Osteoarthritis (OA) commonly results in compromised mobility and disability, thereby imposing a significant burden on healthcare systems. Cartilage injury is a prevalent pathological manifestation in OA and constitutes a central focus for the development of treatment strategies. Despite the considerable number of studies aimed at delaying this degenerative process, their outcomes remain unvalidated in preclinical settings. Recently, therapeutic strategies focused on angiogenesis have attracted the growing interest from researchers. Thus, we conducted a comprehensive literature review to elucidate the current progress in research and pinpoint research gaps in this domain. Additionally, it provides theoretical guidance for future research endeavors and the development of treatment strategies.

The activity of Wnt inhibitory factor 1 (WIF1) is reduced upon promoter methylation and is involved in cartilage degradation in osteoarthritis. This study aims to investigate the mechanism by which WIF1 methylation is involved in chondrocyte damage in ankylosing spondylitis (AS). A model of chondrocyte inflammatory injury in AS was constructed by stimulation with interleukin (IL)-17.

Osteoarthritis (OA) is one of the most common degenerative joint diseases in the elderly, increasing in prevalence and posing a substantial socioeconomic challenge, while no disease-modifying treatments available. Better understanding of the early molecular events will benefit the early-stage diagnosis and clinical therapy. Here, we observed the nucleus accumulation of ZBTB20, a member of ZBTB-protein family, in the chondrocytes of early-stage OA.

Myringoplasty is most commonly used to treat tympanic membrane (TM) perforation. Clinical data have shown that unexplained high-frequency (above 3 kHz) hearing loss often occurs after myringoplasty. In this paper, a finite element (FE) model of the partial external and middle ear (ME) of the human ear, which considers the actual perforation and TM implants, is developed to reveal the mechanical mechanism of high-frequency hearing loss after implantation of temporalis fascia and cartilage commonly used in myringoplasty.

Articular cartilage lacks the capacity for self-repair after injury, rendering autologous chondrocyte transplantation a crucial treatment option for severe cartilage damage. However, the in vitro expansion of chondrocytes in elderly patients poses challenges, particularly due to inadequate cell numbers and rapid phenotypic loss, often exacerbated by the use of animal-derived serum. In this study, we propose the utilization of human autologous serum (HAS) as a supplement in the in vitro cell culture to preserve the phenotype of chondrocytes isolated from the same patient.
