activity out through the placenta and subsequently by means of our lungs. In normal development, the lungs of the foetus are filled with amniotic liquid and, on being born, the first cry activates this respiration surface. But the main problem that premature babies have is that their...

Hair samples show babies can be exposed to 'crystal meth' while in the womb

...hed, indicating that the drug is able to cross the placenta directly to the developing fetus, say the authors. Only one newborn had no evidence of the drug in its hair. Fetal hair starts to grow at about 20 weeks. The authors say that the precise effects of crystal meth on a fetus are not fully known,...

This suggests that the markers are specific to tumors and would not be mistaken for normal blood vessel growth in women of reproductive age.
