Vincent Michael Alford
Postdoctoral Research Fellow, Stem Cell Biology and Regenerative Medicine
Current Research and Scholarly InterestsMy interest in science and research was fostered at a young age after losing a family member to colorectal cancer. At that young age, it was made apparent to me that cancer remains poorly understood which is reflected in the total lack of target-specific treatment regiments available to this patient population. This disparity in patient care is what inspired me to pursue a Ph.D in Molecular and Cellular Pharmacology at Stony Brook University (SBU). During my time at SBU, my dissertation research focused on the development of a standard approach for rational drug design against the functional activity of individual matrix metalloproteinases (MMPs). Results from this work led to the successful development of the first small molecule inhibitor specifically targeting the hemopexin domain of MMP-9. Additionally, I was also given the opportunity to assist in the development of a cell based High-Throughput Screen assay for the identification of small molecules with activity against cancer cell invasion.
After obtaining my Ph.D, I pursued a postdoctoral scholar position at Stanford University within the Institute of Stem Cell Biology and Regenerative Medicine. Currently, my projects have slowly become broader and more focused around protein chemistry. More specifically, my research interest lies in identifying protein targets or cell populations responsible for chronic illnesses such as Triple Negative Breast Cancer and Alzheimer’s disease. After identifying the target, my passion lies in understanding the biological function of said target in various biological signaling cascades and cell niche population maintenance. Another area I specialize in is assigning function to the various domains of individual proteins and prioritizing drug development against the most promising targets. Upon identification of the target and validation of the domains responsible for protein activity- it becomes my mission to develop specific inhibitors against them. To this end, I use techniques such as protein mutagenesis, expression, and purification systems in addition to x-ray crystallography and chemical-protein structure activity relationships to understand, rationally design, and optimize these small molecule inhibitors for potential use in clinical trials. -

Lay Teng Ang
Instructor, Institute for Stem Cell Biology and Regenerative Medicine
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. -

Kyle Loh
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.

Gernot Neumayer
Postdoctoral Research Fellow, Stem Cell Biology and Regenerative Medicine
Current Research and Scholarly InterestsMy MSc project, carried out at the University of Salzburg in cooperation with the biotechnology company ProComCure, investigated the molecular interface between human cells and the bacterium Staphylococcus aureus. S. aureus exhibits a dramatic increase in resistance to antibiotics, thereby causing enormous challenges for health care. Using proteomics platforms, I identified numerous novel host-pathogen interactions. These findings are being developed further by ProComCure in order to design innovative therapies for S. aureus infections.
My dissertation project, carried out at the University of Calgary, defined the functions of the human protein TPX2. TPX2 has been discovered over 17 years ago for its unique property to mediate cell division. However, when not involved in cell division TPX2 resides in the cell nucleus where its role had remained unknown. Building on my background in proteomics, I discovered a novel TPX2-containing protein complex that resides in the nucleus. Analysis of this complex unraveled a completely unexpected role for TPX2 in cellular reactions triggered by insults to DNA. To avoid cancers, cells respond to damaged DNA by either attempting its repair or, if this is not possible, by committing 'suicide'. My findings established that TPX2 impacts the molecular mechanisms that underlie these responses to DNA damage. More specifically, I found that TPX2 accumulates at DNA lesions and that the cellular levels of TPX2 negatively correlate with the ‘strength’ of the DNA damage response. Thus, TPX2 affects cellular proliferation, DNA repair, and survival upon genomic insult. This was the first function discovered for TPX2 in the cell nucleus. Since abnormally high levels of TPX2 are often found in human cancers, my discovery sheds light on the mechanistic implication of this protein in carcinogenesis. Furthermore, TPX2 is also a promising therapeutic target and my findings may advance novel cancer therapies. We propose that future treatments may attempt to reduce TPX2 levels in order to increase the strength of the DNA damage response. Subsequently, chemo- and radiotherapy doses may be lowered but still stay effective.
In 2014, I joined the Wernig laboratory at Stanford University. Here, I capitalize on my expertise in mechanisms of DNA damage response to develop a pioneering technique capable of repairing pathogenic mutations in the genetic material of patients suffering from Epidermolysis Bullosa (a devastating and often lethal disease that causes chronic erosion of the skin). This novel technique, called CRISPR, introduces experimentally controlled and transient damage to the mutated DNA of patient cells and exploits naturally occurring DNA repair mechanisms to transform the disease-causing mutation to a normal state. I will combine development of CRISPR with Dr. Wernig’s expertise in regenerative medicine to generate patient derived stem cells with repaired (i.e. normal) genes. Subsequently, these stem cells will be employed to regenerate the skin of Epidermolysis Bullosa patients. -

Roeland Nusse
Virginia and Daniel K. Ludwig Professor in Cancer Research and the Reed-Hodgson Professor in 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.
