| Abstract |
Our study is the first to demonstrate the ability to generate iPS cells from a mouse model of Pompe disease. Initially, mouse tail tip fibroblasts were harvested from male, 8-week-old (GAA) knockout mice, and three reprogramming factors (Oct3/4, Sox2 and Klf4) were transfected into the isolated donor cells using a retroviral vector. These iPS cells also showed decreased levels of GAA enzymatic activity and strong positive staining with periodic acid-Schiff (indicating the accumulation of glycogen) and acid phosphatase (lysosomal activation marker). Pompe-iPS cells were differentiated into skeletal muscle cells in Matrigel®-coated plates. Spindle-shaped skeletal muscle cells were successfully generated from Pompe-iPS cells and showed spontaneous contraction and positive staining with the myosin heavy chain antibody. Electron microscopic analysis of the skeletal muscle cells showed typical morphological features, including Z-bands, I-bands, A-bands and H-bands, which were visible in wild-type and Pompe cells. Furthermore, Pompe skeletal muscle cells accumulated massive glycogen in lysosomes. This study indicates that the iPS and skeletal muscle cells generated in this study could also be a useful disease model for studies investigating the pathogenesis and treatment of skeletal muscle in Pompe disease.
