TAMPA Researchers at the University of South Florida show in a new study that bone marrow stem cell transplants helped improve motor functions and nervous system conditions in mice with the disease amyotrophic lateral sclerosis (ALS) by repairing damage to the blood-spinal cord barrier.

In a study recently published in the journal Scientific Reports, researchers in USFs Center of Excellence for Aging and Brain Repair say the results of their experiment are an early step in pursuing stem cells for potential repair of the blood-spinal cord barrier, which has been identified as key in the development of ALS.

USF Health Professor Svitlana Garbuzova-Davis, PhD, led the project.

Using stem cells harvested from human bone marrow, researchers transplanted cells into mice modeling ALS and already showing disease symptoms. The transplanted stem cells differentiated and attached to vascular walls of many capillaries, beginning the process of blood-spinal cord barrier repair.

The stem cell treatment delayed the progression of the disease and led to improved motor function in the mice, as well as increased motor neuron cell survival, the study reported.
