Hypoxia promotes redifferentiation and suppresses markers of hypertrophy and degeneration in both healthy and osteoarthritic chondrocytes [PDF]

, 2013
INTRODUCTION: Hypoxia is considered to be a positive influence on the healthy chondrocyte phenotype and cartilage matrix formation. However, hypoxia-inducible factors (HIFs) have been implicated in the pathogenesis of osteoarthritis (OA).

Minced cartilage implantation provides comparable outcomes to autologous chondrocyte implantation (ACI) for knee cartilage lesions: A matched‐pair analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare short‐term patient‐reported outcomes (PROMs) and revision rates between autologous hand‐minced cartilage implantation (MCI) and autologous chondrocyte implantation (ACI) for knee cartilage lesions. Methods All patients undergoing MCI or ACI at a single centre were retrospectively analysed from a prospectively maintained ...

Collagen‐membrane‐covered matrix‐associated chondrocyte implantation improves safety over periosteum‐covered MACI for large knee cartilage defects: A real‐world data analysis in the registry study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This registry study aimed to evaluate the safety and effectiveness of collagen membrane‐covered matrix‐associated autologous chondrocyte implantation (cMACI) versus periosteum‐covered MACI (pMACI) for large knee cartilage defects (Outerbridge III–IV, ≥4 cm²) in the femorotibial and/or patellofemoral joints with a minimum 2‐year follow ...

Transcription Factors in Cartilage Homeostasis and Osteoarthritis

Biology, 2020
Osteoarthritis (OA) is the most common degenerative joint disease, and it is characterized by articular cartilage loss. In part, OA is caused by aberrant anabolic and catabolic activities of the chondrocyte, the only cell type present in cartilage. These

Insulin-like growth factor I (IGF-1) Ec/Mechano Growth factor--a splice variant of IGF-1 within the growth plate. [PDF]

PLoS ONE, 2013
Human insulin-like growth factor 1 Ec (IGF-1Ec), also called mechano growth factor (MGF), is a splice variant of insulin-like growth factor 1 (IGF-1), which has been shown in vitro as well as in vivo to induce growth and hypertrophy in mechanically ...

Suppression of Hypertrophy During in vitro Chondrogenesis of Cocultures of Human Mesenchymal Stem Cells and Nasal Chondrocytes Correlates With Lack of in vivo Calcification and Vascular Invasion

Frontiers in Bioengineering and Biotechnology, 2021
ObjectiveHuman nasal septal chondrocytes (NC) are a promising minimally invasive derivable chondrogenic cell source for cartilage repair. However, the quality of NC-derived cartilage is variable between donors. Coculture of NC with mesenchymal stem cells

PTHrP regulates chondrocyte maturation in condylar cartilage [PDF]

, 2003
PTHrP is a key factor regulating the pace of endochondral ossification during skeletal development. Mandibular advancement solicits a cascade of molecular responses in condylar cartilage.

Stromal Cell-Derived Factor 1 Regulates the Actin Organization of Chondrocytes and Chondrocyte Hypertrophy

PLoS ONE, 2012
Stromal cell-derived factor 1 (SDF-1/CXCL12/PBSF) plays important roles in the biological and physiological functions of haematopoietic and mesenchymal stem cells. This chemokine regulates the formation of multiple organ systems during embryogenesis. However, its roles in skeletal development remain unclear.

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Non‐canonical PKG1 regulation in cardiovascular health and disease

British Journal of Pharmacology, EarlyView.
It is well established that the cyclic GMP‐dependent protein kinase I (PKG1) is canonically activated by cyclic guanosine monophosphate (cGMP), enabling its regulation of vascular tone, cardiac function and smooth muscle homeostasis. However, diverse non‐canonical stimuli of PKG1 have also been identified.
