Autophagy drives osteogenic differentiation of human gingival mesenchymal stem cells

open access: yesCell Communication and Signaling, 2019
Background/aim Autophagy is a macromolecular degradation process playing a pivotal role in the maintenance of stem-like features and in the morpho-functional remodeling of the tissues undergoing differentiation.

Ion‐Driven Regulation of Ca2+ Flow by Ti/Zn Composite Activates ERK/MAPK Signaling and Maintains Mitochondrial Homeostasis to Promote Macrophage‐Mediated Bone Regeneration

open access: yesAdvanced Science, EarlyView.
A 3D‐printed interpenetrating Ti/Zn composite enables sustained Zn2+ release to regulate intracellular Ca2+ redistribution, preserve mitochondrial homeostasis, activate ERK/MAPK signaling, and promote M2 macrophage polarization, thereby enhancing osteoimmune‐mediated bone regeneration and peri‐implant osseointegration.

FOXG1 promotes osteogenesis of bone marrow-derived mesenchymal stem cells by activating autophagy through regulating USP14

open access: yesCommunications Biology
The osteogenic differentiation of bone marrow-derived mesenchymal stem cells (BMSCs) is key for bone formation, and its imbalance leads to osteoporosis.

Bioadhesive‐Integrated 3D‐Printed Multilayer Scaffolds Secure a Mechanically‐Stable Osteoimmune Niche for Enhanced Bone Augmentation

open access: yesAdvanced Science, EarlyView.
A 3D‑printed multilayer adhesive scaffold, firmly anchored to bone defects by simple finger pressing, suppresses micromotion and secures mechanical stability of the osteogenic niche. This stabilization likely contributes to the enhanced bone augmentation by fostering a pro‑regenerative mechano‐immune profile—characterized by M2‑like macrophage ...

Maternal Exercise Rescues Embryonic Osteogenesis Impaired due to POLG Mutation Through a Potential Apelin‐ATF4 Axis

open access: yesAdvanced Science, EarlyView.
Maternal exercise (ME) increases apelin abundance across maternal and fetal tissues and is associated with improved fetal osteogenesis under POLG mutation‐induced mitochondrial dysfunction. Apelin‐APJ signaling is linked to enhanced mitochondrial function, Akt phosphorylation, and ATF4‐RUNX2 association, supporting coordinated fetal bone remodeling ...

Dysregulation of the MACF1‐Rab14/KIF16B‐FGFR Vesicular Trafficking Axis Skews MSC Lineage Commitment in Glucocorticoid‐Induced Osteoporosis

open access: yesAdvanced Science, EarlyView.
Under normal conditions, MACF1 interacts with Rab14 and facilitates KIF16B‐mediated FGFR vesicle trafficking along microtubules to the plasma membrane, thereby supporting BMSC differentiation. In contrast, chronic GC exposure suppresses MACF1 expression, disrupting this transport and causing intracellular FGFR retention, which blunts osteogenic ...

Machine Learning‐Driven Design of Multicomponent Bone Inorganic Matrix Mimicking Scaffolds for Osteogenesis Enhanced by Neurogenesis

open access: yesAdvanced Science, EarlyView.
Schematic illustration of development of experimental datasets and algorithm models, screening and preparation of the scaffolds and their applications in vivo. ABSTRACT Bone defects require materials with osteogenic, neurogenic, and angiogenic activity, yet designing such materials within high‐dimensional compositional spaces remains challenging. Here,
