Sniffing Out Parkinson’s Disease with Stem Cells

Stem Cells found in the nose produce neurons that may be able to treat neurodegenerative diseases.

German scientists at the University of Bielefeld and Dresden University of technology have produced neurons from inferior turbinate stem cells [ITSC], a cell type that is typically discarded during sinus surgery, as a potential treatment for Parkinson’s disease.  After transplanting the ITSCs into an animal model suffering from Parkinson’s, the researchers observed full functional restoration and significant behavioral recovery in the subjects without any adverse side effects.

New York Times: The Eruption of Stem Cell Therapies.

Mr. Edgar Irastorza is one of thousands of people already benefiting from the progression of stem cell based therapies.

As reported on the front page of the New York Times Science section, clinical applications of stem cell based therapies are accelerating at a rate that will revolutionize the medical field in a matter of years.  In the United States alone, there are currently over 4000 therapies in clinical trials for the treatment of heart disease, blindness, spinal cord injuries, diabetes, H.I.V., and other diseases, injuries, and traumas.

Stem Cells Immune to Damage from Leukemia Chemotherapy

Certain stem cells have been found to be immune to the bone-degenerative side effects of chemotherapy used against leukemia.

A research team, led by Dr. Eric Darling of Brown University, has found a potential source of stem cells to protect children with acute lymphoblastic leukemia against the adverse effects of the chemotherapy drug methotrexate (MTX).  Adipose-derived stem cells, which appear to be impervious to the bone-degenerative side effects of MTX, may allow children to undergo the chemotherapy treatment and then regain the lost bone tissue afterwards.

Researchers Utilize Stem Cells to Study Parkinson’s Disease

Stem Cells could lead to personalized treatments for diseases involving genetic mutations

Recently, researchers team from Sanford-Burnham’s Del E. Webb Center for Neuroscience, Aging, and Stem Cell Research and MIT’s Whitehead Institute for Biomedical Research used stem cells from patients with Parkinson’s disease to show that a genetic mutation is partly responsible for cell death in the patients’ nervous system.  This study exhibits a novel ability of stem cells to act as a model through which researchers can better understand diseases and develop better outcomes.

Stem Cell Advance Gives Hope for Neurodegenerative Treatment

Scientists in the US (UC, UCSD) and China (Wuhan) have found a way to convert stem cells into functional neurons. The researchers were able to suppress an RNA-binding protein, inducing the stem cells to become neurons. This gives hope for a treatment for neurodegenerative diseases such as Huntington’s, Parkinson’s, Alzheimer’s, Multiple Sclerosis, and Amyotrophic Lateral Sclerosis (ALS or Lou Gehrig’s disease), which will afflict one in four Americans over their lifetime.

Autologous Stem Cells Utilized to Recover Motor Function in Parkinson’s Model

Parkinson’s disease is a progressive degenerative disorder of the nervous system that affects movement and motor function. Some common symptoms of the disease are tremors and difficulty walking, caused by degeneration of neurons that produce dopamine (also know as “dopaminergic neurons”).

In a recent study, Takuya Hayashi headed a team of researchers at the RIKEN Center for Molecular Imaging Science with the goal of regenerating  dopaminergic neurons  using autologus stem cells (or stem cells derived from a patient’s own body).  The researchers directed the stem cells to differentiate into dopaminergic neurons in an animal model; monkeys suffering from Parkinson’s disease.

Progress in Differentiation Accelerates Stem Cell Treatments for Alzheimer’s and Parkinson’s

Researchers at Gutenberg University Mainz have found a way to generate human neurons from pericytes, cells found in the central nervous system, through the use of stem cells. The researchers have observed the process of differentiation that stem cells undergo when they become a new type of cell, and have induced stem cells to go through this process. Therefore, these cells have been directed to become new neuronal cells.
