Figure 5. Histomorphometry and CTGF immunoreactivity in distal supraspinatus tendons.
(A) Cellularity scores of aged high repetition low force (HRLF) and aged normal control (NC) rat tendons. (B) Cellularity scores in young adult rat tendons. *p<0.05, compared to NC. (C) CTGF in distal supraspinatus tendon of aged NC, and (D) aged 12-week HRLF rat. (E) CTGF in distal supraspinatus epitendon of aged 12-week HRLF rat. Epi = epitendon, endo = endotendon; para = paratendon. Scale bar = 50 µm.
