Engineered 3D cultured human nasal mucosa mesenchymal stem cell derived sEVs for targeted brain‐derived neurotrophic factor delivery to enhance neurogenesis and attenuate brain damage

open access: yesInterdisciplinary Medicine, EarlyView.
This study successfully developed and evaluated BDNF@RVG‐sEVs, a novel brain‐targeted nanomedicine based on hnmMSC‐derived sEVs, designed to overcome the BBB and enhance neurorestoration. By integrating RVG for enhanced brain targeting and encapsulating BDNF for potent neurorepair, our system address the key limitations of the conventional sEVs and ...

Plasma and Synovial Fluid VEGF‐A and Neuropilin‐1 in Knee Osteoarthritis: Associations With Radiographic Severity, Pain Sensitization‐Related Features, and Disease Burden

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to investigate associations of plasma and synovial fluid vascular endothelial growth factor A (VEGF‐A) and neuropilin‐1 (NRP1) levels with radiographic severity, pain sensitization‐related features, and disease burden in knee osteoarthritis (KOA). Plasma VEGF‐A and NRP1 were measured by sandwich ELISA in 120 patients with KOA (

Recent Advances in Cryogel Applications for Musculoskeleatal Regeneration

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Hydrogels have been widely used in tissue engineering due to their high‐water content and biocompatibility, yet their densely cross‐linked microstructure inherently limits cell infiltration, mass transport, and mechanical support. Cryogels, formed through partial freezing and crosslinking under subzero conditions, provide unique 3D macroporous

Innovative 3D‐bioprinted microfibers in calcium phosphate cement platform with Nell‐1 to activate nerve‐bone axis for synergistic bone, vasculature, and nanofibrous nerve regeneration

open access: yesSmart Molecules, EarlyView.
A 3D‐bioprinted platform with stem cells activates “nerve‐bone” signaling by enabling the spatiotemporal delivery of Nell‐1. This activation enhances neurovascular and bone regeneration through the CYFIP1 cascade. In rat calvarial defects, the platform doubled bone regeneration and nerve repair and tripled vascular density, resulting in superior ...
