Stem cells, sometimes taken from embryos, are undeveloped cells that grow into the body's tissues and organs. Funding for research using them has been limited in many countries, including the United States.
During his wheelchair trek from Fort Kent to Kittery, Harris plans to gather signatures of those supporting stem cell research. After his trip, which begins Wednesday, he wants to take the signatures to Washington, D.C.
Harris says he has complete faith that the American medical system can keep stem cell research focused on the right purposes.
"I know our state, our country can differentiate between those with clandestine cloning and immoral utilitarian agendas and those with wonderful scientific research and a strong moral compass," said Harris, a former bodybuilder and licensed social worker.
"I have a dream that Maine will answer my prayers and help me walk again. I know the only way I can walk again is if (more) stem cell research is approved," he said.
Traveling with a support crew of two, Harris will operate a wheelchair that has a maximum speed of 7 mph. He expects the trip will take at least 10 days, but says he is willing to spend whatever time it takes.
