Abstract:
[Objective] The biocompatibility between SGBG/PHBV and human PDLC were investigated to provide a basis for the choice of the scaff material of periodontal tissue engineering.[Methods] Human PDLC were cultured using tissue-explant technique.Seeding on 96 wells plate,9 wells for one group,Four different concentrations (100％,75％,50％,25％,0％) of maceration extract of SGBG/PHBV were added into the culture plantsafter 48-h cell seeding,the grades of the cytotoxicity of SGBG/PHBV was evaluated by MTT assay.Human PDLC cultured in vitro were collected and seeded on the three-dimensional scaffolds of SGBG/PH-BV,the cellular morphology and cell growth on the scaffolds were observed and photographed by scanning electronic microscope.HumanPDLC seeded on the three-dimensional scaffolds of SGBG/PHBV in the experimental group,and human PDLC seeded by DMEM in the control group,after 12-,24-,and 48-h cell seeding,got 27 simples for each group,and the affection of the SGBG/PHBV on cell secretory function was observed by spectrophotometry which assayed the biochemical indexes ALP in supinate.[Results] The grades of the cytotoxicity of SGBG/PHBV were 0 and 1.It was displayed that human PDLC adhered and proliferated well on the scaffold of SGBG/PHBV under the scanning electronic microscope.The significant difference of ALP in supinate between the experimental group and the control group (P ＜ 0.05).[Conclusions] SGBG/PHBV had no cytotoxicity to human PDLC.SGBG/PHBV is potential to further study as the scaffolds of periodontal tissue engineering since it displayed the satisfactory biocompatibility with human PDLC.
