Disease Focus: Metabolic Disorders
A CIRM Disease Team for the Treatment and Cure of Diabetes
This proposal is for the establishment of a group of faculty, staff and industrial partners to develop a proposal for a Diabetes Disease Team. Diabetes is one of the most devastating diseases. Inadequate blood glucose control results on many long term complications including: kidney disease, blindness, amputation and nerve damage. The diabetes epidemic affects almost […]
Engineered matrices for control of lineage commitment in human pancreatic stem cells
Patients with end-stage type 1 diabetes (T1D) can be effectively managed by allogeneic islet transplantation. However, a severe cadaveric organ shortage greatly limits use of this promising procedure. Stem cells have the potential to provide a solution to this bottleneck because of their ability to self-renew and differentiate into islet β-cells. Although progress has been […]
Generation of a functional thymus to induce immune tolerance to stem cell derivatives
Stem cell research offers the promise of replacing missing or damaged tissues in the treatment of disease. Stem-cell-derived transplants still face problems with rejection as in traditional organ transplants. Several drugs can prevent rejection but also suppress the immune system, leaving patients vulnerable to infections and cancer. To avoid rejection without using drugs requires re-educating […]
Gene therapy-corrected autologous hepatocyte-like cells from induced pluripotent stem cells for the treatment of pediatric single enzyme disorders
Liver transplantation (LT) has been used to treat a variety of liver diseases. Within hours after birth, neonates can present with disorders of the urea cycle (UCDs), the critical metabolic liver pathway needed to detoxify waste nitrogen from the diet and cellular turnover. The overall incidence of UCDs is estimated to be 1 in 8200 […]
Development of a cell and gene based therapy for hemophilia
Hemophilia B is a bleeding disorder caused by the lack of FIX in the plasma and affects 1/30,000 males. Patients suffer from recurrent bleeds in soft tissues leading to physical disability in addition to life threatening bleeds. Current treatment (based on FIX infusion) is transient and plagued by increased risk for blood-borne infections (HCV, HIV), […]
Preclinical and clinical testing of a stem cell-based combination product for insulin-dependent diabetes
Diabetes exacts a tremendous toll on patients, their families, and society. Autoimmune Type 1 diabetes, often called juvenile-onset diabetes, is caused by a person’s own immune system mistakenly destroying their insulin-producing cells in the pancreas, known as beta cells. When those beta cells are lost, the ability to produce insulin in response to consumed carbohydrates […]
iPSC-derived Hepatocytes as Platforms for Research in Viral Hepatitis and Non-alcoholic Steatohepatitis
Hepatitis C and fatty liver disease are the two most common liver diseases in California. Individuals from different backgrounds are susceptible to these liver diseases, but they have unique genetic profiles that may influence the severity of disease and the response to specific therapies. Technology now makes it possible to generate stem cells from a […]
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 […]
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 […]
Deciphering transcriptional control of pancreatic beta-cell maturation in vitro
The loss of pancreatic beta-cells in type 1 diabetes results in absence of insulin secreted by the pancreas, and consequently elevated blood sugar which leads to various long-term complications. Diabetic patients would benefit tremendously from availability of transplantable replacement beta-cells. Much of current research focuses on producing beta-cells from stem cells. Despite some progress, it […]
