Human Stem Cell Use: Adult or Tissue Stem Cell
Genome Editing to Correct Cystic Fibrosis Mutations in Airway Stem Cells
Research Objective Gene corrected autologous airway epithelial stem cells from patients with cystic fibrosis to be used as cell and gene based therapy for chronic sinus disease Impact The proposed studies would provide an innovative, readily applied primary stem cell based approach with gene correction to treat chronic sinusitis in CF, a debilitating airway disease. […]
Protein tyrosine phosphatase – sigma inhibitors for hematopoietic regeneration
Research Objective We propose to develop a lead small molecule inhibitor of PTPσ, a receptor expressed by human blood stem cells, for the purpose of promoting human hematopoietic regeneration. Impact Systemic administration of a PTPσ inhibitor can accelerate hematologic recovery in thousands of patients who have received myelosuppressive chemo- or radiotherapy. Major Proposed Activities Generate […]
Preclinical development of human hepatocyte progenitor cells for cell therapy
Research Objective Determine if human hepatocyte progenitor cells, which exist in the normal adult liver, can be maintained and expanded in vitro while maintaining in vivo regenerative capacity. Impact Cell transplantation therapy can be an effective alternative treatment for severe liver diseases to liver transplantation, which is severely limited by the lack of available donor […]
GENE EDITING FOR FOXP3 IN HUMAN HSC
Research Objective CRISPR/Cas9 mediated FOXP3 gene editing in patient-derived hematopoietic stem cells as a cure for IPEX syndrome Impact FOXP3 mutation in IPEX syndrome leads to immune system dysregulation. Allogeneic HSCT, the only available treatment, has very poor outcomes including GvHD and low immune reconstitution. Major Proposed Activities Demonstrate specificity of targeted insertion of FOXP3 […]
Immunotherapy for HIV infection using engineered hematopoietic stem/progenitor cells
Research Objective The therapeutic candidate proposed here is hematopoietic stem/progenitor cells engineered to encode for HIV-specific T cell receptors. Impact The success of the proposed studies will test the efficacy of an approach to provide long-lasting functional cure for HIV infection, obviating the need for anti-retroviral therapy. Major Proposed Activities Test if engineered hematopoietic stem/progenitor […]
MSC delivery of an artificial transcription factor to the brain as a treatment for Angelman Syndrome
Research Objective Mesenchymal stem cells will be used to deliver an artificial transcription factor to neurons in the brain to treat a genetic disease. Impact It could lead directly to a treatment for Angelman Syndrome, but the approach could be used to alter gene expression in almost any brain disorder. It could overcome the brain […]
Gingival mesenchymal stem cells as a novel treatment modality for periodontal tissue regeneration
Research Objective To develop a novel regenerative and adhesive hydrogel encapsulating patient's' gingival stem cell which can potentially be used as an adhesive dental hydrogel for periodontal tissue regeneration. Impact Upon successful completion, this project will introduce a promising treatment approach for maxillofacial defects presenting an innovative treatment modality for periodontal tissue regeneration. Major Proposed […]
Bone Marrow Targeting of Hematopoietic Stem Cells Engineered to Overexpress 25-OH-VD3 1-α-hydroxylase for Acute Myeloid Leukemia Therapy
Research Objective We propose a new approach to differentiation therapy for acute myeloid leukemia by producing local level of high-dose vitamin D in bone marrow via cell therapy with engineered hematopoietic stem cells Impact If proven successful, the proposed research can serve as a major breakthrough in the treatment of multiple subtypes of AML and […]
Optimizing self-renewal signaling kinetics to stabilize ex vivo hematopoietic stem cell expansion
Research Objective We aim to develop conditions for stable expansion of blood stem cells outside of the body Impact Blood stem cells are a rare but necessary cell type for curative bone marrow transplantation and related gene therapies. Stable blood stem cell expansion will increase therapy availability and success Major Proposed Activities Validate a fully […]
Development of treatments to improve healing of ischemic wounds
Research Objective We aim to develop an angiogenic proteoglycan mimic that will protect tissue from rapid degradation, and in conjunction with EPCs promote angiogenesis in order to accelerate ischemic wound healing. Impact As a treatment, LXW7-DS-SILY combined with a collagen scaffold and EPCs will accelerate healing of ischemic diabetic foot ulcers and reduce limb amputation […]
