Rock Climbing-Inspired Electrohydrodynamic Cryoprinting of Micropatterned Porous Fiber Scaffolds with Improved MSC Therapy for Wound Healing

CaO2–Cu2O micromotors accelerate infected wound healing through antibacterial functions, hemostasis, improved cell migration, and inflammatory regulation

“…The wound area is vulnerable to pathogens because of the lack of skin protection. 42 Therefore, antimicrobial activity is an essential requirement for an effective wound dressing. The SEM images (Fig.…”

Electrospray Nano-Micro Composite Sodium Alginate Microspheres with Shape-Adaptive, Antibacterial, and Angiogenic Abilities for Infected Wound Healing

“…To visualize the L929 cells, the cells were transinfected with GFP gene-inserted lentivirus (SyngenTech, China) according to our previous publication. 13 L929 cells were seeded in the lower chamber of a 24-well transwell plate at a density of 5 × 10 4 cells/well and cultured in complete 1640 medium with 10% (w/v) FBS and 1% P/S. After cell adhesion, we made a straight scratch on the cells using a 20 μm pipet.…”

Emerging Antimicrobial and Immunomodulatory Fiber-Based Scaffolding Systems for Treating Diabetic Foot Ulcers

“…Nanofibrous meshes containing human placenta-derived mesenchymal stem cells and platelet-rich plasma were also found to induce cell recruitment and proliferation to the injured area, and to stimulate wound closure, while reducing pain [ 49 ]. More recently, micropatterned fiber scaffolds prepared via the electrohydrodynamic cryo-printing method and bonded with adipose-derived mesenchymal stem cells were seen to improve the secretion of growth factors and chemokines, thus instigating fibroblast migration and vascular endothelial cell tube formation, along with collagen deposition and angiogenesis and reducing pro-inflammatory reactions [ 75 ].…”

“…Extensive revision work has been conducted on the properties, characteristics, and benefits of using each of these polymers [ 85 , 86 , 87 , 88 ]. Additionally, other techniques such as aqueous phase fiber reassembly [ 57 ] and cryoprinting [ 75 ] may also be used in the production of 3D fibrous scaffolding systems with great biological performance. Textile knitting is another very common technique for bandage production applied to DFUs care [ 29 , 89 ], either as a main ( Table 1 only reports studies in which knitted fiber constructs are the main therapy) or a co-adjuvant, protective therapy.…”
