Human Stem Cell Use: Adult or Tissue Stem Cell


Enhancing hair cell regeneration in mouse and human inner ear

Hearing loss (HL) is a permanent sensory disorder affecting over 278 million people worldwide. In the US and California, 20% of individuals suffer from this sensory deficit. Those affected range from newborns (2 per 1000), to children aged 3-17 (5 per 1000), to adults including the elderly (~33% in aged 65-74 and ~50% >85 years […]

Stem cell therapy for inflammatory bowel disease

One of the most promising approaches that physicians foresee for treating human disease is regenerative medicine. A major aim in this field is to restore function by repairing damaged organs. Inflammatory bowel disease (IBD) is a chronic disease characterized by intermittent episodes of intestinal inflammation and disruption of the intestinal epithelial barrier. It causes significant […]

White matter neuroregeneration after chemotherapy: stem cell therapy for “chemobrain”

Chemotherapy for cancer is often life saving, but it also causes a debilitating syndrome of impaired cognition characterized by deficits in attention, concentration, information processing speed, multitasking and memory. As a result, many cancer survivors find themselves unable to return to work or function in their lives as they had before their cancer therapy. These […]

Characterization of Human Skeletal Muscle Stem Cells for Clinical Application

Skeletal muscle makes up 40% of our bodies, dictates our form, is responsible for our ability to move, express ourselves, eat, breath and to look around. Restoration or preservation of the body’s normal form and function is the central goal of regenerative medicine and the central focus of my clinical specialty of plastic and reconstructive […]

Tunable hydrogels for therapeutic delivery of multipotent stem cells.

Rationale: Skin ulcers represent the largest economic burden of all skin diseases. Human adult stem cell therapies for the treatment of chronic wounds have shown considerable promise. However, a delivery system is needed before they can be used clinically. Hydrogels have emerged as a promising vehicle for stem cell delivery because their 3-D structure and […]

The generation and expansion of tissue-engineered small intestine from human stem/ progenitor cells: a preclinical study of functional translation

This proposal aims to complete the preclinical steps to develop tissue-engineered intestine (TESI) as a functional replacement of the small intestine to treat short bowel syndrome (SBS). Common birth conditions especially those associated with prematurity result in SBS wherein 50-75% of the small intestine is gone. SBS children cannot get adequate nutrition and supportive medical […]

Regulation of Epidermal Self-Renewal and Differentiation by Histone and DNA Demethylases.

Tissue specific stem and progenitor cells exist to replenish the tissue it resides during normal homeostasis or during regeneration from a wound. Disease and aging leads to a depletion of these stem and progenitor cells, which can impede the ability of the body to regenerate itself. Thus, an understanding of the mechanisms of how tissue […]

Asymmetric stem cell division oriented by a local self-renewing signal

When stem cells divide, the two daughter cells have a choice. Commonly, one of the daughter cells becomes a new stem cell while the other one will be more specialized (or differentiated). This property — the ability to generate more stem cells (self-renewal) while making differentiated cells simultaneously — defines a stem cell. Stem cells […]

Mechanism of heart regeneration by cardiosphere-derived cells

In the process of a heart attack, clots form suddenly on top of cholesterol-laden plaques, blocking blood flow to heart muscle. As a result, living heart tissue dies and is replaced by scar. The larger the scar, the higher the chance of premature death and disability following the heart attack. While conventional treatments aim to […]

DECIPHERING THE INSTRUCTIONS FOR VERTEBRATE HSC SPECIFICATION AND AMPLIFICATION.

Hematopoietic stem cells (HSCs) are an important population of cells that continuously produce and replace blood and immune cells over the course of our lifetimes. These rare, self-renewing cells are the key element of bone marrow transplants, which are used to treat a variety of conditions including many forms of leukemia and solid tumors. Understanding […]
