development and transcriptional control findings
We use mouse embryonic stem cells to study cell identity control mechanisms using a range of quantitative techniques (c.f. Amblard et al., 2024). We also benchmark the cell types we generate in vitro against their in vivo counterparts using mouse embryos (c.f. Metzis et al., 2018).

We apply genome engineering approaches (such as CRISPR-Cas9) to understand how regulatory elements function during development (c.f. Amblard et al., 2024).
ATAC SEQ diagram
By directing the differentiation of embryonic stem cells, together with genome-wide approaches such as ATAC-seq, we have resolved molecular events that drive spinal cord formation (c.f. Metzis et al., 2018; Semprich et al., 2022).

Development and transcriptional control Research

“How do cells develop during early development?” 

During embryonic development, different cell types will form to make up the body. But how does an embryo produce the right cell type, at the right position? Our group is examining how this processed is controlled. These insights are critical to understand how congenital diseases develop, including cancer, and are relevant for developing appropriate therapies, spanning tissue engineering and regenerative medicine.

The ability to make different cell types relies on the activity of different genes. Our lab is studying the control mechanisms that drive differential gene activity. To do this, we study the function of enhancers – discrete regions of the genome that act as molecular “switches” that help to determine where and when a gene is expressed. By studying enhancer function, we aim to explain how different cell types develop.

To achieve these goals, we use embryonic stem cells to study how different cell types develop in vitro, using mouse models to resolve how this translates in an in vivo setting. We combine these approaches with genome engineering and computational biology to define how different cell types are controlled by enhancers through the actions of different signalling cues that are perceived and interpreted by cells.

Understanding how cell identity is controlled holds the potential to address a range of biomedical questions, including how we have evolved to produce the wide array of cell types that make up the human body.

Defining the molecular basis of cell identity

Our lab is uncovering how diversity in cell identity arises during embryonic development. By exploring how cells take on distinct identities in the head versus the trunk of the body plan, we’ve made groundbreaking discoveries about the regulatory mechanisms that drive these regional differences. Our research has revealed crucial roles mediated by non-coding DNA elements, like enhancers, in regulating gene activity and directing cell identity, providing fundamental insights into the molecular processes that shape the body.

Our ambition is to define the molecular principles that determine cell type identity and diversity during development, by addressing key questions:

  • How do different cell types emerge in different parts of the body?
  • How do regulatory elements control cell identity and future lineage decisions?
  • How can we exploit these molecular principles to engineer specific cell types on demand from pluripotent cells?

By developing strategies to engineer precise cell types, we aim to contribute valuable insights across fields spanning development, disease modelling and regenerative medicine.
