Effects of mechanical stress on chondrocyte phenotype and chondrocyte extracellular matrix expression [PDF]

open access: yesScientific Reports, 2016
AbstractMechanical factors play a key role in regulating the development of cartilage degradation in osteoarthritis. This study aimed to identify the influence of mechanical stress in cartilage and chondrocytes. To explore the effects of mechanical stress on cartilage morphology, we observed cartilages in different regions by histological and ...

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Cell Calcification Models and Their Implications for Medicine and Biomaterial Research

open access: yesAdvanced Healthcare Materials, EarlyView.
Calcification, is the process by which the tissues containing minerals are formed, occurring during normal physiological processes, or in pathological conditions. Here, it is aimed to give a comprehensive overview of the range of cell models available, and the approaches taken by these models, highlighting when and how methodological divergences arise,

Gene Delivery to Chondrocytes

open access: yes, 2023
AbstractDelivering genes to chondrocytes offers new possibilities both clinically, for treating conditions that affect cartilage, and in the laboratory, for studying the biology of chondrocytes. Advances in gene therapy have created a number of different viral and non-viral vectors for this purpose.

Bioassembly of Region‐Specific Fibrocartilage Microtissues to Engineer Zonally Defined Meniscal Grafts

open access: yesAdvanced Healthcare Materials, EarlyView.
Meniscal microtissues are fabricated using progenitor cells isolated from the inner (iMPCs) and outer (oMPCs) regions of the meniscus. Meniscal microtissues fuse into cohesive constructs rich in sGAG and collagen. cABC treatment modulates collagen fiber formation and organization in assembled grafts.
