Fig. 4From: Donor age affects proteome composition of tenocyte-derived engineered tendonImmunohistochemistry and collagen content measurement. Immunostainning of calponin on young (n = 7) (a) and old (n = 6) (b) tendon constructs showed a marked staining in old construct. Significantly higher (* p < 0.05) intensity of calponin staining (c) and higher collagen content (d) was identified in old tendon constructsBack to article page
