Research Interests

Cells with the capacity to produce all adult tissues, including the germ line, can be propagated in culture from the early epiblast in the form of naïve pluripotent embryonic stem (ES) cells. ES cell derivation from mouse embryos is very efficient in defined medium with inhibitors of FGF signalling and GSK3, which together prevent differentiation and promote expansion of the epiblast. Although pluripotent cell lines have been derived from other mammals, these differ from murine ES cells, and are more similar to the primed pluripotent epiblast stem cells obtained from post-implantation mouse embryos. We are currently optimising conditions to capture naive pluripotent stem cells from non-rodent mammalian embryos using a modified version of the mouse ES culture regime.

How the pluripotent lineage is established during development is also an interesting question, which we address using molecular and genetic approaches incorporating mouse lines with specific and inducible deletions in key pluripotency factors. We quantify transcripts using single cell technology and proteins by quantitative immunofluorescence. Conditional deletion mutants provide a valuable system with which to explore the temporal requirement for factors of interest during entry and exit from pluripotency and lineage priming. ES cells maintain a molecular profile closely related to the early epiblast from which they originate. They also retain the capacity to integrate into preimplantation embryos. We exploit this phenomenon to challenge the host embryo to react to the influx of epiblast cells and monitor its response in terms of selective elimination or modification of lineage decisions. Microinjection, live imaging and immunohistochemistry comprise the main tools for this project.

In collaboration with Wolf Reik and members of the Wellcome Trust Strategic Award consortium for single cell technology, we are exploring the molecular properties (currently transcriptome and methylome) of single embryo cells during cell lineage decisions, exit from pluripotency and gastrulation. We wish to understand when and how cells commit to specific tissues, identify lineage-specific molecular motifs and investigate the roles of heterogeneity of expression and cell-cell communication.

Full list of publications

Plain English

In the early stages of mammalian development specialised tissues are rapidly generated to allow implantation and connection with the mother. The foetus forms from a separate population of cells called the epiblast that can respond appropriately to signals to form the structures of the foetus in the right time and place. Under suitable culture conditions the epiblast can be captured in a 'self-renewing' state, in the form of embryonic stem cells (ESCs). These can be grown practically indefinitely whilst retaining the ability to form all tissues of the body. They can also be genetically modified to create disease models and investigate gene function. Our lab studies the process of ESC derivation and epiblast function during embryogenesis to satisfy our curiosity and as a means to understand the causes of early developmental failure.
