hPSC-derived enteric ganglioids for cell therapy in gastrointestinal motility disorders
Research Objective The proposed aims will enable the generation, purification and characterization of enteric neurons from diverse hiPSCs and assessment of their efficacy for cell therapy in GI motility disorders. Impact This proposal addresses a significant unmet clinical need for a cell therapy approach for gastrointestinal motility disorders such as Hirschsprung disease, achalasia and gastroparesis. […]
Defining the source of dysfunction in monogenic Intellectual Disability Syndrome neurons
Research Objective This study will use pluripotent stem cells derived from patients to determine why Intellectual Disabilities caused by mutations in chromatin regulatory proteins leads to neuronal defects. Impact Our study of intellectual disability syndromes will determine links between mutations and neuronal dysfunction Major Proposed Activities Our study of intellectual disability syndromes will determine links […]
An interactive data resource for hypothesis testing in stem cell single-cell gene expression and validation of the results with brain organoids
Research Objective We are building a "virtual molecular microscope" where anyone can quickly visualize a very recent, high-throughput molecular assay, single-cell RNA-seq and spatial gene expression studies Impact Currently, a lot of data has been published, hundreds of datasets on the cerebral cortex alone, but it takes hours to convert the datasets and look at […]
Mapping the spatial and temporal responses of hESC-derived microglia to repeat mild closed head injury to identify therapeutic targets and mechanisms
Research Objective We will generate an RNA activation map of human stem cell derived microglia activation states following brain injury to then test a new gene-edited microglia peptide delivery mechanism. Impact Bottlenecks with the time and sex-dependent human microglia responses to repeat mild closed head injury and questions surrounding the delivery and efficacy of a […]
Role of ataxin-3 polyadenylation site selection in ALS neuron toxicity and disease pathogenesis
Research Objective Here we will study the role of ataxin-3 alternative polyadenylation in the pathogenesis of ALS, and test if ASOs can reduce distal polyadenylation of ataxin-3 to rescue ALS disease phenotypes Impact Our goal is to determine if ataxin-3 genetic dysregulation is a target for the development of therapies to treat ALS (Lou Gehrig's […]
Identifying roadblocks to neural stem cell transplantation into human tissues.
Research Objective We will generate a comprehensive map of human neural stem cell differentiation profiles that will serve as a reference for enhancing neural stem cell-based therapies. Impact Our project will develop improved protocols for human neural stem cells differentiation, enhancing the fidelity, safety and robustness of future cell therapies. Major Proposed Activities Establish quantitative […]
Functional genomics to study cellular convergence across ASD risk genes in neurodevelopment
Research Objective Our objective is to enable scalable genetic screening to study how neurogenesis is impacted by risk genes implicated in human psychiatric disorders. Impact We will develop and apply state-of-the-art genomic analysis to seek mechanisms and disease modifying solutions. Major Proposed Activities Identifying and validating efficient gRNA for gene editing Identify risk gene effects […]
Harnessing vascular stem cells to grow and protect the human brain
Research Objective The origins of brain vascular mural cells are unknown. This proposal will identify mural stem cells in the developing human and mouse brain and determine their impact on blood brain barrier formation. Impact Brain vascular diseases can have profound impacts on long-term neurological function. This proposal will map the stages of mural stem […]
Understanding Chemotherapy-Induced Peripheral Neuropathy Mechanisms using CRISPRi and Chemical Screens in Human iPSC-Derived Sensory Neurons
Research Objective The research objectives are to identify causal genes for chemotherapy-induced mitochondrial toxicity and neurodegeneration in sensory neurons and drugs that target this toxicity. Impact These studies will open the possibility for genetic or drug targeting to prevent and treat drug-induced peripheral neuropathies and possibly neuropathies caused by disease or inherited. Major Proposed Activities […]
Developing a Human Model of Sporadic ALS Using Machine Learning and Robotic Microscopy
Research Objective We will develop the first human stem cell model of sporadic ALS (sALS) to identify disease mechanisms in the most common form of ALS and to discover drugs to treat the vast majority of ALS patients. Impact Failure of drugs to treat sALS may be due to the use of models of familial […]
