When is it an osteoclast? [PDF]
Using acid phosphatase as a marker, osteoclasts were examined from single sections of undemineralised iliac crest biopsies from patients with renal failure and from normal controls. Eighty one per cent of the cells from controls and 56% of the cells from patients with renal failure appeared to be non-nucleated or mononucleated.

Metabolic properties of the osteoclast [PDF]
Osteoclasts are defined as cells capable of excavating 3-dimensional resorption pits in bone and other mineralised tissues. They are derived from the differentiation/fusion of promonocytic precursors, and are usually large, multinucleated cells. In common with other cells from this myeloid lineage such as macrophages and dendritic cells, they are ...

A potent anionic citric acid‐based 3D‐printed scaffold is developed for the sustained and controlled release of orthobiologics to enhance orthopedic therapeutic efficacy. Comprehensive in vivo studies demonstrated effective bone fusion and high safety at a low dose of BMP‐2 delivered by the system, establishing it as a promising platform for safe ...

Osteoclasts are primary bone-resorbing cells, and receptor-activated NF-kB ligand (RANKL) stimulation is the key driver of osteoclast differentiation.

CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

Sexual Dimorphism in Osteoclasts [PDF]
Osteoclasts are the principal mediators of bone resorption. They form through the fusion of mononuclear precursor cells under the principal influence of the cytokines macrophage colony stimulating factor (M-CSF, aka CSF-1) and receptor activator of NF-κB ligand (RANKL, aka TNFSF11).

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes
Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

The Osteoclast—Not Always Guilty [PDF]
Osteopetrosis is usually regarded as the disease of nonfunctioning osteoclasts, with a consequent accumulation of osseocartilaginous material in the bone marrow. A recent report shows that, in some patients with the rare autosomal recessive form of the disease, the osteoclast defect may be non-cell autonomous, in this case due to a mutation in RANKL ...

Glucocorticoids Alter Bone Microvascular Barrier via MAPK/Connexin43 Mechanisms
Osteoporosis induced by Glucocorticoids (GCs) is a common complication of long‐term GC use in patients with inflammatory and autoimmune conditions, often leading to an increased fracture risk. A 3D bicellular endo‐osteo microfluidic platform is developed to explore pathogenic mechanisms underlying GCs‐induced osteoporosis, highlighting a novel MAPK ...

Objective: Nuclear factor-erythroid 2-related factor 2 (Nrf2) is shown to as a negative-regulatory cause in osteoclasts differentiation. Cannabinoid receptor type 2 (CB2) is verified to regulate osteoclast differentiation, though with diversed results ...
