UC Irvine researchers create new stem cell-derived cell type for treatment of Alzheimer's

UC Irvine researchers have created a new stem cell-derived cell type with unique promise for treating neurodegenerative diseases such as Alzheimer's.

Caltech-led team discovers enzyme responsible for neural crest cell development

During the early developmental stages of vertebrates-animals that have a backbone and spinal column, including humans-cells undergo extensive rearrangements, and some cells migrate over large distances to populate particular areas and assume novel roles as differentiated cell types.

CIBMTR renews Stem Cell Therapeutics Outcomes Database contract with HRSA

The Medical College of Wisconsin Center for International Blood and Marrow Transplant Research successfully competed for, and was awarded, renewal of the Stem Cell Therapeutics Outcomes Database contract with the U.S. Health Resources and Services Administration.

New video-protocol details steps to generate human iPSCs from peripheral blood cells

Stem cells are a valuable resource for medical and biological research, but are difficult to study due to ethical and societal barriers. However, genetically manipulated cells from adults may provide a path to study stem cells that avoid any ethical concerns. A new video-protocol in JoVE (Journal of Visualized Experiments), details steps to generate human induced pluripotent stem cells (iPSC) from cells in the peripheral blood.

IPSCs may be a viable source of patient-specific articular cartilage tissue

A team of Duke Medicine researchers has engineered cartilage from induced pluripotent stem cells that were successfully grown and sorted for use in tissue repair and studies into cartilage injury and osteoarthritis.

New hope for mitochondrial disease sufferers

Scientists have succeeded in replacing mitochondrial DNA in human oocytes, which they hope will lead to the procedure being developed for use in patients with mitochondrial diseases.

Researchers zero in on process by which stem cells maintain proper undifferentiated state

The ability of embryonic stem cells to differentiate into different types of cells with different functions is regulated and maintained by a complex series of chemical interactions, which are not well understood. Learning more about this process could prove useful for stem cell-based therapies down the road. New research from a team led by Carnegie's Yixian Zheng zeroes in on the process by which stem cells maintain their proper undifferentiated state.

mTor molecule plays a significant role in myeloid differentiation

University of Illinois cell and developmental Biology professor Fei Wang and colleagues have created a new technique to study how myeloids, a type of blood stem cell, become the white blood cells important for immune system defense against infections and tissue damage.

UNM Cancer Center scientist to continue histone modification study

While every one of our cells contains all of our genetic information, each type of cell uses only specific parts of that information to make its proteins. Uncovering more about the mechanism that directs which particular pieces of genetic information the cell uses is the research focus of Mary Ann Osley, PhD, University of New Mexico Professor of Molecular Genetics and Microbiology and Co-Leader of the Cancer Biology and Biotechnology Program at the UNM Cancer Center.

Stem cell study may help to unravel how genetic mutation leads to Parkinson's symptoms

By reprogramming skin cells from Parkinson's disease patients with a known genetic mutation, researchers at the Salk Institute for Biological Studies have identified damage to neural stem cells as a powerful player in the disease.

Reprogrammed endothelial cells for treatment of vascular disorders

A research team at Weill Cornell Medical College has discovered a way to utilize diagnostic prenatal amniocentesis cells, reprogramming them into abundant and stable endothelial cells capable of regenerating damaged blood vessels and repairing injured organs.

Animal research shows promise in treating AD, brain damage and heart problems resulting from SCIs

New animal studies provide additional support for investigating stem cell treatments for Parkinson's disease, head trauma, and dangerous heart problems that accompany spinal cord injury, according to research findings released today.

Study identifies epigenetic changes that occur in adult stem cells to generate different body tissues

The team led by Manel Esteller, director of the Cancer Epigenetics and Biology Program in the Bellvitge Biomedical Research Institute (IDIBELL), Professor of Genetics at the University of Barcelona and ICREA researcher, has identified epigenetic changes that occur in adult stem cells to generate different body tissues. The finding is published this week in The American Journal of Pathology.

Experimental stem cell treatment improves vision in blind mice

An experimental treatment for blindness, developed from a patient's skin cells, improved the vision of blind mice in a study conducted by Columbia ophthalmologists and stem cell researchers.

Common RNA pathway links frontotemporal lobar dementia with ALS

Two proteins previously found to contribute to ALS, also known as Lou Gehrig's disease, have divergent roles. But a new study, led by researchers at the Department of Cellular and Molecular Medicine at the University of California, San Diego School of Medicine, shows that a common pathway links them.

Study finds differences and similarities between iPSCs and cancer cells

UC Davis investigators have found new evidence that a promising type of stem cell now being considered for a variety of disease therapies is very similar to the type of cells that give rise to cancer. The findings suggest that although the cells -- known as induced pluripotent stem cells (iPSCs) -- show substantial promise as a source of replacement cells and tissues to treat injuries, disease and chronic conditions, scientists and physicians must move cautiously with any clinical use because iPSCs could also cause malignant cancer.
