The musculoskeletal system,which is vital for movement,support,and protection,can be impaired by disorders such as osteoporosis,osteoarthritis,and muscular dystrophy.This review focuses on the advances in tissue engineering and regenerative medicine,specifically aimed at alleviating these disorders.It explores the roles of cell therapy,particularly Mesenchymal Stem Cells(MSCs)and Adipose-Derived Stem Cells(ADSCs),biomaterials,and biomolecules/external stimulations in fostering bone and muscle regeneration.The current research underscores the potential of MSCs and ADSCs despite the persistent challenges of cell scarcity,inconsistent outcomes,and safety concerns.Moreover,integrating exogenous materials such as scaffolds and external stimuli like electrical stimulation and growth factors shows promise in enhancing musculoskeletal regeneration.This review emphasizes the need for comprehensive studies and adopting innovative techniques together to refine and advance these multi-therapeutic strategies,ultimately benefiting patients with musculoskeletal disorders. 展开更多

Modulating inflammatory cells in an implantation site leads to severe complications and still unsolved challenges for blood-contacting medical devices.Inspired by the role of galectin-1(Gal-1)in selective functions on multiple cells and immunomodulatory processes,we prepared a biologically target-specific surface coated with the lipid bilayer containing Gal-1(Gal-1-SLB)and investigate the proof of the biological effects.First,lipoamido-dPEG-acid was deposited on a gold-coated substrate to form a self-assembled monolayer and then conjugated dioleoylphosphatidylethanolamine(DOPE)onto that to produce a lower leaflet of the supported lipid bilayer(SLB)before fusing membrane-derived vesicles extracted from B16-F10 cells.The Gal-1-SLB showed the expected anti-fouling activity by revealing the resistance to protein adsorption and bacterial adhesion.In vitro studies showed that the Gal-1-SLB can promote endothelial function and inhibit smooth muscle cell proliferation.Moreover,Gal-1-SLB presents potential function for endothelial cell migration and angiogenic activities.In vitro macrophage culture studies showed that the Gal-1-SLB attenuated the LPS-induced inflammation and the production of macrophage-secreted inflammatory cytokines.Finally,the implanted Gal-1-SLB reduced the infiltration of immune cells at the tissue-implant interface and increased markers for M2 polarization and blood vessel formation in vivo.This straightforward surface coating with Gal-1 can be a useful strategy for modulating the vascular and immune cells around a blood-contacting device. 展开更多
