Fabrication of Porous Hydroxyapatite-Gelatin Scaffolds Crosslinked by Glutaraldehyde for Bone Tissue Engineering
In this study, to mimic the mineral and organic components of natural bone, hydroxyapatite[HA] and gelatin[GEL] composite scaffolds were prepared using the solvent-casting method combined with a freeze drying process. Glutaraldehyde[GA] was used as a cross linking agent and sodium bisulfite was used as an excess GA discharger. Using this technique, it is possible to produce scaffolds with mecha...
متن کاملThe micro patterning of glutaraldehyde (GA)-crosslinked gelatin and its application to cell-culture.
This paper proposes a novel technique for fabricating micro patterns of glutaraldehyde (GA)-crosslinked gelatin. It provides another means to crosslink gelatin other than using photo-sensitizing agents, and the micro patterns of GA-crosslinked gelatin can still be made successfully by accessing conventional photolithography. A much less toxic and increased biocompatible approach to strengthenin...
متن کاملFormulation and Evaluation of Bupivacaine-Loaded Glutaraldehyde-Crosslinked High Molecular Weight Chitosan Microspheres
Purpose: To develop a chitosan microsphere carrier system of bupivacaine for buccal administration. Methods: Chitosan microspheres loaded with bupivacaine were prepared by emulsification technique based on glutaraldehyde cross-linking and drug-loaded chitosan microsphere were coated with polyglycolic acid (PGA) film The formulated microspheres were characterized by x-ray diffraction (XRD), diff...
متن کاملClick-Crosslinked Injectable Gelatin Hydrogels.
Injectable gelatin hydrogels formed with bioorthogonal click chemistry (ClickGel) are cell-responsive ECM mimics for in vitro and in vivo biomaterials applications. Gelatin polymers with pendant norbornene (GelN) or tetrazine (GelT) groups can quickly and spontaneously crosslink upon mixing, allowing for high viability of encapsulated cells, establishment of 3D elongated cell morphologies, and ...
متن کاملMechanical properties of skinned single muscle fibers crosslinked with glutaraldehyde.
It was shown earlier (Mikawa 1979; Prochniewicz 1979) that crosslinking of thin filaments in vitro by glutaraldehyde can "'freeze'" their structure either in the activated (in the presence of Ca"-ions) or depressed (in the absence of C a t ions) state. This treatment does not inhibit the ability of actin to bind to myosin heads and to activate myosin ATPase (Lehrer 1981; Prochniewicz-Nakayama a...
