Novel Separation of Stem Cell Subpopulations
The inability to separate stem cells and their differentiated progeny accurately, easily, and rapidly undermines progress in the stem cell field. Traditional separation of living cells into subpopulations relies on techniques that utilize characteristic cell surface markers, but specific markers are severely limited or lacking altogether for many stem cell populations. Without ways to discriminate […]
Magnetic Particle Imaging: A Novel Ultra-sensitive Imaging Scanner for Tracking Stem Cells In Vivo
We aim to develop, test and validate a new, sensitive and affordable scanner for tracking the location of injected cells in humans and animals. This new scanning method, called Magnetic Particle Imaging, will ultimately be used to track the location and viability of stem cells within the human body. It could solve one of the […]
Development of Baculoviral Vectors for Gene Editing of Human Stem Cells
Stem cells are powerful undifferentiated cells that are able to both regenerate themselves and differentiate into different mature cell types, such as lung cells or liver cells. The ability to edit stem cell genomes is useful for both understanding stem cells at a fundamental level as well as for practical and therapeutic purposes, such as […]
A Novel SPECT Microscopy System for 3D Imaging of Single Stem Cells In Vivo
There are two main avenues of discovery open to medical scientists to find cures or alleviate suffering in people: 1) pharmaceuticals and 2) stem cells. Both of these branches of research use the emerging technological tools of imaging, genetic engineering and nanotechnology to explore new ways to manipulate molecular and cellular processes. In this project, […]
In Vivo Imaging for the Detection and Quantitation of Transplanted Stem/Progenitor Cells in Nonhuman Primates
Stem cells hold great potential for treating a variety of human diseases, but more information is needed on how they will function once administered to patients for regenerative medicine purposes. If imaging techniques can be developed that allow the monitoring of these transplanted stem and progenitor cells over time once injected into the body, this […]
RNA Analysis by Biosynthetic Tagging (RABT): a tool for the identification of cell type-specific RNAs
Advancing our understanding of stem cell biology often relies on answers to the following types of questions: What are the differences in gene expression between a stem cell and the “mature” cell (for example, a neuron or heart cell) made by the stem cell? Answers to such questions can lead to methods for directing stem […]
Regulation of Stem Cell Fate in Bioengineered Arrays of Hydrogel Microwells
Stem cell biology, since its inception 30 years ago, has been hindered by our limited ability to observe and direct the decisions of individual stem cells. In the case of adult tissue-specific stem cells, such as those from blood, muscle or pancreas, the numbers available for clinical use are extremely limited, as in tissue culture […]
Development of Suspension Adaptation, Scale-up cGMP Banking and Cell Characterization Technologies for hESC Lines
hESCs represent an important source of cell therapies in regenerative medicine and the study of early human development. A number of hESC-based therapies are nearing clinical trials. To bring these to clinical trials requires the scale-up production, or “banking”, of large numbers of the desired hESC cell. The current lack of large scale hESC culture […]
Optimization in the Identification, Selection and Induction of Maturation of Subtypes of Cardiomyocytes derived from Human Embryonic Stem Cells
Cardiovascular diseases remain the major cause of death in the western world. Stem and progenitor cell-derived cardiomyocytes (SPC-CMs) hold great promise for the myocardial repair. However, most of SPC-CMs displayed heterogeneous and immature electrophysiological phenotypes with substantial automaticity. Implanting these electrically immature and inhomogeneous CMs to the hearts would be arrhythmogenic and deleterious. Further optimization […]
Novel Tools and Technologies for Translational PET Imaging of Cell-based Therapies
One of the great promises of stem cell research is that doctors will find a way to isolate and modify patient’s stem cells so that they be reinjected into patients to treat their disease. Current examples include islet cell transplantation to treat diabetes, stem cells for treating heart failure, or engineered immune cells for treating […]
