Cracking up the Nucleus to Unlock a Cell's Full Potential.

Cracking up the Nucleus to Unlock a Cell's Full Potential.

We study the epigenetic mechanism that determine cell identity.

Epigenetic Reprogramming lies at the heart of the earliest stages of development, at fertilization, which enables the formation of a totipotent zygote – the one-cell embryo able to give rise to all the cells of our body. 

Our research is dedicated to exploring the fascinating field of Cellular Identity and uncovering the molecular mechanisms underlying Epigenetic Reprogramming, Cell Fate, and Cellular Memory. We aim at determining how stem cells originate in vivo and at establishing the epigenetic principles behind changes in cellular plasticity and reprogramming. Our researchers study how the transitions in cell potency and cell fate are regulated by chromatin-mediated processes using a variety of approaches including quantitative imaging, modeling, functional genomics and cell biology. Understanding the molecular mechanisms behind the maintenance and manipulation of cellular plasticity will have strong implications in regenerative medicine and disease, and will help in deciphering human reproduction and infertility.

Our Research Topics

Tracking cell fates

Remembering and forgetting the past.

How do cells in our body remember which cell types they are? How can we erase this cellular memory efficiently and safely to generate any desired cell type on demand?

Cellular Plasticity and Totipotency

Master cells – cells that can make every other type of cell.

What enables a cell to make any cell type? How can we unlock this potential?

Cellular Identity Changes

Making heads and tails of embryos.

How do cells self-organize so that they migrate together? How do they “talk” to the other cells and instruct them to adopt different fates, based on their position?

Building the Nucleus

Fitting it all in the right place, at the right time.

How do cells fit the 2 meter of our DNA in the tiny nucleus? How is the DNA packaging established at the beginning of embryonic development? 

Genome Conflicts

Accidents in the nucleus: driving at high speed.

How do cells regulate and coordinate transcription and replication on our genome? Do the protein complexes collide at certain regions of the genome?
