Research Interests

Our research activity is focused on the molecular basis of stem cell pluripotency and lineage specification in mammals. The main interest of our laboratory is to understand how to direct stem cell differentiation along specific pathways and to develop molecular tools to target tumour initiating cells.  Toward this end, we are engaged in three related projects

Regulation of pluripotent stem cell differentiation by Cripto and Cripto-responsive genes. Most of our research activity is centred on the signalling molecule Cripto, a modulator of members of TGF-β family, which was originally discovered by Graziella Persico at the IGB. In addition to investigating the fundamental biology of mouse ESCs, we are developing molecular tools to target Cripto signalling and improve the use of stem cell-based therapy in neurodegenerative diseases, such as Parkinson’s disease.

Unravelling the role of Cripto in adult tissue regeneration. We discovered that Cripto is re-expressed during muscle regeneration and it is a regulator of the muscle stem cell compartment. We are performing basic molecular studies, both in vitro and in vivo, to unravel the precise nature of Cripto signalling in skeletal muscle regeneration and developing molecular tools to assess the potential therapeutic value of Cripto in alleviating muscle diseases.

Metabolic control of stem cell plasticity. It is now becoming evident that metabolism is a key regulator of stem cell plasticity that has been largely overlooked so far. We have recently contributed to this emerging field showing that the nonessential amino acid (NEAA) L-Proline (L-Pro) acts as an epigenetic signal and is a key regulator of mouse ESC metastability. We are currently investigating the molecular connection between L-proline metabolism and epigenetic modifications in the control of stem cell identity.
