Growth factors for clinical-scale expansion of human articular chondrocytes : Relevance for automated bioreactor systems [PDF]

, 2007
The expansion of chondrocytes in automated bioreactors for clinical use requires that a relevant number of cells be generated, starting from variable initial seeding densities in one passage and using autologous serum.

The chondrocyte primary cilium [PDF]

Osteoarthritis and Cartilage, 2014
The presence and role of primary, or non-motile, cilia on chondrocytes has confused cartilage researchers for decades. Initial explanations attributed a vestigial nature to chondrocyte cilia. Evidence is now emerging that supports the role of the chondrocyte primary cilium as a sensory organelle, in particular, in mechanotransduction and as a ...

Cellular and molecular response to mechanical articular cartilage injury [PDF]

, 2010
PhDJoint injures frequently involve structural damage to articular cartilage and the underlying subchondral bone. The outcome of acute joint surface defects (JSD) varies from spontaneous healing to the development of post-traumatic osteoarthritis (PTOA).

Single-cell RNA sequencing reveals different chondrocyte states in femoral cartilage between osteoarthritis and healthy individuals

Frontiers in Immunology
BackgroundCartilage injury is the main pathological manifestation of osteoarthritis (OA). Healthy chondrocyte is a prerequisite for cartilage regeneration and repair.

PKR Promotes Oxidative Stress and Apoptosis of Human Articular Chondrocytes by Causing Mitochondrial Dysfunction through p38 MAPK Activation—PKR Activation Causes Apoptosis in Human Chondrocytes

Antioxidants, 2019
Osteoarthritis (OA) is one of the most common types of arthritis in the elderly people. It has been known that chondrocyte apoptosis occurs in OA cartilage; however, the detailed molecular mechanism remains unclear.

Glycolytic enzyme PKM2 regulates cell senescence but not inflammation in the process of osteoarthritis

Acta Biochimica et Biophysica Sinica, 2023
Chondrocyte senescence is an important mechanism underlying osteoarthritis in the senile population and is characterized by reduced expressions of the extracellular matrix proteins. The involvement of glycolysis

Factors affecting outcome after autologous chondrocyte implantation for the treatment of osteochondral defects of the knee [PDF]

, 2015
Some studies on autologous chondrocyte implantation (ACI) have demonstrated little benefit over other techniques and few have demonstrated a lasting benefit.

In vitro and in vivo validation of human and goat chondrocyte labeling by green fluorescent protein lentivirus transduction [PDF]

, 2010
We investigated whether human articular chondrocytes can be labeled efficiently and for long-term with a green fluorescent protein (GFP) lentivirus and whether the viral transduction would influence cell proliferation and tissue-forming capacity.

Investigating the causes of chondrocyte death in septic arthritis [PDF]

, 2020
Septic arthritis is a feared disease that can lead to the destruction of joints and result in significant morbidity. It is caused by an infection within a joint and up to 65% of cases are secondary to Staphylococcus aureus.
