摘要: In vitro techniques were used to evaluate the interactions between Fibroblastic cells and Poly(p-Dioxanone) PPDX compared its performance with that of other polymeric substrates. biocompatibility was assessed by studying cell adhesion growth on polymer films themselves as well in media enriched degradation products Poly(glycolic)/Poly(L-lactide 90:10 copolymer (PGLA-910). Our results show althought all polymers tested suitable for initial attachment, proved be most favorable surface growth; density after 48 h culture similar obtained tissue Polystyrene TCPS (control). No signs damage detected using scanning electron microscopy (SEM) where h. seeding PPDX, fibroblast exhibited a confluent multilayer TCPS. addition, hydrolytic had no citotoxic effect adherence proliferation fibroblastic The starts amorphous regions, tie-chain segments these regions degrade into fragments causing pH decrease buffer solution weight loss degradable polymers. evaluation suggests may candidate biomaterial construction cell-polymer matrix.
