Artinger

Kristin Artinger, PhD
Associate Professor
Craniofacial Biology

Research in my laboratory is directed towards an understanding of the molecular and genetic mechanisms involved in the development of the neural crest. Neural crest cells are born at the neural plate border and have the extraordinary ability to retain stem cell-like characteristics. Once specified, they migrate through the embryo and give rise to a diverse array of derivatives, including peripheral neurons and glia, pigment cells and craniofacial cartilage, which form most of the vertebrate face. Thus, the neural crest is an attractive model system to study the gene regulatory networks involved in cell fate determination

Identification of melanocyte populations that emerge during NBUVB treatment of human vitiligo

Vitiligo is a depigmentation disorder characterized by white patches of the skin, the result of pigment cells loss in the epidermis. Narrow Band UVB (NBUVB) is the most effective treatment to reverse vitiligo, working by inducing in epidermis the repopulation with stem cells from the hair follicle. The current project aims to identify, in the human vitiligo skin, the melanocyte populations and their migratory, proliferative and differentiation ability augmented by NBUVB light. To accomplish this goal, biopsies from human vitiligo subjects are collected from depigmented and NBUVB-treated skin. The skin cells (melanocytes and keratinocytes) are laser capture microdissected from hair follicle and epidermis and subjected to whole transcriptome RNA sequencing or qRT-PCR, followed by gene expression analysis. The current steps of this project involve the study of the functional phenotypes induced by the top signals and pathways modulated by NBUVB. For these goals, we manipulate melanocytes and keratinocytes in culture and ex vivo skin explants."

Epidemiology
Gates Center for Regenerative Medicine and Stem Cell Biology

Melanoma is caused by exposure to high levels of ultraviolet radiation (UVR). Susceptibility to melanoma is increased by genetic variation at a number of loci and by childhood exposures to UVR. My lab studies the skin-UVR interactions that impact on melanoma risk using both epidemiology and in vivo model systems. Our collaborative team is examining the gene-UVR interactions that give rise to melanocytic nevi in a longitudinal cohort of Colorado children that had annual data collected on nevus numbers and sizes, and on sun exposure behaviors. To date, we have identified key gene-UVR interactions that influence nevus development, and we have demonstrated that the number of sunburns and waterside vacations and the levels of chronic sun exposure experienced during childhood help to determine nevus counts. In parallel, we are studying the role of UVR in nevus and melanoma development using melanoma-prone mouse models.

Joseph Brzezinski , PhD
Assistant Professor
Opthalmolology

The retina is a highly complex neural tissue with many distinct cell types that are each required for normal vision. How do retinal stem cells decide which cellular identity to adopt during development. The Brzezinski lab studies the molecular mechanisms that underlie retinal cell fate choice decisions. Using this developmental knowledge, the lab also investigates how stem cells can be directly programmed into retinal neurons. Since the human retina is incapable of regenerating after injury or disease, new retinal neurons generated from stem cell sources have the potential to restore vision.

Freed

Curt Freed, MD
Division Head and Professor of Medicine

Research in my laboratory focus on novel treatments for Parkinson’s disease. We were the first in the United States to transplant human dopamine neurons into a Parkinson patient. We have developed a method for reprogramming human fibroblasts to induced pluripotent stem cells using non-integrating adenoviral vectors. We have shown that these iPS cells can be generated from people with Parkinson’s disease and can be differentiated to specific cell types such as dopamine neurons and other neural phenotypes. We are also working to stop the underlying process that causes Parkinson’s disease. We’ve discovered that the drug phenylbutyrate can turn on a protective gene called DJ-1 in all neurons and can thereby prevent Parkinson’s from developing a genetic mouse model of the disease. We are planning a double-blind trial to see if the drug can stop Parkinson’s in people.

KarinPayne

Karin Payne, PhD
Assistant Professor
Orthopedics

Research taking place in the Regenerative Orthopedics Laboratory focuses on harnessing the regenerative potential of stem cells for bone and articular cartilage tissue engineering. We are particularly interested in optimizing and controlling the ability of mesenchymal stem cells (MSCs) and induced pluripotent stem cells (iPSCs) to become bone and cartilage tissue by using different growth factors, scaffolds, and physicochemical cues. Current projects in the laboratory involve revitalizing bone allografts with stem cells to enhance bone formation, studying the effect of substrate stiffness on iPSC osteogenesis, growth plate tissue engineering, and investigating the effect of aging on the regenerative ability of stem cells.


Petrash

J. Mark Petrash, PhD
Professor and Vice-Chair of Research
Ophthalmology

Our lab works on ways to restore vision that has been lost due to genetics or disease. We are interested in finding ways to regenerate cells of the lens in patients with cataract, especially young people who need a clear vision for learning and working for many years to come. We also want to learn about the inherent ability of the lens to regenerate itself after surgery or trauma.


Nidia

Nidia Quillinan
Assistant Professor
Anesthesiology

We are pre-clinical basic science lab that investigates excitability and plasticity changes that contribute to neurological deficits. Our overarching goal is to identify therapeutic strategies to improve neuronal network function that will improve neurological outcome after brain injury. We use a multidisciplinary approach that includes in vivo animal models, electrophysiology, molecular analysis of gene and protein expression and virus-mediated gene manipulation. Current projects in the lab are aimed at investigating motor and cognitive deficits after cerebellar ischemia and changes in functional connectivity of the cerebellum with forebrain areas. We also study sex- and age-dependent mechanisms that contribute to neuronal injury and plasticity deficits in the hippocampus. We are particularly interested in how sex hormones contribute to injury and repair throughout the lifespan.


