BioAs a stem cell biologist, my overall goal is to understand the mechanisms through which stem cells differentiate into progressively-specialized cell-types and to harness this knowledge to artificially generate pure populations of desired cell-types from stem cells. My work over the past 10 years has centered on pluripotent stem cells (PSCs, which include embryonic and pluripotent stem cells), which have the remarkable ability to generate any of the hundreds of diverse cell-types in the body. However, it has been notoriously difficult to guide PSCs to differentiate into a pure population of a given cell-type. Current differentiation strategies typically generate heterogeneous cell populations unsuitable for basic research or clinical applications. To address this challenge, I mapped the cascade of branching lineage choices through which PSCs differentiate into a variety of endodermal and mesodermal cell-types. I then developed effective methods to differentiate PSCs into specific lineages by providing the extracellular signal(s) that specify a given lineage while inhibiting the signals that induce the alternate fate(s), enabling the generation of highly-pure human heart, bone (Loh & Chen et al., 2016; Cell) and liver (Loh & Ang et al., 2014; Cell Stem Cell) from PSCs. In particular, I have focused on generating pure populations of liver progenitors from PSCs; these PSC-derived human liver progenitors regenerated human liver tissue, and improved the survival of, mouse models of liver failure (Ang et al., 2018; Cell Reports). My goal is to complete the preclinical development of PSC-derived liver progenitors as a potential cellular replacement therapy for liver failure. This project will be facilitated by my experience with PSC differentiation, assays of liver cell identity and function, and mouse models of liver failure.
I earned my Ph.D. jointly from the University of Cambridge and A*STAR and was subsequently appointed as a Research Fellow, and later, a Senior Research Fellow, at the Genome Institute of Singapore. At Singapore, I was an independent group leader and received extramural funding support as PI or co-PI on three government grants. In April 2018, I moved my laboratory to Stanford University as a Siebel Investigator and Instructor at the Stanford Institute for Stem Cell Biology & Regenerative Medicine. My laboratory is supported by the Siebel Investigatorship and two grants from the California Institute for Regenerative Medicine.

Current Research and Scholarly InterestsFunction of Hedgehog proteins and other extracellular signals in morphogenesis (pattern formation), in injury repair and regeneration (pattern maintenance). We study how the distribution of such signals is regulated in tissues, how cells perceive and respond to distinct concentrations of signals, and how such signaling pathways arose in evolution. We also study the normal roles of such signals in stem-cell physiology and their abnormal roles in the formation and expansion of cancer stem cells.
Michael F. Clarke, M.D.
Karel H. and Avice N. Beekhuis Professor of Cancer Biology
Current Research and Scholarly InterestsDr. Clarke maintains a laboratory focused on two areas of research: i) the control of self-renewal of normal stem cells and diseases such as cancer and hereditary diseases; and ii) the identification and characterization of cancer stem cells. His laboratory is investigating how perturbations of stem cell regulatory machinery contributes to human disease. In particular, the laboratory is investigating epigenetic regulators of self renewal, the process by which stem cells regenerate themselves.
Assistant Professor of Pediatrics (Stem Cell Transplantation)
Current Research and Scholarly InterestsDr. Czechowicz’s research is aimed at understanding how hematopoietic stem cells interact with their microenvironment in order to subsequently modulate these interactions to improve bone marrow transplantation and unlock biological secrets that further enable regenerative medicine broadly. This work can be applied across a variety of disease states ranging from rare genetic diseases, autoimmune diseases, solid organ transplantation, microbiome-augmentation and cancer.
Associate Professor of Medicine (Pulmonary and Critical Care)
Current Research and Scholarly InterestsWe investigate the cellular and molecular events that regulate proper development of the lungs, including how the gas exchange region is maintained and renewed throughout life. We apply this knowledge to dissect how dysregulation of these normal processes can cause or contribute to specific lung diseases like pulmonary fibrosis, emphysema, and lung cancer, and we are interested in uncovering how lung stem cells are regulated in the hopes of harnessing them as a regenerative therapy for patients.
Maximilian Diehn, MD, PhD
Associate Professor of Radiation Oncology (Radiation Therapy)
Current Research and Scholarly InterestsMy laboratory focuses on two main areas: 1) cancer stem cell biology and 2) novel biomarkers for identifying the presence of malignant cells (diagnostic), predicting outcome (prognostic), and predicting response to therapy (predictive). Areas of study include cancers of the lung, breast, and gastrointestinal system. Clinically I specialize in the treatment of lung cancer and applications of stereotactic ablative radiotherapy and perform both prospective and retrospective clinical studies.
Assistant Professor of Pediatrics (Genetics) and of Pediatrics (Stem Cell Transplantation)
Current Research and Scholarly InterestsDr. Gomez-Ospina is a physician scientist and medical geneticist with a strong interest in the diagnosis and management of genetic diseases.
1) Lysosomal storage diseases:
Her research program is on developing better therapies for a large class of neurodegenerative diseases in children known as lysosomal storage disorders. Her current focus is on developing genome editing of hematopoietic stem cells as a therapeutic approach for these diseases beginning with Mucopolysaccharidosis type 1 and Gaucher disease. She established a genetic approach where therapeutic proteins can be targeted to a single well-characterized place in the genome known as a safe harbor. This approach constitutes a flexible, “one size fits all” approach that is independent of specific genes and mutations. This strategy, in which the hematopoietic system is commandeered to express and deliver therapeutic proteins to the brain can potentially change the current approaches to treating childhood neurodegenerative diseases and pave the way for alternative therapies for adult neurodegenerative disorders such as Alzheimer’s and Parkinson’s disease
2) Point of care ammonia testing
She also works in collaboration with other researchers at Stanford to develop point-of-care testing for serum ammonia levels. Such device will greatly improve the quality of life of children and families with metabolic disorders with hyperammonemia.
3) Gene discovery
Dr Gomez-Ospina lead a multi-institutional collaboration resulting in the discovery of a novel genetic cause of neonatal and infantile cholestatic liver disease. She collaborated in the description of two novel neurologic syndromes caused by mutations in DYRK1 and CHD4.

