TL;DR
Findings necessitate a redefinition of the role of neutrophils in bone repair and underscore the importance of exploring new concepts and directions in neutrophil biology.
Fibrosis has traditionally been viewed as a fibroblast- and myofibroblast-centred process, in which immune cells regulate matrix deposition primarily through inflammatory mediators and paracrine signalling. However, advances in single-cell profiling, spatial analyses and lineage-resolved approaches are beginning to cha...
It is proposed that macrophages represent a critical mechanistic link between hAMSC-sEV therapy and coordinated tissue repair and may suppress chronic inflammation while simultaneously supporting osteogenesis and neovascularization.
Bone regeneration is a complex, tightly regulated process involving coordinated interactions of immune and stromal cells. Early phases of healing rely on the timely clearance of debris, a task primarily carried out by macrophages and osteoclasts. However, the sequence of events leading to the presence of osteoclasts at...
Post-traumatic bone regeneration extends beyond a mere osteogenic event to encompass a dynamic reparative cascade characterized by the coordinated interplay of inflammation, nerve reinnervation, angiogenesis, mesenchymal stem cell differentiation, and osteoblast-osteoclast coupling. While immune and neural regulation...
Pulp tissue resides within rigid dentinal walls and depends on terminal circulation, making its healing capacity highly contingent on the degree of inflammation and suggesting the presence of intrinsic protective mechanisms to prevent necrosis. Multiple cell types including odontoblasts, fibroblasts, endothelial cells,...
Aging disrupts skeletal homeostasis, resulting in impaired fracture healing, increased risk of nonunion, and reduced regenerative capacity. These deficits are associated with dysregulated inflammation, impaired angiogenesis, and reduced osteogenesis, while current treatments remain limited in aged populations. This rev...
