Figure 2. FDL tendons exhibit microstructural changes in composition without a change in cellular proliferation with age.

Figure 2

Yellow arrows indicate an observable collagen fiber re-alignment (perpendicular ‘score’ marks in the tendon) in the aged tendon seen with Alcian Blue/ Hematoxylin/ Orange G staining in 1D, and a change in composition with picrosirius red staining in 1E. No proliferating cells are seen with PCNA staining within the tendon body in young or aged FDL tendons (1C, F).
