Modeling cardiovascular diseases using iPSCs is becoming a common approach to understand the genetic contribution4-6. Some unanticipated difficulties of obtaining cell samples from patients, especially young children, can be avoided by offering the option of a non-invasive approach such as a urine collection. In this young patient population, it is often difficult to collect a volume of urine sufficient to yield enough urine cells for reprogramming. Coaching the young patients to drink fluids 30 min prior to t...

Cardiomyopathy is the second leading cause of death in patients with Duchenne and Becker muscular dystrophy (MD). Although mutations in the X-linked dystrophin gene occur in 1:3,500 male births, very little is known about the molecular and cellular events leading to progressive cardiac muscle damage. Human induced pluripotent stem cells derived from muscular dystrophy patients have emerged as a novel tool to study the underlying disease mechanisms and to use for drug screening1,2.
The anticipated discomfort of skin biopsies or blood samples may dissuade young patients and/or their guardians to give consent for study participation. Urine samples are a non-invasive source of somatic cells that are amendable to reprogramming methods. We have recently shown that urine cells collected from muscular dystrophy patients may be cultured and efficiently reprogrammed into iPSCs using retroviral transduction with the Yamanaka factors (Oct3/4, Sox2, Klf4, and c-Myc; OSKM)1. The disadvantage of retroviral gene delivery is the random integration of the reprogramming genes into the host chromosomes. To overcome this limitation, we have used the non-integrating Sendai virus for urine cell reprogramming.
This protocol details the Sendai virus reprogramming of isolated urine cells from muscular dystrophy patients which can then be differentiated into cardiomyocytes or other cell types for further study. This protocol can also be adapted for other patient specific diseases.

generation of induced pluripotent stem cells from muscular dystrophy patients: efficient integration-free reprogramming of urine derived cells

Dystrophic cardiomyopathy is a poorly understood consequence of muscular dystrophy. Generating induced Pluripotent Stem Cells (iPSCs) from patients with muscular dystrophy is an invaluable cellular source for in&#160;vitro disease model systems and can be used for drug screening studies. Patient-derived urine cells have been used in successful reprogramming into induced pluripotent stem cells in order to model dystrophic cardiomyopathy1. Addressing the safety concerns of integrating vector systems, we present a protocol using a non-integrating Sendai virus vector for transduction of Yamanaka factors into urine cells collected from patients with muscular dystrophy. This protocol generates fully reprogrammed clones within 2&#8211;3 weeks. The pluripotent cells are vector-free by passage-13. These dystrophic iPSCs can be differentiated into cardiomyocytes and used either to study disease mechanisms or for drug screening.

Most progenitor cells isolated from human urine are positive for uroepithelial progenitor and pericyte markers such as CD44, CD73, and CD146 (97.37%, 97.09%, and 97.3% respectively; Figure 1A and 1B). These cells also expressed other mesenchymal markers such as alpha-smooth muscle actin and vimentin (Figure 1B). RT-PCR analysis gives evidence of a mixed population of cells in the cultures in that there is weak expression of Cytokeratin-7 (CK-7) and Uroplakin (UP)-Ia &#38...
