Figure 1.

Morphology of myoblasts derived from DM1 and control mouse models. Conditionally immortalized myoblasts were derived from the GPS muscle complex of DM1 mouse models. Myoblasts differentiated into contractile myotubes under low-serum conditions. Representative images of cultures during proliferation (Day -2), confluency (Day 0) and differentiation (Days 1, 3 and 7) are shown. Bar 100 µm.
