Scientists measure communication between stem cell-derived motor neurons, muscle cells

In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure communication between stem cell–derived motor neurons and muscle cells in a Petri dish.

The study provides an important proof of principle that functional motor circuits can be created outside the body using these neurons and cells and that the level of communication, or synaptic activity, between them can be accurately measured by stimulating the motor neurons with an electrode and then tracking the transfer of electrical activity into the muscle cells

Neuralstem gets FDA OK for Stem cell trial for ALS treatment

Neuralstem Inc. has received the green light to begin the first human stem cell trial to treat Amyotrophic Lateral Sclerosis (ALS), often referred to as Lou Gehrig’s disease. The company’s stock soared on the news.

Neuralstem has only received approval for the first stage of the trial that would consist of 12 patients who will receive stem cell injections in the lumbar area of the spinal cord.

Neuralstem said the trial will be under the direction of principal investigator Dr. Eva L. Feldman, Director of the University of Michigan Health System ALS Clinic and the Program for Neurology Research & Discovery.

Emory Conducting Landmark Study to Treat ALS

Emory University researchers are participating in a groundbreaking clinical trial to treat patients with amyotrophic lateral sclerosis (ALS) using human neural stem cells.

The Phase 1 trial, will assess the safety of stem cells, and the surgical procedures and devices required, for multiple injections of the cells directly into the spinal cord.

“This is the first U.S. clinical trial of stem cell injections into the spinal cord for the treatment of ALS,” says principal researcher Jonathan Glass, professor of neurology in the School of Medicin, and director of the Emory ALS Center. “Our main goal in this early phase is to

Stem cell study could aid motor neurone disease research

Scientists have discovered a new way to generate human motor nerve cells in a development that will help research into motor neurone disease.

A team from the Universities of Edinburgh, Cambridge and Cardiff has created a range of motor neurons – nerves cells that send messages from the brain and spine to other parts of the body – from human embryonic stem cells in the laboratory.

It is the first time that researchers have been able to generate a variety of human motor neurons, which differ in their make-up and display properties depending on where they are located

Stem cells reduce degeneration in motor neurons

Japanese stem cell scientists have succeeded in slowing the deterioration of mice with motor neuron disease, possibly paving the way for human treatment, according to a new paper.

A team of researchers from the Kyoto University and Keio University transplanted specially created cells into mice with amyotrophic lateral sclerosis (ALS), also called Lou Gehrig’s, or motor neuron disease.

The progress of the creatures’ neurological degeneration was slowed by almost 8%, according to the paper, which was published on Friday in the journal Stem Cell Reports.
