Human Stem Cell Use: Embryonic Stem Cell
Development of a scalable, practical, and transferable GMP-compliant suspension culture-based differentiation process for cardiomyocyte production from human embryonic stem cells.
As ongoing CIRM-funded development of regenerative medicine (RM) progresses, the demand for increasing numbers of pluripotent stem cells and their differentiated derivatives has also increased. We have established a scalable suspension culture system for the production of large quantities of hESC for banking and to seed production of a number of regenerative medicine cell types, […]
Engineered Biomaterials for Scalable Manufacturing and High Viability Implantation of hPSC-Derived Cells to Treat Neurodegenerative Disease
Cell replacement therapies (CRTs) have considerable promise for addressing unmet medical needs, including incurable neurodegerative diseases. However, several bottlenecks hinder CRTs, especially the needs for improved cell manufacturing processes and enhanced cell survival and integration after implantation. Engineering synthetic biomaterials that present biological signals to support cell expansion, differentiation, survival, and/or integration may help overcome […]
A Chromatin Context Tool for Predicting iPS Lineage Predisposition and Tissue Graftability
Induced pluripotent stem (iPS) cells are cells derived from skin that closely resemble embryonic stem (ES) cells and can be coaxed into many different types of cells such as nerve cells, heart cells, liver cells, and also back to skin cells. One major bottleneck in the field is our ability to coax the cells into […]
A suite of engineered human pluripotent stem cell lines to facilitate the generation of hematopoietic stem cells
Our goal is to develop tools that address major bottlenecks that have prevented the generation of blood forming stem cells in culture for therapeutic use. To help overcome these bottlenecks, we will generate a suite of human embryonic stem cell reporter lines that can be used to monitor key milestones in blood stem cell development. […]
Identification and isolation of transplantable human hematopoietic stem cells from pluripotent cell lines; two steps from primitive hematopoiesis to transplantable definitive cells, and non-toxic conditioning of hosts for hematopoeitic stem cell transp…
A goal of stem-cell therapy is to transplant into a patient “tissue-specific” stem cells, which can regenerate a particular type of healthy tissue (e.g., heart or blood cells). A major obstacle to this goal is obtaining tissue-specific stem cells that (1) are available in sufficient numbers; and (2) will not be rejected by the recipient. […]
A small molecule tool for reducing the malignant potential in reprogramming human iPSCs and ESCs
This research project aims to solve a key bottleneck in the use of differentiated human embryonic stem cells and induced pluripotent stem cells for the regeneration and replacement of diseased or damaged tissues. This bottleneck is the potential of unintended transplants containing failed-to-differentiate stem cells developing into benign growths called teratomas, or worse, malignant teratocarcinomas. […]
User-friendly predictive molecular diagnostic assays for quality control of stem cell derivatives for transplantation and drug discovery
Three years ago, with help from CIRM funding, we developed an assay. This is a genomics-base diagnostic assay, similar to those now used for diagnosing cancers; but in our case, it is designed to analyze human ES and iPS cells. The assay is very simple to use; researchers use microarrays to profile the genes that […]
Development of a Relevant Pre-Clinical Animal Model as a Tool to Evaluate Human Stem Cell-Derived Replacement Therapies for Motor Neuron Injuries and Degenerative Diseases
Motor neurons degenerate and die as a consequence of many conditions, including trauma to the spinal cord and its nerve roots and degenerative diseases such as amyotrophic lateral sclerosis and spinal muscular atrophy. Paralysis and in many cases death may result from a loss of motor neurons. No effective treatments are available for these patients. […]
A Phase I/IIa Dose Escalation Safety Study of AST-OPC1 in Patients with Cervical Sensorimotor Complete Spinal Cord Injury
The proposed project is designed to assess the safety and preliminary activity of escalating doses of human embryonic stem cell derived oligodendrocyte progenitor cells (OPCs) for the treatment of spinal cord injury. OPCs have two important functions: they produce factors which stimulate the survival and growth of nerve cells after injury, and they mature in […]
Non-invasive live imaging of stem cell signature metabolic states
Stem cells in tissues exhibit unique metabolic states that could distinguish them from other more specialized cells. Using a new type of microscopy we can image the metabolic states of cells in living tissues and, therefore, attempt to identify stem cell populations. Because stem cells can give rise to tumors that are metabolically very different […]
