Bone Marrow Macrophage STING Signaling is a Direct Nexus Linking Marrow Adipose Expansion to NAD+ Depletion and Osteogenic Decline in Skeletal Aging

Advanced Science, EarlyView.
This study reveals that during skeletal aging, bone marrow adipocyte‐derived sDPP4 primes STING signaling in macrophages. In combination with mitochondrial DNA, this signaling activates CD38 and depletes local NAD+/NMN, thereby impairing osteogenesis.

Osteoclast differentiation antigen [PDF]

, 1996
Osteoclasts are the primary cells which perform bone resorption. The origin of these multinucleated giant cells is the haematopoietic stem cells. The differentiation pathway of the osteoclasts has so far been well studied and the cell-lineage of ...

The role of osteoblast cells in the pathogenesis of unicameral bone cysts

, 2012
PurposeThe pathogenesis of unicameral bone cysts (UBCs) remains largely unknown. Osteoclasts have been implicated, but the role of osteoblastic cells has, to date, not been explored.

Gut Microbiota‐Derived Indole‐3‐Propionic Acid Alleviates Diabetic Osteoporosis Through Nrf2‐Mediated Ferroptosis Suppression

Advanced Science, EarlyView.
Diabetes‐associated dysbiosis is accompanied by reduced Clostridium abundance, impaired microbial tryptophan metabolism, and lower circulating indole‐3‐propionic acid (IPA). Exogenous IPA improves trabecular microarchitecture and bone formation and restores Nrf2‐associated antioxidant signaling in bone marrow mesenchymal stem cells, limiting iron ...

Regulation of osteoclast differentiation by the redox-dependent modulation of nuclear import of transcription factors

, 2019
This study sought to characterize the reduced glutathione (GSH)/oxidized GSSG ratio during osteoclast differentiation and determine whether changes in the intracellular redox status regulate its differentiation through a RANKL-dependent signaling pathway.

Osteoclast differentiation.

, 2018
2A shows the Trap staining: After addition of Rankl to the four groups for 7 days, the cells were fixed and stained for Trap. The osteoclasts were stained red. The white-black arrows indicate the osteoclasts.

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Basic-helix-loop-helix family member e41 suppresses osteoclastogenesis and abnormal bone resorption disease via NFATc1

iScience
Summary: Overactivation of osteoclasts due to altered osteoclastogenesis causes multiple bone metabolic diseases. However, how osteoclast differentiation is tightly regulated and involved in multiple pathophysiological states remains mystery.

Effects of Zinc and Strontium Substitution in Tricalcium Phosphate on Osteoclast Differentiation and Resorption

, 2013
Bone replacement materials must be able to regulate both osteoblastic synthesis of new bone and osteoclastic resorption process in order to maintain the balance of bone remodeling. Osteoclasts generate from differentiation of mononuclear cells.
