Stem Cells for Immune System Regeneration to Fight Cancer

This proposal will define the biology of stem cell engineering to produce a cancer-fighting immune system. The immune system protects our body against most outside threats. However, it frequently fails to protect us from cancer. The T cell receptor (or TCR), a complex protein on the surface of an immune cell (or lymphocyte), allows to […]

GENE-MODIFIED HEMATOPOIETIC STEM/PROGENITOR CELL BASED THERAPY FOR HIV DISEASE

Embryonic-Derived Neural Stem Cells for Treatment of Motor Sequelae following Sub-cortical Stroke

A stroke kills brain cells by interrupting blood flow. The most common “ischemic stroke” is due to blockage in blood flow from a clot or narrowing in an artery. Brain cells deprived of oxygen can die within minutes. The loss of physical and mental functions after stroke is often permanent and includes loss of movement, […]

Stem Cell-Derived Astrocyte Precursor Transplants in Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS), a lethal disease lacking effective treatments, is characterized by the loss of upper and lower motor neurons. 5-10% of ALS is familial, but the majority of ALS cases are sporadic with unknown causes. The lifetime risk is approximately 1 in 2000. This corresponds to ~30,000 affected individuals in the United States […]

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, […]
