Injectable Hydrogels for the Delivery, Maturation, and Engraftment of Clinically Relevant Numbers of Human Induced Pluripotent Stem Cell-Derived Neural Progenitors to the Central Nervous System
One critical bottleneck in the translation of regenerative medicine into the clinic is the efficient delivery and engraftment of transplanted cells. While direct injection is the least invasive method for cell delivery, it commonly results in the survival of only 5-20% of cells. Studies suggest that delivery within a carrier gel may enhance cell viability, […]
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 […]
Small molecule tools and scale-up technologies to expand human umbilical cord blood stem and progenitor cells for clinical and research use
Tens of thousands of patients need bone marrow transplants (BMT) every year, some for bone marrow (BM) cancers and some for inherited diseases such as sickle cell anemia and thalassemia, but many lack a BM donor. African Americans, Asian Americans, and people of Hispanic descent are more likely than others to lack a stem cell […]
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. […]
Development of a clinical-grade extracorporeal liver support system using human induced pluripotent stem cell-derived hepatic cells
Liver failure is the fourth leading cause of adult death in California. Because liver cells can regenerate, some patients with liver failure could be saved without having to undergo organ transplantation if their liver function could be supported temporarily. Here, we propose to develop a device to support these patients called the “extracorporeal liver support […]
Engineering Defined and Scaleable Systems for Dopaminergic Neuron Differentiation of hPSCs
Human pluripotent stem cells (hPSC) have the capacity to differentiate into every cell in the adult body, and they are thus a highly promising source of differentiated cells for the investigation and treatment of numerous human diseases. For example, neurodegenerative disorders are an increasing healthcare problem that affect the lives of millions of Americans, and […]
Development of a Hydrogel Matrix for Stem Cell Growth and Neural Repair after Stroke
Stroke is the leading cause of adult disability. Most patients survive their initial stroke, but do not recover fully. Because of incomplete recovery, up to 1/3 of stroke patients are taken from independence to a nursing home or assisted living environment, and most are left with some disability in strength or control of the arms […]
