Figure 4: Cell transplantation of ES-derived myogenic precursors improves contractility of dKO:mdx/utrn-/- dystrophic mouse model. (A) Representative examples of isometric force-tracking in tibialis anterior (TA) muscles that had been injected with cells or PBS (black and gray lines, respectively). (B-D) Effect of cell transplantation on absolute (F0) (B), and specific sF0 (sF0=F0 normalize to CSA) force (C,D). Average CSA (E) and weight (F) of analyzed muscles. Error bars represent S.E.M. from a total of 5 transplanted mice *p<0.01
