Jeanne Loring likes to say shes been to space without her feet even leaving the ground.

Just weeks ago, the Scripps Research Institute professor of molecular medicine sent some of her own genetically mapped cells to space as part of first-of-its-kind research to study the progression and onset of Parkinsons disease, multiple sclerosis and other neurodegenerative diseases.

I love traveling. Ive been on all the continents, and so I figured, whats left? Loring said jokingly. I just jumped at the opportunity when I learned that it was possible.

In July, the cells arrived via cargo spacecraft at the International Space Station, where they remained under close observation for about a month 250 miles above Earth, and traveling at 17,500 miles per hour before they splashed back down to Earth last week.

The study is part of new National Stem Cell Foundation-funded neurodegeneration research to observe how cells communicate in microgravity in a way not possible on Earth, explained Paula Grisanti, founder and CEO of the foundation.

Its really pure exploration at this point, because theres no history of anybody doing this before, she said. Were paving the path.

Loring, a Del Mar resident who is one of the worlds leading experts in Parkinsons and a senior scientific advisor for the foundation, has been working with human-induced pluripotent stem cells since the technology was first discovered in 2006.

Called organoids, these cells are made from human skin tissue, which is put into a culture dish and turned into pluripotent stem cells, Loring explained.

Pluripotent stem cells only exist in culture dishes, they dont exist in our bodies, she said. Pluripotent means they can form any cell type in the body so for Loring, that meant forming nerve cells to create brain-like structures.

Its hard to study peoples brains, Loring said. You can do all this external stuff like they do with physical exams, but theres not any window into the brain so this is providing a sort of brain avatar.

Organoids provide a stand-in for the brain that can be studied by researchers, Loring explained. They make connections with each other, the cells talk to each other, so in a lot of ways, its a really good model of the brain, she added.

Moreover, the organoids mimic the brains of people with MS and Parkinsons.

Loring has been working with these organoids for years through Aspen Neuroscience, a San Diego-based company she co-founded that is working to create the worlds first personalized cell therapy for Parkinsons, using a patients own cells so they dont have to worry about rejection. Clinical trials may start as early as next year, she said.

For the last four years, the foundations team of bicoastal researchers has been working together to study these organoids in space.

While an experiment in space presents its own challenges, Loring said its worth the work, as researchers hope to gain valuable and unique insight into how disorders like Parkinsons and MS develop. You can see them interacting and talking to each other in 3-D in a way that you cannot on Earth, Grisanti said.

Along with Lorings healthy organoids, which are used as a control, organoids derived from patients with Parkinsons and MS were sent to the space station, while the entire experiment was replicated on Earth.

Specifically, researchers are studying the neuroinflammation in the organoids, which is like when the immune system in the brain is overactive, Grisanti explained.

What we hope to find is a point at which things start to go wrong in those neurodegenerative diseases, where we could then intervene with a new drug or cell therapy, she said. And were seeing signs that that happens more in space than it does on the ground, so it helps create the type of interaction that you would see early in a neurodegenerative disease.

Grisanti said they hope to be able to use this research to develop a new drug or cell therapy to treat these disorders and potentially other neurodegenerative diseases in the future.

I think weve cracked the door open, but weve got some more flying to do, she added.
