Couple give embryos, ‘hope’ to UM in fight against rare disease – The Detroit News

Alexandra Cellucci was 28 when she was diagnosed with neurofibromatosis, a rare genetic disease that causes noncancerous tumors to growon thebody's nervous tissues. She was also eight months pregnant at the time, but she would eventually delivera healthy baby girl.

Neurofibromatosis,known as NF for short,runs in Cellucci'sfamily, so sheknew her daughter could have the diseaseand she could pass it on to futurechildren. So sheand her husband, Marc, used reproductive medicine to conceive another baby, hadthe embryostested for the gene that causes NFand had doctors implantembryos in her womb without the mutatedgene.

Cellucci, now 35, never got pregnant again, despite many attempts. She and her husband have since learned their daughter Maible, now6,also carriesthe gene for NF2, one of the three forms of the disease. The day before Maible's birthday last November,the girl asked if she had the disease. Cellucci said she told her yes and that she would be OK.

That's why the Massachusetts coupledonated seven embryos with the NF2 gene to the University of Michigan soresearchers could create an embryonic stem cell line that other researchers could study, with the hope of one day discovering a breakthrough. In a perfect world, such a development would come before their daughter endures any symptoms.

I just wanted hope," said Cellucci, who had surgery last monthto remove a benigntumorbehind her eye. "They could possibly find a cure for (Maible) ... and offer hope for other families."

UM researchers have turned the Celluccis' embryos intothe firststem cell line that models NF2, which is one of the more rare forms of the disease. Besides the tumor growth, NF2 comes with a host of issues, including hearing loss, ringing in the ears and loss of balance. Symptoms typically appear in the teen years.

The embryonic stem cell line modeling the disease, created by ProfessorGary Smith, director ofthe MStem Cell Laboratories,has been acceptedonto the National Institutes of Health Human Embryonic Stem Cell Registryforother scientists to study and make discoveries around interventions anda possible cure. Another line also is under review.

Researchers can apply to access the stem cell lines on thefederal registryto study how diseases form and develop, with the aim of finding ways to better understand, treat, delay and possibly even cure diseases.

Smith has derived all of UM's56embryonic stem cell lines on the national registry, including 36 disease-specific lines. Hesaid the personal stories behind all of those stem cell lines are important.

"We just don't do science to do science," Smith said. "We do science to help others. Here is a family that recognizes that. Sometimes that gets lost on people. ... We really do want to help people."

The NF2 stem cell line comes as neurofibromatosis scientists andclinicians prepare to gather next month for their annual conference in San Francisco.

It also comes as Detroitbusinessman andCleveland Cavaliers ownerDan Gilbert has used philanthropy to support the small research community of neurofibromatosis. His 23-year-old son, Nick, was born with neurofibromatosis type 1.

NF2 afflicts1 in 33,000 people worldwide, while NF1 is more common, occurringin 1 in 3,000 to 4,000 people, according to the National Institutes of Health. NF1 typically begins in childhood and leads to skin changes and bone deformity.Schwannomatosis, the rarest type of NF, causes intense pain.

Gilbert, who suffered a stroke in late May,has spoken about neurofibromatosis and also about howNick, a Michigan State University student, hadto undergobrain surgery in 2018 to remove tumors.

Gilbert, a billionaire, has invested $64 million over the yearsthrough the Gilbert Family Foundation, including $12 million for gene therapy initiatives to address the underlying cause of NF1 and $11 million for vision loss in NF1 patients, which Nick grapples with, according toYooRi Kim, the foundation's scientific officer.

"With deeper understanding with each of these diseases that we've obtained over time, it's becoming more and more clear that the strategies that you would use to help each of thosepatients are going to look different," Kim said.

Even so, she said there is excitement about advances in research on other forms of NF, such as the stem cell line modeling NF2.

There arefour embryonic stem cell lines on the registry that model NF1, but theline UM created is the first for the research community studying NF2,according to Smith.

"It means a lot to the couplethat somebody is using something that otherwise would have been discarded and instead trying to make it something that can be used worldwide to understand this disease better," he said.

The stem cell line hasbeen applauded by Sally Temple, scientific director of the Neural Stem Cell Institute in Rensselaer,New York, which uses stem cell technologies to develop therapies that affect the nervous system.

"It's a really wonderful and generous for the parents to do," said Temple, who is also aUM adjunct professor in the ophthalmology department. "When you make these human embryonic stem cell lines, they are essentially a resource forever for the community. It's available and it will be there for (researchers)to use forever in the future. It's not a one-time donation."

She added that this is important for the NF2 community since it is such a devastating disease.

Marc Cellucci is beyond thrilled, and hopeful of the possibilities for the stem cell line that he and his wife helped create and what it could do for his daughter, wife, in-laws and so many others with NF.

It all has to start somewhere, said Cellucci,where the scientific breakthroughs happen, and the miracles begin.
