A new precision medicine based iPSC-derived model to study personalized intestinal fibrosis treatments in pediatric patients with Crohn’s disease
Research Objective We propose to discover a tool that will utilize patient specific iPSC-derived human mini-guts to identify personalized antifibrotic treatments in pediatric Crohn’s disease patients Impact The major bottleneck in intestinal fibrosis research is the difficulty in obtaining patient-specific biologically relevant cells for in vitro modeling. This iPSC-derived tool would overcome it. Major Proposed […]
AAV-dCas9 Epigenetic Editing for CDKL5 Deficiency Disorder
Research Objective We propose a gene therapy for the treatment of a severe infantile epilepsy called CDKL5 Deficiency Disorder using CRISPR-mediated epigenetic editing Impact A transformative treatment for females affected by CDKL5 Deficiency Disorder in addition a platform for the approximately 38 other X-linked intellectual disabilities that predominately affect females Major Proposed Activities Validation of […]
iPSC-derived smooth muscle cell progenitor conditioned medium for treatment of pelvic organ prolapse
Research Objective Conditioned media from human iPSC-derived smooth muscle cell progenitors. This media exerts paracrine effect to restore damaged vaginal wall in patients with pelvic organ prolapse. Impact Pelvic organ prolapse (POP) is characterized by the downward movement of the vagina and/or uterus through the vaginal opening. It is treated with surgery. The candidate is […]
iPSC Extracellular Vesicles for Diabetes Therapy
Research Objective We will derive extracellular vesicles (EVs) from induced pluripotent stem cells (iPSCs), characterize the content and immunomodulatory activity of EVs, and deliver iPSC-EVs to treat Type-1 diabetes. Impact Type 1 diabetes (T1D) is an autoimmune disease and there is no therapy to preserve islet cells. Accomplishment of this project will generate a new […]
RNA-directed therapy for Huntington’s disease
Research Objective We develop a novel adeno-associated viral (AAV) vector-delivered RNA-targeting therapeutic for elimination of toxic RNA causative of Huntington’s disease. Impact There are no disease-modifying therapies for Huntington’s disease. Our therapeutic, if successful, will be a first-in-class treatment for this invariably fatal neurodegenerative disorder. Major Proposed Activities In vitro studies of the RNA-targeting system […]
Transplantation of genetically corrected iPSC-microglia for the treatment of Sanfilippo Syndrome (MPSIIIA)
Research Objective This research will discover whether transplantation of stem cell-derived microglia can be used to treat Sanfilippo syndrome, a devastating and currently untreatable childhood neurological disease. Impact If successful, this research will identify a promising new therapeutic approach for Sanfilippo Syndrome and provide the first evidence that stem cell derived microglia could be used […]
Improving the efficacy and tolerability of clinically validated remyelination-inducing molecules using developable combinations of approved drugs
Research Objective The candidate is a fixed dose binary small molecule drug combination, consisting of two agents that act synergistically on a multipotent stem cell population in the CNS to stimulate remyelination. Impact The proposed studies will address bottleneck issues related to the effect size and tolerability of clinically validated remyelination drug classes. Major Proposed […]
Injectable, autologous iPSC-based therapy for spinal cord injury
Research Objective We propose to develop and validate a therapy for spinal cord injuries in which human stem cell-derived neural cells is injected into the injured spinal cord using an injectable gel. Impact Our study will address the critical need for an SCI treatment that significantly improves the neurological recovery and hence quality of life […]
Optimization of a gene therapy for inherited erythromelalgia in iPSC-derived neurons
Research Objective The goal of this grant is to develop a gene therapy for a rare painful disorder, Inherited Erythromelalgia (IEM). Impact There are currently no FDA approved drugs for IEM, which is caused by a gain-of-function mutation in a sodium channel, Nav1.7. We propose epigenetic repression of Nav1.7 to provide a cure for IEM. […]
A novel hybrid CRISPR tool for gene network perturbation and hiPSC engineering
Research Objective A CRISPR-based tool for simultaneous up- and downregulation of many (~5-20) genes, and a computational tool using scRNA-seq data to predict which genes to perturb for efficacious cell-type conversion. Impact A critical bottleneck to the creation of specific cell types from stem cells (and related therapies) is our current inability to make cells […]
