A. Confocal images showing distribution and depth of penetration of CPC +14A and CPC +14N in various rat knee tissues 24 h post-intra-articular injection. B. CPC uptake in different rat knee tissues 24 h after intra-articular injection. Data are shown as Mean ± standard deviation. Tissue GAG concentration is shown in blue. C. Correlation between intra-tissue uptake of CPCs and GAG concentration is plotted. The dotted line is the linear least squared fit and solid lines show 95% confidence intervals (Femoral cartilage: FC; Tibial cartilage: TC; Patellar cartilage: PC; Meniscus: M; Anterior crucial ligament: ACL; Posterior crucial ligament: PCL; Patellar tendon: PT; Quadriceps tendon: QT; Fat pad: FP).
