Riassunto dell'attività scientifica
Research in Dr. Blau's laboratory is focused on understanding principles of regenerative medicine. Her laboratory established that the differentiated state of specialized tissue-specific cells is not fixed and irreversible, but can be changed. This demonstration of cellular plasticity constituted a paradigm shift in our understanding of mammalian cell differentiation. Using muscle as a model, Blau's work provided the first definitive evidence that diverse cell types could be reprogrammed using non-dividing cell fusions. Her studies demonstrated that cell differentiation requires continuous regulation and that a shift in the stoichiometry of trans-acting regulators induces nuclear reprogramming. This body of work provided the scientific underpinnings for the induction of pluripotent stem cells. Blau applied this discovery to adult stem cell biology. She led the field with novel approaches to the isolation of muscle stem cells, maintenance of stem cell function on bioengineered platforms, and strategies for rejuvenating aged stem cell function. Her work provides the foundation for innovative stem cell based strategies to treat skeletal and cardiac disorders due to injury, disease or aging. Blau's research is at the crux of stem cell biology and regenerative medicine.
