Fig. 4From: Identifying potential patient-specific predictors for anterior cruciate ligament reconstruction outcome – a diagnostic in vitro tissue remodeling platformPro-collagen I content decreased with increasing patient age, with an apparent patient cut-off age around 25 years. Patient-specific human pro-collagen I α1 content per micro-tissue was measured using ELISA and analyzed with respect to patient age. Outliers in cell lysate content are indicated by the open symbols . n = 28Back to article page
