Biography

The focus of Dr. Peduzzi’s work is adult stem cells and their potential in the treatment of brain and spinal cord injuries and radiotherapy-induced brain damage. As an expert on adult stem cells, she has testified at the US Senate Committees on 3 different occasions on how autologous stem cells could revolutionize medicine. Using a person’s own cells avoids the problems of rejection, tumor formation and ethical concerns. Adult stem cells from the olfactory mucosa located inside the nasal cavity have several advantages. This tissue can be obtained using minimally invasive methods and the normal fate of these stem cells is neurons. Her collaborators in Portugal found that this tissue caused functional improvement in people with chronic, severe spinal cord injury when combined with BIONT rehabilitation (Lima et al., 2010). Her studies in rats revealed that functional improvement only occurred when the olfactory stem cells were from rats that were identical genetically. These stem cells can be delivered into the cerebrospinal fluid that surrounds the brain and spinal cord using a routine medical procedure (spinal tap) to reach areas of damage. Olfactory mucosa stem cells may be the best method to treat any type of neural injury or disease. Rehabilitation in the form of exercise and environmental enrichment (Fischer & Peduzzi, 2007) is needed to reveal the potential of the stem cell treatment.
