Preparation of poly(glycolic acid) bonded fiber structures for cell attachment and transplantation

Abstract: A novel method was developed to prepare three-dimensional structures with desired shapes used as templates for cell transplantation. The produced biomaterials are highly porous with large surface/volume and provide the necessary space for attachment and proliferation of the transplanted cells. The processing technique calls for the formation of a composite material with nonbonded fibers embedded in a matrix followed by thermal treatment and the selective dissolution of the matrix. To evaluate the technique, po… Show more

“…Publicadas na literatura científica (concomitantemente às requisições de patentes nos EUA), as técnicas de preparo de suportes porosos foram descritas em culturas de células específicas, e ainda representam um importante enfoque de desenvolvimentos [41] . Entre as técnicas podemos destacar: fiber bonding [42] , evaporação de solvente com adição e lixiviação de sal (solvent casting -particulate leaching) [43] , inversão de fases [44] , injeção de gás [45] , fused deposition modeling (FDM) [46] , freeze-dried [47] e outras.…”

“…Another study used a mesh on the tensile side of CPC to increase the work-to-fracture [45]. Macropores were built into implants to facilitate cell infiltration, tissue ingrowth, and implant fixation [3,6,17,18,20,24,[26][27][28]301. Our recent studies incorporated a variety of fibers, as well as water-soluble porogens, into CPC to obtain strength as well as macropores for bone ingrowth [46,49].…”

“…Polyglycolic acid (PGA) scaffold has been a workhorse of tissue-engineering experiments and is commercially available in the form of biodegradable sutures. The addition of poly(L-lactic) acid (PLLA) to form a composite has been successful both in vivo and in vitro (Mikos et al 1993;Grikscheit et al 2003c). RGD peptides (R, arginine; G, glycine; D, aspartic acid) promote cell adhesion and ingrowth through integrin binding (Hersel et al 2003).…”
