Mesenchymal Stem Cells in Oriented PLGA/ACECM Composite Scaffolds Enhance Structure-Specific Regeneration of Hyaline Cartilage in a Rabbit Model

Stem Cells International, 2018
Articular cartilage lacks a blood supply and nerves. Hence, articular cartilage regeneration remains a major challenge in orthopedics. Decellularized extracellular matrix- (ECM-) based strategies have recently received particular attention. The structure

Injectable Dual‐Network Hydrogel System for Osteochondral Repair Combining Immunomodulation, Mechanical Adaptability, and Enhanced Tissue Integration

Advanced Functional Materials, EarlyView.
A UV‐triggered injectable dual‐network hydrogel is reported as the first application of bletilla striata polysaccharide (BSP) in osteochondral repair. By integrating methacrylamide‐modified BSP and nitrobenzaldehyde‐functionalized hyaluronic acid, the system achieves immunomodulation, mechanical reinforcement, and dynamic tissue adhesion, thereby ...

Augmented cartilage regeneration by implantation of cellular versus acellular implants after bone marrow stimulation: a systematic review and meta-analysis of animal studies [PDF]

PeerJ, 2017
Bone marrow stimulation may be applied to regenerate focal cartilage defects, but generally results in transient clinical improvement and formation of fibrocartilage rather than hyaline cartilage.

An Injectable Platform of Engineered Cartilage Gel and Gelatin Methacrylate to Promote Cartilage Regeneration

Frontiers in Bioengineering and Biotechnology, 2022
Cell–hydrogel constructs are frequently used as injectable platforms for irregular cartilage regeneration. However, cell–hydrogel constructs have obvious disadvantages, such as long culture times, high probability of infection, and poor cartilage ...

Dense Nanofibrillar Collagen–Silica Hybrids with High Strength and ECM‐Mimetic Tissue Integration

Advanced Functional Materials, EarlyView.
Dense nanofibrillar collagen–silica hybrids are engineered by synchronizing collagen fibrillogenesis with silica condensation, producing printable scaffolds that unexpectedly approach native extracellular matrix organization and strength. These cell‐free constructs guide endogenous cell‐infiltration, enable localized matrix remodeling, and integrate ...

Cartilage regeneration in zebrafish depends on Nrg1/ErbB signaling pathway

Frontiers in Cell and Developmental Biology, 2023
Objective: Cartilage, as the majority of adult mammalian tissues, has limited regeneration capacity. Cartilage degradation consecutive to joint injury or aging then leads to irreversible joint damage and diseases.
