Multi-component systems to model the Placenta ecosystem trending idea

The maternal/fetal/placenta ecosystem is complex, with dynamic communication happening among all of the components. Leveraging tissue on a chip technologies one can envision studying interactions of decidua, maternal blood component, immune cells, placenta, etc. to systematically interrogate key interactions. I wonder whether the community feels this is feasible, and also whether iPSC blastoids would be useful in such... more »

Nothing makes sense except in the light of evolution trending idea

Like all biological structures, the placenta is the outcome of a historical evolutionary process. Thus, in order to understand the development, structure, and (dys)function of the placenta we must reconstruct the developmental evolutionary history of the maternal-fetal interface. The NICHD Human Placenta Project covers a wide breadth of research topics, but a noticeable gap is the lack of evolutionary studies that explicitly... more »

Implantable placental biochemical sensors trending idea

The real-time biolochemical millieu of the devloping placenta is completely unknown. Sensors exist to sample microscopic changes in bioactive compounds in the atmosphere (for environmental health), and small biosensors have been developed to monitor hormonal and biochemical activity in tumors, for example. While not performed in every pregnancy, chorionic villus sampling is performed during pregnancy (removal of placental... more »

Cervical trophoblast: A proxy of placental health and function in early pregnancy trending idea

There is a clear gap in our ability to investigate the placenta and pregnancy risk in the first trimester of pregnancy on a cellular level.

It is well established that protein expression is different in placental cells of pregnancies that developed placental disorders including severe preeclampsia (PE). This idea exploits the fact that the placenta naturally sheds hundreds of trophoblast cells into the cervical canal... more »

MRI and US in the assessment of placental health and disease

MR and ultrasound are listed in separate categories. However, US will always be a screening tool, used prior to MRI. When we are assessing diseases with plancetal etiologies, what is the best manner to integrate the information provided by both US and MRI. Can ultrasound be used to screen to lmiit the number of MR examinations? How is this affected by gestational age, position of the placenta with respect to maternal... more »

Womb with a View

This is such an exciting arena of work and advancement. While the arena of the "placental microbiome" has nearly garnished more editorials than original research, their continues to be more original and well controlled research demonstrating a low biomass, low abundance metagenomically identifiable community that is distinguishable from contaminant controls. Irrespective of which side of the "great sterility debate" it... more »

Placental cell units and integrated funtions trending idea

Understanding the placenta from the cell unit constitution and the detailed cell diversity using new tools such as single cell approaches. The complexity of placental functions as a result of the integrated interaction between all trophoblasts subtypes, there is a big gap on the knowledge regarding the exact placental cellular diversity and individual functions (functional nodes). What we know so far and which are the... more »

The Human Placenta Project

Failed to die or failed to invade ?

Spiral artery remodeling is essential step of establishing uteroplacental circulation in human pregnancy. In early pregnancy, extravillous trophoblasts invade into maternal spiral artery, forming endovascular trophoblast plugs, and these endovascular trophoblasts undergo a phenotypic switch to express CD56, a NK cell marker. Little effort is made to understand what happen to these endovascular trophoblasts after initial... more »

Correlation between Development of Placenta and the Fetal brain

The hypothesis is that a symbiotic relationship exists between the placenta and the fetal brain. A healthy placenta leads to healthy brain development in the fetus. Studies are warranted to find the correlation between the placenta and the fetal brain and the various clinical biomarkers and circulating factors aiding this process and the hypoxia-ischemia pathway

Human placenta innate immunity

The human placenta is unique among mammals. We lack understanding of its immune complex and the innate responses that prevent or enable vertical transmission. The COVID pandemic highlights this gap. Where previous coronavirus outbreaks were associated with adverse pregnancy outcomes, SARS-Cov-2 does not appear to pass the placenta and negatively impact fetal development. Interestingly, several groups have highlight SARS-Cov-2... more »

Supporting People with Disabilities trending idea

The National Center for Medical Rehabilitation Research (located within the NICHD) would like to highlight three issues that may arise in the context of the Human Placenta Project:

β€’ Ensure that people with disabilities (PWD) are included among the subject populations – and special efforts are made to support their reproductive health and opportunities. Often, PWD are not asked about reproductive health and are not offered... more »

Simultaneous maternal and fetal blood flow assessment in the placenta using umbilical vein Doppler

A big issue in assessment of placental abnormalities in vivo is that the placenta has two separate blood supplies, maternal and fetal. Presently, there are no easy ways to directly assess these contributing flows at the same time. If there were such a method, it could greatly enhance placental evaluation in a myriad of ways. For instance, it would be possible to show the effects of various therapies on both the maternal... more »

Human Umbilical Cord Development

Very little is known about development of the human umbilical cord and insertion into the fetal abdominal wall, yet developmental abnormalities contribute to multiple recurring embryonic malformations, including limb-body wall complex, pentalogy of Cantrell and OEIS (omphalocele, exstrophy of bladder or cloaca, imperforate anus, and spinal defects). In addition, anomalies are more frequently associated with a two vessel... more »
