Ultrasound measurements. Normalized (A) lesion and (B) tendon cross-sectional area (CSA) and (C) linear fiber pattern score for fetal-derived Embryonic-like Stem Cells (fdESC) and placebo control (CONT) treated tendons at time points post treatment injection in weeks. Asterisks mark significantly lower (A, B) or significantly higher (C) values for fdESC than CONT treated tendons (one-tailed P < 0.05).
