Empa – Particles-Biology Interactions – Particlesatbarrier

Main placenta-related topics:

The aim of our group is to discover the fundamentals of (nano)particles-biobarrierinteractions (lung, intestine and the placenta). In particular, we are interested in the correlation of physicochemical particle properties with barrier uptake and translocation and their biological effects. To achieve results of high predictive value, we develop and employadvanced human in vitro and ex vivo models (ex vivo placenta perfusion, co-culture transfer model, 3D microtissues, microphysiolgical co-culture model). Our research is pivotal for the safe design and use of nanomaterials in industrial, commercial and medical applications and the protection of vulnerable populations.

Sandra Haider

After receiving my BSc from the University of Applied Sciences I started my professional career at the Reproductive Biology Unit under the lead of ao Prof. Martin Knöfler. In 2010, I obtained my MSc degree in Molecular Biology at the University of Vienna, and in 2015, I received my PhD from the Medical University of Vienna. My doctoral thesis was on critical signalling pathways controlling trophoblast progenitor determination. Recently, I was given a permanent postdoc position and a 3-year professorship qualification agreement to establish independence and start my own program of research in Reproductive Biology.

My main research focus is to elucidate mechanism controlling cell fate decisions in human first trimester placentae. Of note, proliferation, differentiation and specific maturation of human epithelial and non- epithelial cells is a critical requirement for proper placentation during pregnancy and failures are associated with pregnancy disorders such as preeclampsia, intrauterine growth restriction and early abortion. So far, milestones in my career have been the discovery of Notch1 controlling extravillous trophoblast lineage formation (PNAS, 2016), the establishment of long-term expanding, 3D trophoblast organoids (Stem Cell Reports, 2018), as well as elucidating the mechanism of cilia formation in endometrial gland organoids (Endocrinology, 2019).

Rohan Lewis

I have been studying the placenta for almost 25 years and have published on placental transport, metabolism, and ultrastructure, as well as placenta’s sensing of the maternal environment and its role in the Developmental Origins of Health and Disease. My work applying mathematical modelling to placental transport studies, has provided insights into the transport of amino acids, lipids, cortisol and pharmacological drugs. The application of 3D imaging to the placenta, particularly serial block-face scanning electron microscopy has provided new insights into placental structure in the human placenta and I am now applying this 3D approach to comparative placentology.

I have been an active member of the placental community since my first IFPA in 2001. I have been on the editorial board of Placenta and my contributions as a reviewer for the journal have been recognised by “Excellence in Reviewing” awards in 2014 and 2018. I have also been actively involved in the European Placental Perfusion Workshop, which I was helped organise in 2011, 2020 and 2021. As part of the European Union funded Early nutrition project and a Leverhulme Trust funded comparative placentology project I have collaborated with researchers from across Europe.

Christiane Pfarrer

Christiane Pfarrer graduated as veterinarian in Germany in 1989 and joined the Anatomy Department of the Justus-Liebig-University Giessen in 1992 where she also graduated as Dr. med. vet. in the same year. She started her “placenta life” by studying placental vascularization comparatively in the group of Prof. Rudi Leiser. Several research visits to other universities (University of Copenhagen, Loma Linda University, Texas A&M University) improved her knowledge. Later she focused on histologically characterizing the feto-maternal interaction especially, but not exclusively, in bovines. This work resulted in her habilitation in 2004. From that point, she (together with her group) developed in vitro models for embryo-maternal communication in bovines. Career wise, she became Chair of Anatomy at the Institute for Anatomy (also head of Institute) of the University of Veterinary Medicine Hannover, Foundation in Germany. In Hannover, her group intensified the work on in vitro systems by developing 3-D models (organoids/spheroids) and started ultrastructural analysis and 3-D reconstruction of the bovine interhemal membrane and trophoblast giant cells.

Christiane is member of EPG since her first meeting in Spa, Belgium in 1995. In 2003 she co-organized the EPG/IFPA meeting in Mainz, Germany together with Rudi Leiser. Later she served in the EPG planning committee and was representative of EPG in the IFPA board, and subsequently Secretary of IFPA from 2012-2016. Besides, she is an active member of the European Association of Veterinary Anatomists (EAVA), where she served as treasurer, vice president (2016-21) and was elected president this year (2021). She has co-authored > 130 original articles in peer-reviewed journals.

Research Centre for Obstetrics and Gynaecology

Main placenta-related topics:

Oslo Pregnancy Biobank has since 2001 recruited women  during pregnancy/delivery (incl. placenta and decidual tissue collection) and 1-8 years after their index pregnancy. Our long term goal is to improve maternal and fetal health, and use pregnancy findings (eg. Placenta-related biomarkers) to identify individuals at excessive risk for long-term disease. We seek to determine the mechanisms linking placental dysfunction and later female cardiovascular health problems, and to identify new targets for early prevention of CVD in young women.

Another main placenta-related  topic of the group is senescent/postterm placentas and their biomarkers.

BREED – Biology of Reproduction, Environment, Epigenetics and Development

The BREED unit is a large research unit (>90 people) gathering researchers specializing in biomedical, veterinary and fundamental fields. It is primarily attached to the National Research Institute for Agriculture, Food and Environment (INRAE) but also to Paris-Saclay university (UPSAY), Versailles-Saint Quentin university (UVSQ), and The National Veterinary School of Alfort (ENVA). Its research focuses on the development of the mammalian embryo from the formation of the egg cell to birth and development to adulthood. Projects range from fundamental studies on the functioning of the genome during embryo and fetal growth to applied research on the effects of the environment at large on development in the agronomic, veterinary and biomedical fields. The scientific objective is to understand and control the mechanisms of epigenetic programming during prenatal life, leading to the birth of a healthy, fertile and robust individual, able to adapt to changes in his environment.

The unit is organized into 5 research teams supported by an administrative team and shared services and platforms. One team is specialised in placental research.

The Placenta, Environment and Programming of Phenonypes (PEPPS) team is particularly dedicated to placental function. It is composed of 10 permanent staff members, with expertise in placental and animal physiology, medical imaging, histology, morphometry, lipidology, endocrinology and cellular and molecular biology. In addition, the team develops original approaches in gestation microscopy and imaging.

Placenta groups

EPG gathers many groups working in research or in clinics or both, on human placenta but also on various animal and cellular models. The placenta of domestic and wild animals is also studied, both for veterinary purposes and to understand why this temporary organ is so variable in shape and organisation between species.

Reproductive Biology Laboratory, Amsterdam UMC, Netherlands

Main placenta-related topics:

The research of our team focusses on the functional genomics and epigenetics of proper placental development during pregnancy as this is critical for the delivery of a healthy baby. We use human models systems (trophoblast stem cells, cell lines, organoids, placental explants) to investigate these developments normally occurring in the first trimester of human pregnancy. Additionally, situations leading to a dysfunctional placenta (e.g. reduced trophoblast invasion) causing complications like pre-eclampsia and intra-uterine growth restriction are simulated, providing more insight in the origin of these events. Secondly, our team performs translational research on placental cells isolated from Pap smears collected from pregnant women to investigate if this can be used as a less invasive alternative to chorionic villous sampling to detect monogenic diseases.

Techniques & Technologies:

  • Placental cell, explant and organoid culture
  • Trophoblast Retrieval and Isolation from the Cervix (TRIC)
