Prospective isolation of hESC-derived hematopoietic and cardiomyocyte stem cells
The capacity of human embryonic stem cells (hESCs) to perpetuate themselves indefinitely in culture and to differentiate to all cell types of the body has lead to numerous studies that aim to isolate therapeutically relevant cells for the benefit of patients, and also to study how genetic diseases develop. However, hESCs can cause tumors called […]
Improving microenvironments to promote hematopoietic stem cell development from human embryonic stem cells
Hematopoietic stem cells (HSC) have been used successfully to cure various life-threatening blood diseases. Yet, matching HSCs are not available for every patient. Human embryonic stem cells (hESC) may provide an unlimited source of HSCs for therapeutic use. However, hESC derived hematopoietic cells do not develop properly in those culture conditions that are currently used, […]
Generation of long-term cultures of human hematopoietic multipotent progenitors from embryonic stem cells
For many therapeutic reasons it is important to have available large numbers of blood cells. However, it is difficult to generate large numbers of specialized blood cells that have the ability to neutralize autoimmunity and response to tumor cell growth. In this study we would develop a technique that would allow the production of large […]
Self-renewal and senescence in iPS cells derived from patients with a stem cell disease
The discovery of induced pluripotent stem (iPS) cell technology promises to revolutionize our understanding of human disease and to allow the development of new cellular therapies for regenerative medicine applications. The ability to reprogram a patient’s fibroblasts to iPS cells creates the opportunity to expand human cells with a specific genetic defect and to study […]
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 […]
Molecular Characterization and Functional Exploration of Hemogenic Endothelium
Hematopoietic cells are responsible for generating all cell types present in the blood and therefore critical for the provision of oxygen and nutrients to all the tissues in the body. Blood cells are also required for defense against microorganisms and even for the recognition and elimination of tumor cells. Because blood cells have a relatively […]
Autologous BCMA CAR-T Cells for the Treatment of Relapsed Refractory Light Chain Amyloidosis
Determining how age-specific heterogeneity of human hematopoietic stem cells and megakaryocyte progenitors contribute to thrombotic disease upon aging
Research Objective Our research will determine how aging of human blood stem cells leads to dramatic increases in disorders of platelets, cells that normally prevent bleeding but form harmful clots when dysregulated. Impact Our findings have the potential to inform prevention and mitigation strategies of bleeding and clotting disorders that contribute to significant morbidity and […]
Phase 2 Study of Hematopoietic Stem Cell Gene Transfer Inducing Fetal Hemoglobin in Sickle Cell Disease
Therapeutic Candidate or Device Autologous CD34+ cells transduced ex vivo with the BCH_BB694 LCR(-HS4) bGp D12shmiR lentiviral vector Indication Sickle cell disease with severe phenotype. Therapeutic Mechanism Silencing of beta-sickle globin and induction of anti-sickling fetal hemoglobin Unmet Medical Need Sickle cell is a severe disease with protean manifestations. The only curative therapy is an […]
Transplantation of CRISPR-CAS9 Corrected Hematopoietic Stem Cells (CRISPR_SCD001) in Patients with Severe Sickle Cell Disease
Therapeutic Candidate or Device CRISPR corrected blood stem cells are manufactured from persons with severe sickle cell disease and returned by transplant to the same person Indication Persons with sickle cell disease (adults and adolescents) with repeated, severe painful and lung events are eligible for the clinical trial Therapeutic Mechanism Blood stem cells are harvested […]
