Parkinson’s disease gene - parkin explored: Study

Researchers at the University at Buffalo have discovered how mutations in the parkin gene cause Parkinson's disease, which afflicts at least 500,000 Americans and for which there is no cure. The results are published in the current issue of Nature Communications.

Researchers discover how mutations in parkin gene cause PD

Parkinson's disease researchers at the University at Buffalo have discovered how mutations in the parkin gene cause the disease, which afflicts at least 500,000 Americans and for which there is no cure.

Scientists establish HCV infection in liver-like cells derived from iPSCs

Hepatitis C, an infectious disease that can cause inflammation and organ failure, has different effects on different people. But no one is sure why some people are very susceptible to the infection, while others are resistant. Scientists believe that if they could study liver cells from different people in the lab, they could determine how genetic differences produce these varying responses. However, liver cells are difficult to obtain and notoriously difficult to grow in a lab dish because they tend to lose their normal structure and function when removed from the body.

Breakthroughs in Alzheimer’s disease research

Researchers are closer to understanding Alzheimer’s disease using a new stem cell technique. They have successfully replicated Alzheimer’s disease neurons with stem cells for the first time.

Scientists evaluate growth, differentiation and function of iPSC-derived NPCs in PD

Induced pluripotent stem cells (iPSC) are a promising avenue for cell replacement therapy in neurologic diseases. For example, mouse and human iPSCs have been used to generate dopaminergic (DA) neurons that improve symptoms in rat Parkinson's disease models. Reporting in the current issue of the Journal of Parkinson's Disease, a group of scientists from Japan evaluated the growth, differentiation, and function of human-derived iPSC-derived neural progenitor cells (NPCs) in a primate model, elucidating their therapeutic potential.

Stem cells show promise in treating blindness

A medical breakthrough was reported Monday in the journal The Lancet wherein the results of a therapy using human embryonic stem cells in two legally blind patients was described.

Pig iPSCs can safely incorporate into tissues without tumor formation

Pig stem cell research conducted by two animal scientists at the University of Georgia reveals a better way to determine the safety of future stem cell therapies than rodent-based models.

Researchers discover molecular marker for immediate precursors of blood stem cells

A research team led by Nancy Speck, PhD, professor of Cell and Developmental Biology at the Perelman School of Medicine at the University of Pennsylvania, has discovered a molecular marker for the immediate precursors of hematopoietic (blood) stem cells (HSCs) in the developing embryo, which provides much-needed insights for making these cells from engineered precursors.

New gene editing technique can heal sickle cell patients with their own cells

Researchers at the Salk Institute for Biological Studies have developed a way to use patients' own cells to potentially cure sickle cell disease and many other disorders caused by mutations in a gene that helps produce blood hemoglobin.

U-M scientists generate Dravet-derived neurons

Scientists investigating the fundamental cause of Dravet syndrome, a severe childhood epilepsy, have reprogrammed fibroblasts, a type of skin cell, from Dravet patients and generated patient-specific neurons.

Established human embryonic cell lines vary from newly derived stem cell lines

Established human embryonic cell lines, including those approved for federal research funding under former President George W. Bush, are different than newly derived human embryonic stem cell lines, according to a study by UCLA stem cell researchers.

Largest survey on genetic, epigenetic stability of stem cells

An international study, published today in the prestigious journal Nature Biotechnology, reveals more about human pluripotent stem cells and their genetic stability and has important implications for the development of therapies using these cells.

Rare syndrome's workings could help explain how brain wiring goes awry

Potential clues to how autism miswires the brain are emerging from a study of a rare, purely genetic form of the disorders that affects fewer than 20 people worldwide. Using cutting-edge "disease-in a-dish" technology, researchers funded by the National Institutes of Health have grown patients' skin cells into neurons to discover what goes wrong in the brain in Timothy Syndrome.

Most people with Timothy syndrome mutation have autistic symptoms

Neuroscientists at Stanford University School of Medicine have homed in on potential differences in autistic people's brain cells by studying brainlike spheres grown in an elaborate process from skin cells.

Scientists decode how Machado-Joseph disease arises

Neurodegenerative diseases represent one of the greatest challenges of our aging society. However, investigation into these diseases is made particularly difficult due to the limited availability of human brain tissue. Scientists from the Life & Brain Research Center and Neurology Clinic of Bonn University have now taken a roundabout path: They reprogrammed skin cells from patients with a hereditary movement disorder into so-called induced pluripotent stem cells (iPS cells) and obtained functional nerve cells from them.

Human pluripotent stem cells rely heavily on glycolysis to drive their metabolic activities

Human pluripotent stem cells, which can develop into any cell type in the body, rely heavily on glycolysis, or sugar fermentation, to drive their metabolic activities.

Cultured ES cells can self-organize into three-dimensional tissue-like structures

The possibility that functional, three-dimensional tissues and organs may be derived from pluripotent cells, such as embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), represents one of the grand challenges of stem cell research, but is also one of the fundamental goals of the emerging field of regenerative medicine.

Inserm researchers successfully rejuvenate cells from elderly donors

Inserm's AVENIR "Genomic plasticity and aging" team, directed by Jean-Marc Lemaitre, Inserm researcher at the Functional Genomics Institute, has recently succeeded in rejuvenating cells from elderly donors.

ESCs express genes linked with early germ cell specification

Ordinarily, embryonic stem cells exist only a day or two as they begin the formation of the embryo itself. Then they are gone. In the laboratory dish, however, they act more like perpetual stem cells - renewing themselves and exhibiting the ability to form cells of almost any type, a status called totipotency.
