Fig. 5. Relationship between the number of LP cells injected and the number of dystrophin-positive myofibers observed at 7 days post-injection. The greater slope of the CD34⁺ population's relationship re-emphasizes its higher level of regeneration efficiency. Relatively linear and predictable increases in number of dystrophin-positive myofibers generated with respect to injected cell number were observed for all populations (R²: 0.676, 0.758, 0.736, and 0.497 for Sca-1^-, Sca-1⁺, CD34^-, and CD34⁺, respectively).
