Therapeutic/Technology: Therapeutic Approach
Stem Cell Gene Therapy for Sickle Cell Disease
Sickle cell disease (SCD), which results from an inherited mutation in the hemoglobin gene that causes red blood cells to “sickle” under conditions of low oxygen, occurs with a frequency of 1/500 African-Americans, and is also common in Hispanic-Americans, who comprise up to 5% of SCD patients in California. The median survival based on 1991 […]
HPSC based therapy for HIV disease using RNAi to CCR5.
RNA interference is a naturally occurring means to block the function of genes in our body. We propose that RNA interference can be used to block HIV-1 infection and its reproduction within the body. When RNA interference is introduced into a stem cell, its blocking activity will be present throughout the lifetime of the stem […]
Cell Therapy for Diabetes
Diabetes exacts a tremendous toll on patients, their families, and society in general. Autoimmune Type 1 diabetes, often called juvenile-onset diabetes, is caused by a person’s own immune system mistakenly destroying their insulin-producing cells in the pancreas, known as beta cells. When those beta cells are lost, the ability to produce insulin in response to […]
Autologous cardiac-derived cells for advanced ischemic cardiomyopathy
The adult human heart contains small numbers of cardiac stem cells that are able to partially repair the heart following a heart attack or throughout the course of progressive heart failure. We have developed a method to isolate these cells and grow them to large numbers in the lab. Isolation begins with a minimally-invasive biopsy […]
Stem Cell-Mediated Oncocidal Gene Therapy of Glioblastoma (GBM)
Brain tumors (BTs) are incurable, whether they start in the brain or spread there from other sites. Despite advances in surgical, radiation, pharmacologic, and gene therapies, survival with a BT remains dismal. Current therapies are limited by their inability to reach widely disseminated tumor cells that become dispersed within normal brain structures. Interestingly, the therapeutic […]
Stem Cell-mediated Therapy for High-grade Glioma: Toward Phase I-II Clinical Trials
Despite aggressive multimodal therapy and advances in imaging, surgical and radiation techniques, malignant brain tumors (high-grade gliomas) remain incurable, with survival often measured in months. Treatment failure is largely attributable to the diffuse and invasive nature of these brain tumor cells, ineffective delivery of chemotherapeutic agents to tumor sites, and toxic side-effects to the body, […]
iPS Cell-Based Treatment of Dominant Dystrophic Epidermolysis Bullosa
Genetic skin diseases constitute a diverse group of several hundred diseases that affect up to 2% of the population and include common disease such as psoriasis, atopic dermatitis, and wound healing. Patients with one genetic disease, dystrophic Epidermolysis bullosa (EB), lack a normal collagen VII (COL7A1) gene and suffer from debilitating blistering and scarring that […]
Development of Therapeutic Antibodies Targeting Human Acute Myeloid Leukemia Stem Cells
Acute myeloid leukemia (AML) is a cancer of the blood and bone marrow that is rapidly fatal within months if untreated. Even with aggressive treatment, including chemotherapy and bone marrow transplantation, five-year overall survival rates range between 30-40%. Evidence indicates that not all cells in this cancer are the same, and that there is a […]
Therapeutic Opportunities To Target Tumor Initiating Cells in Solid Tumors
Cancer is a major cause of human death worldwide. The vast majority of cancer patients suffer from solid tumors whose growth destroys vital organs. We propose to develop novel therapeutic drugs that target solid tumors affecting the brain, colon and ovaries. These cancers account for a significant proportion of currently intractable solid malignancies. Scientists have […]
ZINC FINGER NUCLEASE-BASED STEM CELL THERAPY FOR AIDS
Some years ago it was discovered that patients homozygous for a natural mutation (the Δ32 mutation) in the CCR5 gene are generally resistant to HIV infection by blocking virus entry to a cell. Building on this observation, a study published in 2009 reported a potential “cure” in an AIDS patient with leukemia after receiving a […]
