Helen Margaret Blau, Ph.D. is an internationally recognized American biologist and the Donald E. and Delia B. Baxter Foundation Professor and Director of the Baxter Laboratory for Stem Cell Biology at Stanford University School of Medicine. She is known for establishing the reversibility of the mammalian differentiated state. Her landmark papers showed that nuclear reprogramming and the activation of novel programs of gene expression were possible, overturning the prevailing view that the differentiated state was fixed and irreversible. Her discoveries opened the door for cellular reprogramming and its application to stem cell biology.
Helen Blau was born 1948 in London and is a dual citizen of the United States and Great Britain. She earned a B.A. from the University of York in England and an M.A. and Ph.D. in biology from Harvard University with Fotis C. Kafatos. After a postdoctoral fellowship with Charles J. Epstein in the Departments of Biochemistry and Biophysics and the Division of Medical Genetics at UCSF, she joined the faculty at Stanford University in 1978. She was awarded an endowed chair in 1999 and named Director of the Baxter Laboratory for Stem Cell Biology in 2002.
Blau is known for her support of women in science and success in mentoring numerous young scientists who comprise the next generation of academic leaders in muscle biology and regenerative medicine.
In the 1980s Dr. Blau's findings challenged the prevalent view that the mammalian differentiated state is fixed and irreversible. In her famous heterokaryon experiments she fused differentiated cells of two different species to form stable non-dividing heterokaryons, and found that previously silent genes could be activated. As a result, human keratinocytes, hepatocytes and fibroblasts expressed muscle genes that they normally never would. This body of work showed that the differentiated state requires continuous regulation and that a shift in the stoichiometry of trans-acting regulators induces nuclear reprogramming to another differentiated state. Her discoveries fostered the development of the field of stem cell biology and regenerative medicine.
Blau characterized muscle stem cells and showed they are dysfunctional in aging and in muscular dystrophy. She showed that stem cells lose their regenerative potential when grown in traditional plastic dishes and overcame this limitation by fabricating bioengineered microenvironments that mimic crucial stem cell niche and tissue properties. She has applied this approach to identify molecules that rejuvenate the function of the aged stem cell population and enhance muscle regeneration.
Blau showed that telomere dysfunction in conjunction with dystrophin deficiency plays a central role in the skeletal muscle wasting and fatal cardiomyopathy characteristic of Duchenne muscular dystrophy. Her lab's novel technologies enable rapid, transient and robust elongation of telomeres to overcome cellular dysfunction due to short telomeres, which have translational applications.
Dr. Blau's lab applied evolutionary lessons from newts and salamanders that regenerate limbs to identify genes that constitute barriers to regeneration. By transiently alleviating these brakes on the cell cycle, post-mitotic cells are induced to divide, reconstituting a regenerative cell source.
A hallmark of Blau's research is the development and application of novel technologies. Her discovery of β-galactosidase complementation is widely used in drug discovery. Non-invasive bioluminescence imaging enables highly sensitive temporal and spatial resolution of muscle stem cell regenerative function in vivo. Using single cell lineage tracking and the Baxter algorithms her lab developed, cell morphology, movement, cell-cell interactions, division behavior and gene expression can be dynamically monitored, resolving the cellular basis for population changes, in response to pharmacologic interventions. She has eight issued US patents.
Dr. Blau's ongoing research focuses on cellular reprogramming, therapeutic interventions to enhance stem cell function in muscle regeneration, and cell rejuvenation strategies.

Professor Blau was born in England, spent her early childhood in the U.S. and then lived in Europe until she moved to the United States for graduate school. She speaks French and German. Her father, George E. Blau, was Chief historian for the U.S. Government in Europe and her mother Gertrud M. Blau was an instructor of comparative literature at Heidelberg University and they strongly encouraged Helen and her sister Professor Eve Blau, now on the faculty at Harvard University, to pursue higher education. She is married to Professor David Spiegel, a research psychiatrist at Stanford University, and they have two children, Daniel Blau Spiegel, an architect, and Julia Blau Spiegel, a lawyer. Professor Blau and her husband are avid scuba divers and skiers.
