The aim of the study was to evaluate whether there is a superior clinical effect of artificial cervical arthroplasty compared with anterior cervical discectomy and fusion (ACDF) for the treatment of one-level cervical degenerative disc disease (CDDD). A comprehensive literature search of multiple databases, including PubMed, ScienceDirect, Scopus, Embase,(More)
Osteoarthritis (OA) is the most prevalent degenerative joint disease. The highly regulated balance of matrix synthesis and degradation is disrupted in OA, leading to progressive breakdown of articular cartilage. The molecular events and pathways involved in chondrocyte disfunction of cartilage in OA are not fully understood. It is known that(More)
This study employed transforming growth factor beta 3 (TGF-β3) induction of the C3H10T1/2 mesenchymal stem cell (MSC) line to construct an in vitro chondrogenic differentiation model for MSCs. A C3H10T1/2 MSC cell line was cultured, amplified, and the seventh generation of cells was centrifuged to construct pellets, which were divided into a non-induced(More)
Chondrogenic differentiation of mesenchymal stem cells is regulated by many different pathways. Recent studies have established that hypoxia and epigenetic alterations potently affect expression of chondrogenesis marker genes. Sox9 is generally regarded as a master regulator of chondrogenesis and microRNA-124 (miRNA-124) regulates gene expression in murine(More)
OBJECTIVE To observe the genes expression of hypoxia inducible factor lα (HIF-1α) and HIF- 2α by inducing chondrogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) so as to provide a fundamental basis for HIF involving in the mechanism of chondrogenesis. METHODS High density pellet of hBMSCs was obtained by centrifugation and(More)
Hydrogel injection has been recently proposed as a novel therapy for disc degenerative diseases, with the potential to restore the spine motion and the intervertebral disc height. However, it remains unknown whether the new technique could also maintain the shock absorbing property of the treated intervertebral disc. In this study, 18 porcine lumbar(More)
