Based on stereo-lithography, the polyacrylamide hydrogel scaffolds with controlled accurate internal structures were fabricated. The structure accuracy of the scaffolds was evaluated by the size measurement compared with the CAD model. The mechanical property evaluation showed that the hydrogel compressive modulus of elasticity reached 4.54MPa, which was similar to that of the articular cartilage,...
Poly(vinyl-alcohol) (PVA) hydrogels have long been investigated as replacement materials for articular cartilage, but their lack of bioactivity has impeded their utility. We have prepared bioactive PVA hydrogels by incorporating a degradable phase of poly(lactic-co-glycolic acid) (PLGA) that enhances porosity and controls the release of growth factors. Hydrogel properties such as porosity, pore size,...
To mimic natural extracellular matrix architecture, the poly (L-lactic acid) (PLLA) scaffolds loading icariin and icariin-2-hydroxypropyl-beta-cyclodextrin inclusion complex were prepared via phase separation, solvent replacement and freeze-drying. The morphologies of PLLA scaffolds were visualized with scanning electron microscopy, the icariin concentration and drug release in vitro were determined...
Biodegradable polymers have been widely used as scaffolding materials to regenerate new tissues. To mimic natural extracellular matrix architecture, a novel highly porous structure, which is a three-dimensional interconnected fibrous network with a fiber diameter ranging from 100 to 500 nm, has been created from poly (L-lactic acid) in this work. These fibrous matrices were prepared from the polymer...
Today, one of the limitations associated with cartilage grafting is the lack of bonding between the implanted materials and the natural tissue. Helical rosette nanotubes (HRNs) are novel biomimetic self-assembled supramolecular structures whose basic building blocks are DNA base-pairs, which can solidify into a viscous gel at body temperatures in short periods of time. HRNs are similar in size to...
Human embryonic germ (hEG) cells have the potential to self-renew over long periods of time and differentiate into various lineages. Cells derived from embryoid bodies of hEG cells express a broad spectrum of gene markers and have been induced towards cells of ecto-dermal and recently endo-dermal and mesenchymal lineages. LVEC cells express a number of surface marker proteins characteristic of mesenchymal...