Current Research and Scholarly InterestsOur research focuses on the inner ear, from its earliest manifestation as one of the cranial placodes until it has developed into a mature and functioning organ. We are interested how the sensory epithelia of the inner ear that harbor the sensory hair cells develop, how the cells mature, and how these epithelia respond to toxic insults. The overarching goal of this research is to find was to regenerate lost sensory hair cells in mammals.
Assistant Professor of Pathology
Current Research and Scholarly InterestsWe identified a common disorder of aging called clonal hematopoiesis of indeterminate potential (CHIP). CHIP occurs due to certain somatic mutations in blood stem cells and represents a precursor state for blood cancer, but is also associated with increased risk of cardiovascular disease and death. We hope to understand more about the biology and clinical implications of CHIP using human and model system studies.
Assistant Professor of Developmental Biology (Stem Cell)
Current Research and Scholarly InterestsWe have developed a strategy to generate fairly pure populations of various human tissue progenitors in a dish from embryonic stem cells (ESCs). We have delineated the sequential lineage steps through which ESCs diversify into various tissues, and in so doing, developed methods to exclusively induce certain fates at the expense of others. The resultant pure populations of tissue progenitors are the fundamental building blocks for regenerative medicine.

Virginia and Daniel K. Ludwig Professor of Cancer Research and the Reed-Hodgson Professor of Human Biology
Current Research and Scholarly InterestsOur laboratory studies Wnt signaling in development and disease. We found recently that Wnt proteins are unusual growth factors, because they are lipid-modified. We discovered that Wnt proteins promote the proliferation of stem cells of various origins. Current work is directed at understanding the function of the lipid on the Wnt, using Wnt proteins as factors the expand stem cells and on understanding Wnt signaling during repair and regeneration after tissue injury.
Anthony Oro, MD, PhD
Eugene and Gloria Bauer Professor
Current Research and Scholarly InterestsOur lab uses the skin to answer questions about epithelial stem cell biology, differentiation and carcinogenesis using genomics, genetics, and cell biological techniques. We have studied how hedgehog signaling regulates regeneration and skin cancer, and how tumors evolve to develop resistance. We study the mechanisms of early human skin development using human embryonic stem cells. These fundamentals studies provide a greater understanding of epithelial biology and novel disease therapeutics.
Professor of Neurosurgery
Current Research and Scholarly InterestsMembers of the Palmer Lab study the biology of neural stem cells in brain development and in the adult. Our primary goal is to understand how genes and environment synergize in influencing stem cell behavior during development and how mild genetic or environmental risk factors for disease may synergize in their detrimental effects on brain development or in the risk of neuronal loss in age-related degenerative disease.
Sutardja Chuk Professor of Definitive and Curative Medicine
BioDr. Porteus was raised in California and was a local graduate of Gunn High School before completing A.B. degree in “History and Science” at Harvard University where he graduated Magna Cum Laude and wrote an thesis entitled “Safe or Dangerous Chimeras: The recombinant DNA controversy as a conflict between differing socially constructed interpretations of recombinant DNA technology.” He then returned to the area and completed his combined MD, PhD at Stanford Medical School with his PhD focused on understanding the molecular basis of mammalian forebrain development with his PhD thesis entitled “Isolation and Characterization of TES-1/DLX-2: A Novel Homeobox Gene Expressed During Mammalian Forebrain Development.” After completion of his dual degree program, he was an intern and resident in Pediatrics at Boston Children’s Hospital and then completed his Pediatric Hematology/Oncology fellowship in the combined Boston Chidlren’s Hospital/Dana Farber Cancer Institute program. For his fellowship and post-doctoral research he worked with Dr. David Baltimore at MIT and CalTech where he began his studies in developing homologous recombination as a strategy to correct disease causing mutations in stem cells as definitive and curative therapy for children with genetic diseases of the blood, particularly sickle cell disease. Following his training with Dr. Baltimore, he took an independent faculty position at UT Southwestern in the Departments of Pediatrics and Biochemistry before again returning to Stanford in 2010 as an Associate Professor. During this time his work has been the first to demonstrate that gene correction could be achieved in human cells at frequencies that were high enough to potentially cure patients and is considered one of the pioneers and founders of the field of genome editing—a field that now encompasses thousands of labs and several new companies throughout the world. His research program continues to focus on developing genome editing by homologous recombination as curative therapy for children with genetic diseases but also has interests in the clonal dynamics of heterogeneous populations and the use of genome editing to better understand diseases that affect children including infant leukemias and genetic diseases that affect the muscle. Clinically, Dr. Porteus attends at the Lucille Packard Children’s Hospital where he takes care of pediatric patients undergoing hematopoietic stem cell transplantation.

Assistant Professor of Pathology
Current Research and Scholarly InterestsFibrotic diseases kill more people than cancer in this country and worldwide. We believe that scar-forming cells called fibroblasts are at the core of the fibrotic response in parenchymal organ fibrosis in the lung, liver, skin, bone marrow and tumor stroma. At the cellular level we think of fibrosis as a step wise process which implicates inflammation and fibrosis. We seek to identify new effective immune therapy targets to treat fibrotic diseases.
