Human cartilage glycoprotein-39 (HC gp-30) is a secretory protein of several types of cells including chondrocytes. It has been suggested to be a laboratory index of joint damage. Thirty-two patients with systemic sclerosis (SSc) and 22 age-matched controls were investigated. An increased serum HC gp-39 level was shown in SSc patients and was found to correlate with inflammatory indices. There was no correlation with modified Rodnan score, joint involvement, or duration of symptoms of SSc. The obtained results indicate for possible relationship of HCgp-39 to inflammation but do not suggest determination of HC gp-39 as clinically applicable index of articular involvement in SSc patients.

Unlabelled: Cartilage and joint damage can lead to cartilage degeneration. Bone marrow mesenchymal stem cells (BMSCs) have the potential to address cartilage damage. Hence, this study probed the mechanism of BMSC-extracellular matrix (BMSC-ECM) in promoting damaged chondrocyte repair by regulating the Notch1/RBPJ pathway.

Background: Meniscal injuries that fail to heal instigate catabolic changes in the knee's microenvironment, posing a high risk for developing posttraumatic osteoarthritis (PTOA). Previous research has suggested that human cartilage-derived progenitor cells (hCPCs) can stimulate meniscal repair in a manner that depends on stromal cell-derived factor 1 (SDF-1) pathway activity.
Hypothesis: Overexpressing the SDF-1 receptor CXCR4 in hCPCs will increase cell trafficking and further improve the repair efficacy of meniscal injuries.

Osteoarthritis (OA) is a prevalent joint disorder that is characterized by the degeneration of articular cartilage in synovial joints. Most of the current treatment options for this disorder tend to focus on symptom management rather than addressing the underlying progression of the disease. Cartilage tissue engineering has emerged as a promising approach to address the limitations of current OA treatments, aiming to regenerate cartilage and restore the natural function of affected joints.

Microtia is a congenital malformation characterized by underdevelopment of the external ear. While chondrocyte dysfunction has been implicated in microtia, the specific cellular abnormalities remain poorly understood. This study aimed to investigate mitochondrial dysfunction in microtia chondrocytes using single-cell RNA sequencing.

The diagnostic challenge necessitates a combination of clinical examination, imaging studies, and arthroscopy, considered the gold standard. Ligament injuries, particularly scapholunate ligament (SL), and TFCC lesions account for significant wrist instability and ulnar-sided wrist pain, respectively.