Reis_headshot_2018_101

Tania Reis, PhD​
Associate Professor
Molecular Biology Program

The Reis lab focus is on uncovering the genetic and neuronal basis of obesity. Obesity is a complex disorder with a strong genetic component. Body weight is influenced by a variety of tissues and organs throughout the body, not just those where fat is stored. Indeed, many obesity-predisposing genes are expressed primarily in the brain, but we understand few of the pathways by which the central nervous system maintains energy homeostasis. In the Reis lab we apply genetics, molecular biology and biochemistry techniques as well as behavioral analysis to identify and characterize neuronal and genetic factors controlling organismal fat storage using Drosophila melanogaster as a model system. Ongoing projects in the lab involve the role and mechanism of how RNA-binding proteins regulate organismal fat, and fat regulatory role of specific neuronal regions of the brain independent of metabolic behaviors (feeding and physical activity).

Holger Russ, PhD
Assistant Professor
Pediatrics

The Russ lab is investigating different aspects of autoimmune diabetes. Our interest ranges from identifying the molecular and cellular processes leading to disease development, to developing a treatment(s) for patients affected by diabetes. We employ state of the art pluripotent stem cell approaches, direct differentiation to generate functional cell types implicated in diabetes, genome engineering technology and organ co-cultures to generate novel model systems that provide unique biological insights in a strictly human context.

Dr. Shellman's research is focused on studying cancer and aging of pigment producing cells (melanocytes), and eventually to develop treatments for these health issues. This includes normal and abnormal regulation of melanocyte stem cell proliferation, differentiation and maintenance, inherited and acquired pigmentation disorders, as well as targeting melanoma stem cells as part of therapeutic development.

 


Headshot Tamburini (2)

Beth Tamburini, PhD
Assistant Professor
Medicine and Immunology

The focus of our lab is understanding how lymphatic vessels and the cells that comprise lymphatic vessels, lymphatic endothelial cells, regulate immune function and tissue homeostasis. As lymphatic endothelial cells are important both for immune cell trafficking and the drainage of interstitial fluid in every organ, these cells can have far reaching influences on a number of different systems. With that in mind we focus on how lymphatic endothelial cells react and program the immune system during immune insults such as viral and bacterial infections, immunization, chronic inflammation and cancer.


Terzian

Tamara Terzian, PhD
Assistant Professor
Dermatology
Gates Center for Regenerative Medicine and Stem Cell Biology

My laboratory is interested in the regulation of a key tumor suppressor, the transcription factor p53. p53 is mutated in over 50% of human cancers and has therefore been the subject of intensive basic and preclinical investigation. In the hope of improving cancer therapies that specifically target p53 mutations, we are investigating the role of different p53 mutations in driving tumorigenesis. For this, we are using novel combinations of extant mouse models of cancer, murine xenografts, and sophisticated tissue culture systems.


Torchia

Enrique Torchia, PhD
Assistant Professor
Dermatology
Gates Center for Regenerative Medicine and Stem Cell Biology

Our main focus is to understand how mitotic proteins such as Aurora Kinase A can control epithelial stem cell function in development and tissue homeostasis and are altered in proliferative diseases such as cancer. We utilize in vivo cancer models and tissue culture based systems to explore this question and ways of exploiting abnormal mitosis in disease as a therapeutic strategy.


Head Shot - Michael Verneris - small

Michael R. Verneris, MD
Professor of Pediatrics
Director of BMT and Cellular Therapy

The overarching goal of the Verneris laboratory is to create new targeted immune therapies to treat cancer in children and adults. Our laboratory is focused on using stem cells to create “off the shelf” living drugs to treat cancer and other diseases. To do this we use hematopoietic stem cells and induced pluripotent stem cells to understand how these cells give rise to natural killer (NK) cells and T cells. Thus, our research is in two broad areas:

Stem Cell Biology: We seek to understand how stem cells can be expanded and manipulated to differentiate into lymphocytes. We work with established embryonic and induced pluripotent stem cells, as well as hematopoietic stem cells derived from cord blood and bone marrow. Our studies are focused on stem cell biology and differentiation into the lymphocyte lineage (including NK cells, T cells, and innate lymphoid cells).

Lymphocyte Biology: We have focused on redirecting the immune system to cancer. Studies include the use and development of bi- and trispecific immune killer engagers (BiKes and TriKes) and chimeric antigen receptors (CARs). We have also discovered a how to differentiate stem cells to innate lymphoid cells and natural killer cells. We are using drugs and genetic screens to enhance this process and genetic manipulation to increase their activity and homing into solid tumors (sarcoma and brain tumors). The long term goal is to have an “off the shelf” living drug that can be used to mitigate graft vs. host disease, inflammatory bowel disease and cancer.


LWalker_Gates

Lori Walker, PhD
Assistant Professor
Medicine/Cardiology

My research efforts are focused on understanding the molecular mechanisms of heart failure, a complex, multifactorial syndrome characterized by both cardiac and systemic disturbances. It is clear that an insult – whether environmental or genetic – triggers a multitude of changes at the cellular level that ultimately result in organ level dysfunction. We use a number of models in order to address these changes on the cellular level, focusing on proteomic differences (translational and post-translational) in the dysfunctional heart. These models include a mouse myocardial infarction model, a genetic model that mimics heart disease in males and a genetic model that predominantly affects females, as studies show there is a disproportionate impact on women with regard to health consequences from heart failure. Additionally, collaborative efforts allow us to study a large animal (bovine) model of right heart dysfunction and other collaborations with the surgeons at the University of Colorado Hospital provide access to human heart samples – allowing elucidation of relevant pathways in human cardiac tissue. Together these models provide a platform for identifying the proteomic changes underlying cardiovascular disease and in describing the sexually divergent pathways cardiac maladaptation in women.
