NEW YORK, NY -- The New York Stem Cell Foundation (NYSCF) and Beyond Batten Disease Foundation (BBDF) have partnered to develop stem cell resources to investigate and explore new treatments and ultimately find a cure for juvenile Batten disease, a fatal illness affecting children.

NYSCF scientists will create induced pluripotent stem (iPS) cell lines from skin samples of young people affected by juvenile Batten disease as well as unaffected family members. IPS cell lines are produced by artificially "turning back the clock" on skin cells to a time when they were embryonic-like and capable of becoming any cell in the body. Reprogramming juvenile Batten iPS cells to become brain and heart cells will provide the infrastructure needed to investigate what is going wrong with the cells adversely affected by the disease. Thus far, efforts to study juvenile Batten disease have been done using rodent models or human skin cells, neither of which accurately mimic the disease in the brain, leaving researchers without proper tools to study the disease or a solid platform for testing drugs that prevent, halt, or reverse its progression. This will be the largest and first genetically diverse collection of human iPS cells for a pediatric brain disease.

In addition to working with BBDF to actively recruit patients and families to donate skin samples, Batten Disease Support and Research Association (BDSRA) is providing resources and technical support, spreading awareness among academic scientists, and notifying its Pharmaceutical partners. Together, BBDF and BDSRA will ensure that juvenile Batten disease and other researchers are aware of and utilize the 48 stem cell lines resulting from this collaboration to further juvenile Batten disease research worldwide.

"We know the genetic mutations associated with juvenile Batten disease. This partnership will result in stem cell models of juvenile Batten, giving researchers an unprecedented look at how the disease develops, speeding research towards a cure," said Susan L. Solomon, NYSCF Chief Executive Officer.

"Working with NYSCF to generate functional neuronal subtypes from patients and families is a stellar example of one of our key strategies in the fight against juvenile Batten disease: creating resource technology with the potential to transform juvenile Batten disease research and accelerate our timeline to a cure," said Danielle M. Kerkovich, PhD, BBDF Principal Scientist.

Juvenile Batten disease begins in early childhood between the ages of five and ten. Initial symptoms typically begin with progressive vision loss, followed by personality changes, behavioral problems, and slowed learning. These symptoms are followed by a progressive loss of motor functions, eventually resulting in wheelchair use and premature death. Seizures and psychiatric symptoms can develop at any point in the disease.

Juvenile Batten disease is one disorder in a group of rare, fatal, inherited disorders known as Batten disease. Over 40 different errors (mutations) in the CLN3 segment of DNA (gene) have been attributed to juvenile Batten disease. The pathological hallmark of juvenile Batten is a buildup of lipopigment in the body's tissues. It is not known why lipopigment accumulates or why brain and eventually, heart cells are selectively damaged. It is, however, clear that we need disease-specific tools that reflect human disease in order to figure this out and to build therapy.
