Stem Cell-laden 3D Bioprinting for Osteoarthritis: Orchestrating Chondrogenic Induction and Inflammatory Microenvironment Modulation
Osteoarthritis (OA) involves irreversible cartilage degeneration and requires regenerative strategies due to limited self-repair. This review highlights the potential of stem cell-laden 3D bioprinting to engineer biomimetic cartilage scaffolds with precise control. It analyzes bioprinting methods, bioinks, and cell induction strategies, focusing on the synergistic roles of small molecules, growth factors, and exosomes in guiding stem cell differentiation.

Expert Opinion on Allogeneic Bone Marrow-Derived Mesenchymal Stem Cell (BMMSC) Therapy for Knee Osteoarthritis: Clinical Insights, Efficacy, and Safety
Knee osteoarthritis (KOA) remains a major cause of disability. Many patients with moderate disease (Kellgren-Lawrence (KL) grade 2-3) continue to experience disease progression, despite receiving guideline-based conservative treatments that primarily offer symptomatic relief. Allogeneic bone marrow-derived mesenchymal stem cells (BMMSCs) have gained attention for their potential anti-inflammatory, immunomodulatory, and chondroprotective effects.

Research Landscape of Stem Cell Applications in Musculoskeletal Tissue: A Scoping Review
Stem cell therapy represents an intrinsic part of regenerative medicine, with expanding applications in orthopedic and musculoskeletal research. Although studies span from small-animal models to early-phase clinical trials, the field remains fragmented, with wide variation in stem cell types, delivery methods, and target tissues.

Comparative Efficacy of Different Doses of Mesenchymal Stem Cells Derived from Different Tissue Sources for Knee Osteoarthritis: A Systematic Review and Network Meta-Analysis of Randomized Controlled Trials
Knee osteoarthritis (KOA) remains a leading cause of disability, and mesenchymal stem cells (MSCs) show potential for KOA treatment. However, existing studies demonstrate conflicting results on the optimal dose and tissue source of MSCs for KOA treatment. This gap limits evidence-based treatment decisions.

Chondrogenesis of Peripheral Blood-Derived Mesenchymal Stromal Cells
Articular cartilage, a highly specialised and avascular tissue, exhibits limited regenerative potential following trauma or degenerative conditions such as osteoarthritis (OA). Conventional surgical interventions, including microfracture and autologous chondrocyte implantation (ACI), have shown limited long-term efficacy due to donor site morbidity and restricted cell proliferation. In this context, mesenchymal stromal cells (MSCs) have emerged as a promising alternative owing to their multipotency, self-renewal capacity, and low immunogenicity. While bone marrow (BM) remains the traditional source of MSCs, recent studies have reported that peripheral blood-derived mesenchymal stromal cells (PB-MSCs) may possess chondrogenic, osteogenic, and adipogenic potential comparable to that of BM-derived MSCs.

Biological Treatment in Meniscus Injury
Meniscal injuries, common in sports, often cause knee pain and instability. The meniscus plays a key role in pressure distribution and joint stability, making its repair essential. Treatments range from conservative approaches to surgical interventions, with growing interest in biological factors such as growth factors, mesenchymal stem cells, platelet-rich plasma, fibrin clot, and tenocyte to enhance healing. This review compares the effects of these biological agents in meniscal repair, examining their mechanisms, limitations, and clinical outcomes.
Biologics for bone regeneration: advances in cell, protein, gene, and mRNA therapies
Bone fractures represent a significant global healthcare burden. Although fractures typically heal on their own, some fail to regenerate properly, leading to nonunion, a condition that causes prolonged disability, morbidity, and mortality. Biologic therapies have emerged as promising tools to enhance bone regeneration by leveraging the body's natural healing processes. This review explores the critical role of conventional and emerging biologics in fracture healing.
