Bone and Cartilage Biology.

I sincerely thank the authors for their contributions to this Special Issue and believe that these notions would help to further our understanding of molecular and cellular mechanisms of bone and cartilage biology, as well as contribute to the development of therapeutic strategies for bone and cartilage diseases. Recent technical and conceptual advances in molecular and cellular biology have dramatically advanced bone and cartilage biology. This Special Issue aims to provide novel notions for skeletal development, and bone and cartilage diseases. This progress has also improved our understanding of the molecular pathogenesis of bone and cartilage diseases, including osteoporosis, osteoarthritis, and rheumatoid arthritis.
