Blood Builder Lab – Epigenetics of blood formation

Cristina (C) Pina, MD PhD

We are interested in regulation of cell identity. We investigate epigenetic and transcriptional regulation of normal and leukaemia blood cells, with a particular focus on the generation and maintenance of cell heterogeneity through variability of transcriptional activity, also known as transcriptional noise. We harness mechanisms of cell specification and maintenance of cell identity, to generate physiologically relevant 3D in vitro models of blood formation and study initiation of developmental leukaemias.
