Amy J. Wagers is the Forst Family Professor of Stem Cell and Regenerative Biology at Harvard University [1] and Harvard Medical School, an investigator in islet cell and regenerative biology at the Joslin Diabetes Center, and principal faculty of the Harvard Stem Cell Institute. [2] She is co-chair of the Department of Stem Cells and Regenerative Biology at Harvard Medical School. [3]

Education and research

Wager started her education at Johns Hopkins University and received her B.A. in Biological Sciences and her Ph.D. in Immunology and Microbial Pathogenesis from Northwestern University in 1999. She completed her postdoctoral fellowship in the laboratory of Dr. Irving Weissman at Stanford University School of Medicine. [2]

Wagers researches intrinsic and extrinsic regulators of stem cell function and how stem cells impact tissue regeneration and aging. She has demonstrated that transplantation of satellite cells into injured, diseased, or aged muscle can lead to cell engraftment, in some cases restoring muscle function. She has also identified novel regulators (such as EGR1) of stem cell trafficking and stem cell number in bone marrow and during immune responses, and identified blood-borne proteins, such as GDF11, that in mice can reverse some of the pathological changes that occur in aging tissues. [2] She co-founded a company based on this work, Elevian in 2018 that aims to apply GDF11 to stroke and other conditions. [4] [5] There are other data, however, that indicate that GDF11 functions to inhibit muscle regeneration [6]

Two publications involving work by a postdoctoral researcher in the Wagers lab in 2008 were retracted by their other authors, one from Nature (2010) [7] and one from Blood (August 2008). [8] [9] The researcher was dismissed from the lab and later sanctioned by the U.S. Government's Office of Research Integrity (ORI), part of the Department of Health and Human Services. [10]

In 2018, Harvard Medical School announced that Wagers had accepted the position of co-chair of the Department of Stem Cells and Regenerative Biology, co-leading the Department with Chair Paola Arlotta.

<span class="mw-page-title-main">Precursor cell</span> Partially differentiated usually unipotent cell

In cell biology, precursor cells—also called blast cells—are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells. In embryology, precursor cells are a group of cells that later differentiate into one organ. However, progenitor cells are considered multipotent.

Gerald D. Fischbach is an American neuroscientist. He received his M.D. from the Weill Cornell Medical College of Cornell University in 1965 before beginning his research career at the National Institutes of Health in 1966, where his research focused on the mechanisms of neuromuscular junctions. After his tenure at the National Institutes of Health, Fischbach was a professor at Harvard University Medical School from 1972 to 1981 and from 1990 to 1998 and the Washington University School of Medicine from 1981 to 1990. In 1998, he was named the director of the National Institute of Neurological Disorders and Stroke before becoming the Vice President and Dean of the Health and Biomedical Sciences, the Dean of the Faculty of Medicine, and the Dean of the Faculty of Health Sciences at Columbia University from 2001 to 2006. Gerald Fischbach currently serves as the scientific director overseeing the Simons Foundation Autism Research Initiative. Throughout Fischbach's career, much of his research has focused on the formation and function of the neuromuscular junction, which stemmed from his innovative use of cell culture to study synaptic mechanisms.

Stimulus-triggered acquisition of pluripotency (STAP) was a proposed method of generating pluripotent stem cells by subjecting ordinary cells to certain types of stress, such as the application of a bacterial toxin, submersion in a weak acid, or physical trauma. The technique gained prominence in January 2014 when research by Haruko Obokata et al. was published in Nature. Over the following months, all scientists who tried to duplicate her results failed, and suspicion arose that Obokata's results were due to error or fraud. An investigation by her employer, RIKEN, was launched. On April 1, 2014, RIKEN concluded that Obokata had falsified data to obtain her results. On June 4, 2014, Obokata agreed to retract the papers. On August 5, 2014, Yoshiki Sasai—Obokata's supervisor at RIKEN and one of the coauthors on the STAP cell papers—was found dead at a RIKEN facility after an apparent suicide by hanging.

<span class="mw-page-title-main">Helen Blau</span> American biochemist

Helen Blau is a cell biologist and stem cell researcher famous for her work on muscle diseases, regeneration and aging. She is the Donald E. and Delia B. Baxter Foundation Professor and the Director of the Baxter Laboratory for Stem Cell Biology at Stanford University. Blau is known for overturning the prevailing view that once a cell assumes a certain specialty in the body — or differentiated state —such as a skin or liver cell, it cannot be changed. Her research established that the fate of mammalian cells can be altered. Her finding that specialized cells can be triggered to turn on genetic programs characteristic of other differentiated states provided early evidence that mammalian cellular reprogramming was possible and opened the door to the use of reprogramming in stem cell biology. Her work set the stage for the development of induced pluripotent stem cells and associated stem cell therapies.
