SYNOPSIS OF AREA OF INTEREST: Stem cell therapy on the effects of protein deficiencies that cause degenerative muscle diseases (muscular dystrophies) is the primary focus. We use cultured muscle cells, single fiber and whole muscle functional assays in rodent and canine models. The canine model of dystrophin deficiency allows for function assessment of muscle strength and response to cellular, gene or pharmacologic agents potentially useful in the treatment of humans with muscular dystrophy.

DETAILED AREA OF INTEREST: Duchenne muscular dystrophy (DMD) afflicts 1 in 3300 males born each year in the US causing devastating weakness, contractures and early death. Despite over a century of research there is no cure for this inherited disease stemming, in part, from the lack of animal models that reflect both the genotype and phenotype of the human condition. Recently, we and others have described the golden retriever muscular dystrophy (GRMD) dog model. Affected dogs display progressive clinical deterioration and death by 1-2 years of age reflective of humans with DMD. Although effective treatment does not yet exist, novel therapeutic strategies, particularly stem cell therapy, hold great promise. Recently, an Italian group made world-wide headlines when they reported that intra-arterial delivery of perivascular stem cells in GRMD dogs ameliorated dystrophic muscle pathology. Enthusiasm for this discovery has been tempered by the fact that the perivascular stem cells were derived from neonatal muscle tissue – a non-renewable problematic resource. In addition, such cells have only a limited number of cell divisions limiting their capability to produce long-term benefit without repeated infusions. Coincident with the Italian report came the remarkable finding by A. Atala and colleagues at the WFIRM of stem-like properties from cells derived from amniotic fluid. Stem cells derived from the amniotic membrane hold similar promise. We are currently evaluating the therapeutic potential of stem cells derived from canine amniotic membrane by measuring their migration and engraftment abilities in immunodeficient mice.
