Centre for Trophoblast Research



Thorsten originates from Austria, where he studied Molecular Biology at the University of Vienna. After completion of his master’s thesis in 2007, he was awarded a PhD-fellowship at the University of Sheffield to work on neuronal differentiation of mouse embryonic stem cells. Thorsten early postdoctoral work in the laboratories of Prof. Austin Smith and Prof. Jennifer Nichols provided transcriptional and functional evidence that the closest in vivo counterpart of mouse embryonic stem cells is the preimplantation epiblast. Between 2012 and 2015, he pioneered genome-wide comparison of mouse to non-human primate development by lineage-specific RNA-seq, which identified a primate-specific role for WNT signaling during early lineage specification. In 2017, Thorsten was awarded a Sir Henry Dale Fellowship to start his own group – the Laboratory for Primate Embryogenesis – at the Department of Physiology, Development and Neuroscience at the University of Cambridge. Thorsten is a member of the Cambridge Stem Cell Institute, the Centre for Trophoblast Research, the Anne McLaren Trust Fund and Fellow of Darwin College.


Embryo implantation, gastrulation and organogenesis

The first signs of the human body axis can be traced back to the second week of gestation. To get to this point, the blastocyst implants and establishes a small sheet of cells, the embryonic disc. Deeply embedded within extraembryonic tissues, the embryo undergoes a reorganization process termed “gastrulation”, which transforms the embryonic disc into three germ layers and determines the entire future body plan.

Most of our knowledge on mammalian gastrulation is based on mouse, but human embryogenesis differs in anatomical architecture, timing, molecular configuration and sequence of cell-fate decisions. For instance, in human and non-human primates, the implanting epiblast polarises into a rosette, gives rise to amnion and forms a flat EmDisc. Rodent embryos form amnion later in development, after gastrulation.

Research goals

The central aim of our research focuses on delineating the molecular crosstalk between the human embryonic disc and extraembryonic signalling centres, which control the sequence of cell-fate allocation in the primitive streak. To understand how these signalling centres emerge, we need to elucidate how extraembryonic lineages are specified in primate postimplantation development.

Our lab was the first to reveal the molecular landscape in primate embryos between implantation and gastrulation in vivo (Bergmann et al., Nature 2022). We developed epiblast- and amnion-spheroid cultures using microfluidics (Schindler et al., Stem Cell Reports 2021; Munger et al., Development 2022) and pioneered computational approaches, including spatial-identity-mapping, to determine the identity of in vitro cultured cells. Our ongoing work involves micropatterning, blastoids, microfluidics and bioprinting to emulate human and non-human primate development in stem cell-based embryo models.

The results from our work will be critical to understand human implantation failure, how errors in gastrulation can lead to congenital malformations and how germ layers are patterned for organ formation.
