Lay Teng Ang
Instructor, Institute for Stem Cell Biology and Regenerative Medicine
BioAs a stem cell biologist, I aim 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 ten years has centered on pluripotent stem cells (PSCs, which include embryonic and pluripotent stem cells), which can generate any of the hundreds of diverse cell types in the body. However, it has been notoriously challenging 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 various 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 and bone (Loh & Chen et al., 2016; Cell) and liver (Loh & Ang et al., 2014; Cell Stem Cell) from PSCs. My laboratory currently focuses on differentiating human PSCs into liver progenitors (Ang et al., 2018; Cell Reports) and blood vessel cells (Ang et al., 2022; Cell).
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. I then moved my laboratory to Stanford University as a Siebel Investigator and Instructor at the Stanford Institute for Stem Cell Biology & Regenerative Medicine. My laboratory has been supported by the Siebel Investigatorship, California Institute for Regenerative Medicine, and other sources. -

The Ernest and Amelia Gallo Professor, Professor of Urology, of Developmental Biology and, by courtesy, of Chemical and Systems Biology
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.

Natalia Gomez-Ospina
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.

Tal Gordon
Postdoctoral Scholar, Stem Cell Biology and Regenerative Medicine
BioI am a zoologist and molecular biologist interested in the molecular basis of regeneration. My research focuses on stem cells and regeneration in ascidians, a group of marine invertebrates that represent the closest living relatives of the vertebrates. One of the main questions that motivate my research is whether regeneration capabilities lost during evolution can, at least to some extent, be re-acquired. As regeneration is not universal in the animal kingdom, I hypothesize that comparing regeneration in species with distinct regenerative capacities will lead to the discovery of key components of regeneration.
During my postdoc I intend to use comparative genomics to identify conserved cellular and molecular mechanisms that underlie ascidians’ regeneration. -
Stefan Heller
Edward C. and Amy H. Sewall Professor in the School of Medicine and Professor of Otolaryngology - Head & Neck Surgery (OHNS)
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 in 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 ways to regenerate lost sensory hair cells in mammals.

Siddhartha Jaiswal
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.
