Human Stem Cell Use: Adult or Tissue Stem Cell

Stem cell-based carriers for RCR vector delivery to glioblastoma

Modified viruses can be used to infect tumor cells and alter the tumor cell to make anti-tumor proteins. Most researchers use virus that can infect and modify the tumor cell it enters, but can not make more of itself to infect additional cells surrounding the original infected cell. This type of virus is called replication-incompetent […]

Human retinal progenitor cells as candidate therapy for retinitis pigmentosa

The targeted disease is retinitis pigmentosa (RP), is a severe form of blindness that runs in families. This disease is not overly common, yet represents an attainable near term target for stem cell therapy for a number of reasons: 1) RP destroys the light detecting cells of the retina but generally leaves the rest of […]

Harnessing native fat-residing stem cells for bone regeneration

Like most tissues of the body, bone possesses a natural regenerative system aimed at restoring cells and tissues lost to natural cell aging, disease or injury. These natural regenerative systems are complex combinations of cell growth factors and support structures that guide and control the development of specialized bone stem cells. However, the regeneration process […]

Cartilage Regeneration by the Chondrogenic Small Molecule PRO1 during Osteoarthritis

The ability to direct the differentiation of resident mesenchymal stem cells (MSCs) towards the cartilage lineage offers considerable promise for the regeneration of articular cartilage after traumatic joint injury or age-related osteoarthritis (OA). MSCs can be stimulated in vitro to form new functional cartilage. In the OA-affected joint, the repair is insufficient, leaving a damaged […]

Niche-Focused Research: Discovery & Development of Hematopoietic Regenerative Factors

Bone marrow and peripheral blood transplantation utilizing blood stem cells can provide curative treatment for patients with cancers and non-cancerous diseases of the blood and immune systems. Such treatments can be curative because the stem cells contained within the bone marrow or peripheral blood of healthy donors are capable of replacing the entirety of the […]

Molecular mechanisms of neural stem cell differentiation in the developing brain

One of the most exciting possibilities in stem cell biology is the potential to replace damaged or diseased neural tissues affected by neurodegenerative disorders. Stem-cell-derived neurons provide a potentially limitless supply of replacement cells to repair damaged or diseased neurons. Typically, only one or a very few types of neurons are affected in most neurodegenerative […]

Combinatorial Chemistry Approaches to Develop LIgands against Leukemia Stem Cells

Various cells and organs in the human body originate from a small group of primitive cells called stem cells. Human cancer cells were also recently found to arise from a group of special stem cells, called cancer stem cells (CSCs). At present, cancer that has spread throughout the body (metastasized) is difficult to treat, and […]

Mechanisms of Hematopoietic stem cell Specification and Self-Renewal

During an individual’s lifetime, blood-forming cells in the bone marrow called hematopoietic stem cells (HSCs) supply all the red and white blood cells needed to sustain life. These blood stem cells are unique because they can make an identical copy of themselves (self-renew). Disorders of the blood system can be terminal, but such diseases may […]

Molecular mechanisms involved in adult neural stem cell maintenance

The adult brain contains a pool of stem cells, termed adult neural stem cells, that could be used for regenerative purposes in diseases that affect the nervous system. The goal of this proposal is to understand the mechanisms that promote the maintenance of adult neural stem cells as an organism ages. Understanding the factors that […]

A Novel Engineered Niche to Explore the Vasculogenic Potential of Embryonic Stem Cells

Cardiovascular diseases account for an estimated $330 billion in health care costs each year, afflict 61.8 million Americans, and will account for more than 1.5 million deaths in the U.S. this year alone. A number of these diseases are characterized by either insufficient blood vessel growth or damage to the existing vessels, resulting in inadequate […]
