Robertson Parkman
Other Teaching Staff-Hourly, Pediatrics - Stem Cell Transplantation
BioMy principal research interests have been the assessment of the immunological consequences of hematopoietic stem cell transplantation including both acute and chronic graft versus host disease and immune reconstitution and the use of hematopoietic stem cell transplantation to treat genetic diseases. My laboratory was the first to suggest that chronic graft versus host disease was an autoimmune disease directed at histocompatibility antigens shared by donors and recipients. The observation leaded to the assessment of the role of thymic dysfunction in the pathogenesis of chronic graft versus host disease. As a pediatric immunologist I have investigated the role of hematopoietic stem cell transplantation initially in the treatment of primary immune deficiency diseases and later the treatment of metabolic diseases, which lead to my involvement in the early gene transfer clinical trials.

Jane Parnes
Professor of Medicine, Emerita
Current Research and Scholarly InterestsThe lab is studying the mechanisms controlling B cell responsiveness and the balance between tolerance and autoimmunity. B cells deficient in CD72 are hyperresponsive to stimulation through the B cell receptor. We are examining the alterations in B cell signaling in these B cells and the mechanisms by which CD72 deficiency partially abrogates anergic tolerance. We hope to learn how deficiency in CD72 leads to spontaneous autoimmunity and increased susceptibility to induced autoimmune disease.

The research team employs a multidisciplinary approach involving genetics, molecular and developmental neurobiology, animal models and neural cells differentiated from patient-derived induced pluripotent stem (iPS) cells. In particular, the lab is using a powerful 3D human brain-region specific organoid system developed at Stanford (Nature Methods, 2015; Nature Protocols, 2018) to ask questions about brain injury during development.

Sergiu P. Pasca
Kenneth T. Norris, Jr. Professor of Psychiatry and Behavioral Sciences and Bonnie Uytengsu and Family Director of the Stanford Brain Organogenesis Program
Current Research and Scholarly InterestsA critical challenge in understanding the intricate programs underlying development, assembly and dysfunction of the human brain is the lack of direct access to intact, functioning human brain tissue for detailed investigation by imaging, recording, and stimulation.
To address this, we are developing bottom-up approaches to generate and assemble, from multi-cellular components, human neural circuits in vitro and in vivo.
We introduced the use of instructive signals for deriving from human pluripotent stem cells self-organizing 3D cellular structures named brain region-specific spheroids/organoids. We demonstrated that these cultures, such as the ones resembling the cerebral cortex, can be reliably derived across many lines and experiments, contain synaptically connected neurons and non-reactive astrocytes, and can be used to gain mechanistic insights into genetic and environmental brain disorders. Moreover, when maintained as long-term cultures, they recapitulate an intrinsic program of maturation that progresses towards postnatal stages.
We also pioneered a modular system to integrate 3D brain region-specific organoids and study human neuronal migration and neural circuit formation in functional preparations that we named assembloids. We have actively applied these models in combination with studies in long-term ex vivo brain preparations to acquire a deeper understanding of human physiology, evolution and disease mechanisms.
We have carved a unique research program that combines rigorous in vivo and in vitro neuroscience, stem cell and molecular biology approaches to construct and deconstruct previously inaccessible stages of human brain development and function in health and disease.
We believe science is a community effort, and accordingly, we have been advancing the field by broadly and openly sharing our technologies with numerous laboratories around the world and organizing the primary research conference and the training courses in the area of cellular models of the human brain. -

Anisha I Patel
Professor of Pediatrics (General Pediatrics) and, by courtesy, of Epidemiology and Population Health
Current Research and Scholarly InterestsDr. Patel is a physician-scientist with a focus on community-engaged research (CEnR). She works to translate evidence to impact policies that can benefit children facing inequities due to their racial/ethnic background, poverty, and/or geography.
She leads the independently-funded research program, Partnerships for Research in Child Health, which collaborates with community partners to co-develop, implement, and evaluate innovative interventions aimed at preventing obesity and cardiometabolic diseases in low-income, minoritized populations. Over the past 10 years, Dr. Patel has led numerous studies to encourage healthy beverage intake among children and adolescents. These studies include analyses of large national data sets, conduct of randomized controlled trials in schools, child care, and community settings to examine how interventions to increase children’s intake of water instead of sugar-sweetened beverages impact child health, and the evaluation of policy efforts to improve the healthfulness of beverages offered in schools and community settings.
Long before the Flint water crisis, Dr. Patel was working with partners to address nitrate and arsenic contamination in drinking water supplies in California’s San Joaquin Valley, a rural region home to many low-income Latinx farm-working families. She secured funding from the National Institute of Child Health and Human Development to collaborate with researchers, nonprofits, water utilities, families, and advocates to develop innovative solutions to drinking water contamination in the region, helping to lead to the Agua4All program. The Agua4All initiative increased access to safe drinking water by installing filtered water stations in schools and community sites. The program’s success led to its national expansion and informed a $16.3 million-dollar water in schools grant program as well as California legislation to improve safe water access in public schools. Dr. Patel’s work with collaborators and communities was recognized by First Lady Michelle Obama’s Drink Up campaign and featured in Stanford Medicine’s award-winning magazine.
As an expert in CEnR, Dr. Patel leads initiatives at Stanford. She is Director of the Office of Community-Engaged Research at Stanford's Maternal and Child Health Research Institute. In this role, she is helping to lead several initiatives, including expanding grant funding for CEnR and implementing capacity-building training programs for both community partners and the Stanford community. She also serves as Associate Dean of Research in Stanford’s School of Medicine, where she works to enhance community engagement across the university. Dr. Patel is a Co-Investigator on Stanford’s Clinical Translational Sciences Award. She also helps lead mentoring of fellows and junior faculty in CEnR.
