Research Abstract |
Protein transportation in cartilage has been believed to be due to diffusion because there is no blood vessel in cartilage. In the present study, we revealed that low-density lipoprotein receptor-related protein-1(LRP-1) transports connective tissue growth factor/CCN family 2 (CTGF/CCN2/CCN2)in cartilage by transcytosis, indicating that this mechanism is a new protein transport system in cartilage. We also uncovered that cartilage-specific defect of LRP-1 resulted in skeletal disorders.
