  • induced pluripotent stem cells from a Spinal Muscular Atrophy patient
    Nature, 2009

    Abstract:

    Spinal Muscular Atrophy is one of the most common inherited forms of neurological disease leading to infant mortality. Patients have selective loss of lower motor neurons resulting in muscle weakness, paralysis and often death. Although patient fibroblasts have been used extensively to study Spinal Muscular Atrophy, motor neurons have a unique anatomy and physiology which may underlie their vulnerability to the disease process. Here we report the generation of induced pluripotent stem cells from skin fibroblast samples taken from a child with Spinal Muscular Atrophy. These cells expanded robustly in culture, maintained the disease genotype and generated motor neurons that showed selective deficits compared to those derived from the child’s unaffected mother. This is the first study to show that human induced pluripotent stem cells can be used to model the specific pathology seen in a genetically inherited disease. As such, it represents a promising resource to study disease mechanisms, screen new drug compounds and develop new therapies. The inherited disease Spinal Muscular Atrophy (SMA), one of the most common neurological disorders causing death in childhood, is caused by mutations in both copies of the SMN1 gene. Little is known about SMA pathogenesis, partly because it is unique to humans who have two versions of this gene — SMN1 and SMN2; rodents and other lab model candidates have just one. Now a new technique has been developed that creates a tool for studying SMA disease pathology at the cellular level. Skin fibroblasts from a child with SMA (and for comparison from his unaffected mother) were used to generate induced pluripotent stem (iPS) cell lines. They form neural progenitor cultures that can produce differentiated neural tissue and motor neurons that maintain the disease phenotype. The cultures also responded to drugs known to elevate the mutated protein associated with the disease. Similar iPS technology may be of value in the study of other genetic disorders such as Huntington's disease. This paper generates an iPS cell line from patients with Spinal Muscular Atrophy, an autosomal recessive genetic disorder that is one of the most common inherited forms of neurological disease in children.
