Alessandra Sacco's Research Focus
Childhood Diseases, Muscular Dystrophy, Sarcopenia/Aging-Related Muscle Atrophy
Skeletal muscle wasting is a devastating pathology that occurs in several human conditions, including muscular dystrophies, aging, HIV. There is currently no cure for it. Muscle stem cells offer great promise for future therapies, but their use is currently limited by our poor understanding of the regulatory mechanisms directing their behavior. We are interested in understanding how extrinsic and intrinsic factors regulate muscle stem cells in vivo. Current projects include: (1) Developing stem cell-based strategies for treating muscle wasting diseases, (2) Understanding how aging affects the muscle stem cell compartment.
About Alessandra Sacco
Experience
Alessandra Sacco completed her studies at La Sapienza University in Rome, Italy. In 2002 Dr. Sacco joined the laboratory of Prof. Helen M. Blau at Stanford University as a postdoctoral fellow (2002-2009), where she studied cell fusion between hematopoietic cells and muscle cells, as a potential mechanism for tissue repair. Recently she defined strategies to isolate adult skeletal muscle stem cells and performed single cell transplantation experiments, providing the first definitive evidence that adult muscle stem cells are able to self-renew in vivo. She received research funding from Muscular Dystrophy Association (2006-2008). In 2010 Dr. Sacco was recruited as Assistant Professor at Sanford-Burnham Medical Research Institute.
